The major enzyme that catalyzes the reduction of carbon dioxide is called.

Answers

Answer 1

The major enzyme that catalyzes the reduction of carbon dioxide is called Rubisco.

Rubisco is an abbreviation for ribulose bisphosphate carboxylase/oxygenase, which is an enzyme found in the chloroplasts of plant cells that catalyzes the first step in the Calvin cycle, a biochemical pathway that converts carbon dioxide into glucose. Rubisco catalyzes the reaction of carbon dioxide (CO₂) with ribulose bisphosphate (RuBP) to create two molecules of 3-phosphoglycerate (3-PGA).

Rubisco's activity is critical in the Earth's carbon cycle, converting carbon dioxide from the atmosphere into organic molecules that organisms can use. However, Rubisco is an inefficient enzyme, and the reaction it catalyzes is frequently limited by the availability of CO₂. Furthermore, Rubisco's oxygenation activity can lead to photorespiration, a process that reduces the efficiency of carbon fixation in plants.

Helium is a gas used to fill balloons.it is present in the air in very small quantitie.diffusion can be used to separate it from the air. air at 1000 degrees Celsius is on one side of a porous barrier.the air which passes through the barrier has a large amount of helium in it. why does the air on the other side of the barrier contain more helium?​

Answers

The air on the other side of the barrier contains more helium because helium diffuses through the porous barrier more quickly than other gases in the air. At high temperatures, the rate of diffusion of gases increases due to the increased kinetic energy of the gas molecules. As a result, the helium molecules diffuse through the porous barrier more quickly than other gases in the air, such as nitrogen and oxygen. This leads to an enrichment of helium on the other side of the barrier, where the air has a higher concentration of helium compared to the original air at 1000 degrees Celsius.

what volume of a 0.12 m koh solution is needed to react with 23. ml of 0.22 m hcl? the reaction is:

Answers

42.1 ml volume of a 0.12 M KOH solution required to react with 23 mL of 0.22 M HCl.

The balanced chemical equation for the reaction between KOH and HCl is:

KOH + HCl -> KCl + H₂O

From the equation, we can see that ,

one mole of KOH reacts with one mole of HCl, resulting in the formation of one mole of KCl and one mole of water.

This means that the molar ratio of KOH to HCl is 1:1.

Using the formula Molarity (M) = moles/volume (L), we can calculate the number of moles of HCl:

moles of HCl = Molarity of HCl × volume of HCl solution

= 0.22 mol/L × 0.023 L

= 0.00506 mol

Since the molar ratio of KOH to HCl is 1:1, we need an equal number of moles of KOH to react completely with the given amount of HCl. Therefore, the number of moles of KOH required is also 0.00506 mol.

Now for volume of KOH solution = moles of KOH/ Molarity of KOH

= 0.00506 mol/ 0.12 mol/L

= 0.0421 L

= 42.1 mL

Therefore, 42.1 mL of the 0.12 M KOH solution is needed.

the process used to mine salts by filling shallow ponds with sea water is

Answers

The process used to mine salts by filling shallow ponds with seawater is known as solar salt production.

The process of mining salts by filling shallow ponds with seawater is called solar salt production. It is a method commonly used to extract salt from seawater on a large scale. The process takes advantage of the natural evaporation of water under the sun, leaving behind concentrated salt crystals that can be collected and processed.

The process begins by selecting suitable coastal areas or salt flats, typically in arid or semi-arid regions with access to the sea. These areas are usually flat and have low rainfall, facilitating the evaporation process. Shallow ponds or basins, also known as salt pans or evaporation ponds, are constructed to contain the seawater.

Seawater is then pumped into these ponds or is allowed to flow in naturally during high tide. The ponds are designed to maximize the exposure of seawater to sunlight and heat. The sun's energy drives the evaporation process, causing the water to gradually evaporate, leaving behind concentrated brine solutions.

Over time, as the water continues to evaporate, the salt concentration in the remaining brine increases. The concentrated brine, also known as bittern, becomes supersaturated with dissolved salts, including sodium chloride and other minerals. As the saturation point is reached, salt crystals begin to precipitate and form salt beds at the bottom of the ponds.

Answers

Based on the information provided, the principle of the conservation of mass did apply in this example.

The principle of the conservation of mass states that mass is neither created nor destroyed in a chemical reaction. In other words, the total mass of the reactants should be equal to the total mass of the products.

In the given scenario, Nicole measured 25 g of sodium carbonate and 10 mL of vinegar, which can be considered the reactants. The total mass of the reactants and the beaker was determined to be 100 g. After mixing the reactants, bubbling and a white residue were observed, and the total mass became 98 g.

To analyze the conservation of mass, we need to consider the mass of the products formed. The bubbling and white residue suggest a chemical reaction occurred, likely resulting in the formation of a gas and a solid product. Although the exact reaction and products are not specified, it is evident that some change took place.

The total mass decreasing from 100 g to 98 g indicates that the mass of the products is less than the mass of the reactants and the beaker. This might be due to the formation of a gas that escaped from the reaction mixture.

While the total mass decreased, it is important to note that mass was not created or destroyed. The lost mass in the form of the escaping gas can be accounted for if it is considered separately.

what is the molarity of a solution containing 20 grams of naoh in 500

Answers

The solution containing 20 g of NaOH has a molarity of 1.00 M in 500 milliliters.

To determine the molarity of a solution, we need to know the volume of the solution in liters and the number of moles of the solute.

First, let's figure out how many moles of NaOH there are:

Molar mass of NaOH = 22.99 g/mol (atomic mass of Na) + 16.00 g/mol (atomic mass of O) + 1.01 g/mol (atomic mass of H)

= 39.99 g/mol

Number of moles of NaOH = mass / molar mass

= 20 g / 39.99 g/mol

= 0.500 mol

Next, we convert the volume of the solution from milliliters to liters:

Volume of the solution = 500 mL = 500/1000 L = 0.500 L

Finally, we can calculate the molarity (M) using the formula:

Molarity (M) = moles of solute / volume of solution in liters

                    = 0.500 mol / 0.500 L

                                 = 1.00 M

Therefore, the molarity of the solution containing 20 g of NaOH in 500 milliliters of solution is 1.00 M.

determine the amount of energy released when 1.00 mol of sulfur trioxide is produced

Answers

The amount of energy released when 1.00 mol of SO3 is produced is -395 kJ/mol.

Given that 1.00 mol of sulfur trioxide is produced, we have to find out the amount of energy released during the reaction.

The reaction for the production of sulfur trioxide is given as;2SO2(g) + O2(g) ⟶ 2SO3(g)The balanced equation shows that the reaction produces 2 mol of SO3 for every 2 mol of SO2 and 1 mol of O2, which means the reaction produces 2 mol of SO3 for every 3 mol of O2 reacted.

So, 1.00 mol of SO3 is produced by reacting (3/2) × 1.00 mol of O2.

The energy released during this reaction is given by the enthalpy change of the reaction, which is -395 kJ/mol, and it is negative because the reaction is exothermic and releases energy.

The enthalpy change (-395 kJ/mol) corresponds to the reaction producing 2 mol of SO3.

Therefore, to find the amount of energy released when 1.00 mol of SO3 is produced, we need to calculate the amount of energy released when 2 mol of SO3 is produced and divide it by 2.

This is done to convert the energy released to per 1.00 mol of SO3 produced.

The amount of energy released when 2 mol of SO3 is produced = 2 × (-395 kJ/mol) = -790 kJ/mol

The amount of energy released when 1.00 mol of SO3 is produced = (-790 kJ/mol) ÷ 2= -395 kJ/mol

Therefore, the amount of energy released when 1.00 mol of SO3 is produced is -395 kJ/mol.

where does the co2 released in cellular respiration come from

Answers

The carbon dioxide (CO₂) released in cellular respiration comes from glucose molecules during the process of oxidation.

Cellular respiration is a metabolic process that converts energy stored in the chemical bonds of organic molecules into a more usable form of energy (ATP). This process occurs in the mitochondria of eukaryotic cells. During cellular respiration, glucose molecules are oxidized and broken down into carbon dioxide, water, and energy. The oxygen we breathe in is necessary for this process to occur.

Specifically, the carbon dioxide released in cellular respiration comes from the carbon atoms in glucose. In glycolysis, the first stage of cellular respiration, glucose is broken down into two pyruvate molecules. In the citric acid cycle, the pyruvate is further broken down into carbon dioxide, which is released as a waste product. Finally, in the electron transport chain, the carbon dioxide produced in earlier stages is fully oxidized to release additional energy in the form of ATP.

Step 1: Dehydration of 1-hexanol using sulfuric acid[SO4H2]H2SO4[latex]\rightarrow[/latex]C6H14O (1-hexanol) [latex]\rightarrow[/latex]C6H12 (1-hexene) + H2OThis reaction involves the removal of the hydroxyl group from 1-hexanol in the presence of concentrated sulfuric acid (H2SO4) to produce 1-hexene.

Step 2: Hydrogenation of 1-hexene in the presence of Lindlar catalystC6H12 (1-hexene) + H2 (hydrogen) [latex]\rightarrow[/latex]C6H14 (hexane)C6H14 (hexane) + NH3 (ammonia) [latex]\rightarrow[/latex]C5H11NH2 (pentylamine)

The hydrogenation of 1-hexene is done in the presence of Lindlar's catalyst, which is a poisoned catalyst that reduces the degree of hydrogenation to an alkene. This reaction converts 1-hexene to hexane, which is further treated with ammonia to yield pentylamine.

The reaction between hexane and ammonia forms pentylamine as shown below:

C6H14 (hexane) + NH3 (ammonia) [latex]\rightarrow[/latex]C5H11NH2 (pentylamine)

Hence, the overall reaction can be summarized as follows:

1-hexanol [latex]\xrightarrow{\text{Dehydration}}[/latex] 1-hexene [latex]\xrightarrow{\text{Hydrogenation}}[/latex] hexane [latex]\xrightarrow{\text{Ammonolysis}}[/latex]

the term used to denote concentration of electrolytes in a given volume is

Answers

The term used to denote the concentration of electrolytes in a given volume is "molarity".

Molarity-

Molarity is the number of moles of solute dissolved in one liter of the solution. Molarity is the most widely used concentration metric in chemistry, and it is frequently denoted by "M." It denotes the amount of solute in moles per liter of solution.

A solution's molarity can be calculated using the following formula:

Molarity = moles of solute / liters of solution

Molarity is often used to express the concentration of a solution's electrolytes because electrolytes break into ions when dissolved in a solvent, allowing for electrical conductivity.

Molarity can be used in other applications, such as stoichiometry, which involves determining how much of one compound is required to react completely with another.

Molarity is a useful tool for solving problems that involve chemical reactions since the number of moles of a substance is frequently used to establish reaction ratios, limit reactants, and determine the theoretical yield.

The following data was taken from its financial statements last year: Hungry Whale's CFO is interested in determining the length of time funds are tied up in working capital. Use the information in the preceding table to complete the following table. (Note: Use 365 days as the length of a year in all calculations, and round all values to two decimal places.) Both the inventory conversion period and payables deferral period use the average daily COGS in their denominators, whereas the average collection period uses average daily sales in its denominator. Why do these measures use different inputs? Current assets should be divided by sales, but current liabilities should be divided by the COGS. Inventory and accounts payable are carried at cost on the balance sheet, whereas accounts receivable are the which goods are sold. Is there generally a positive or negative relationship between net working capital and the cash conversion cycle?

The company's management expects that it will take 50 days to manufacture and sell its products and 40 days to receive payment from its customers. Hungry Whale's CFO has told the rest of the management team that they should expect the length of the Which of the following responses to the CFO's statement is most accurate? The CFO's approximation of the length of the bank loans should be accurate, because it will take 90 days for the company to manufacture, sell, and collect cash for its goods. All these things must occur for the company to be able to repay its loans from the bank. The CFO is not taking into account the amount of time the company has to pay its suppliers. Generally, there is a certain length of time between the purchase of materials and labor and the payment of cash for them. The CFO can reduce the estimated length of the bank loan by this amount of time. Setting and implementing a credit policy is important for three main reasons: It has a minor effect on sales, it influences the amount of funds tied up in receivables, and it affects bad debt losses.
