aseous methane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 5.5 g of methane is mixed with 13.9 g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. Round your answer to significant digits.

Answers

Answer:

There is 9.6 grams of CO2 produced

Explanation:

Step 1: Data given

Mass of methane = 5.50 grams

Molar mass of methane = 16.04 g/mol

Mass of oxygen = 13.9 grams

Molar mass of oxygen = 32.0 g/mol

Step 2: The reaction

CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)

Step 3: Calculate number of moles

Moles = mass / molar mass

Moles methane = 5.50 grams / 16.04 g/mol

Moles methane = 0.343 moles

Moles oxygen = 13.9 grams / 32.0 g/mol

Moles oxygen = 0.434 moles

For 1 mol CH4 we need 2 moles O2 to produce 1 mol CO2 and 2 moles H2O

O2 is the limiting reactant. It will completely react (0.434 moles).

There will react 0.434/2 = 0.217 moles CH4

There will remain 0.343-0.217 = 0.126 moles CH4

There will be produced 0.434 moles of H2O and

0.434/2 =0.217 moles of CO2

Step 4: Calculate mass of products

Mass = moles * molar mass

Mass CO2 = 0.217 moles ¨44.01 g/mol

Mass CO2 = 9.6 grams

Mass H2O = 0.434 moles * 18.02

Mass H2O = 7.8 grams

why atoms of magnet differ from normal atoms?


Copied answers ❌❌❌​

Answers

Answer:

The magnetic field of an atom, say H (one electron revolving around a proton) is composed of two separate contributions: an orbital magnetic moment and a spin magnetic moment. We get magnetic moments because of electromagnetic induction associated with each type of electron motion. The electron revolving around the proton with a certain angular momentum is related to the associated orbital magnetic moment (and, yes, we model it as a wire loop with current expressed in terms of the orbital velocity). This can be calculated using elementary mechanics. The spin magnetic moment is a little trickier because it is caused by the intrinsic spin of the electron which is a quantum phenomenon; therefore, this spin magnetic moment can only be calculated using quantum mechanics. In the end, we get a certain net magnetic moment associated with this motion of the electron in an atom. It is important to notice that this atom acts as a magnetic dipole (remember, as of yet, magnetic monopoles don't exist!).

If we take a bulk magnet like you might have on your fridge, it would be composed of atoms. Each atom operates as a magnetic dipole, but due to internal atomic structures, the atoms actually align themselves into separate magnetic domains, each with a net magnetic moment (caused my individually adding up those atomic dipole moments). In a common magnet (ferromagnet), these domains all point the same direction and stay that way, creating a permanent bulk magnetic dipole.

So in a way, there is no difference between the magnetic field of an atom and that of a magnet because one is simply a sum of the other, making both magnetic dipoles. Of course, here we see that there's nothing that fundamental about the magnetic force. In reality, the magnetic force is a relativistic effect caused by the movement of a charged particle, making electricity (i.e. charge) the underlying property at work here. Electromagnetic induction is really a shortcut to understand the magnetic force without worrying about relativistic mechanics. If we were to discover magnetic monopoles (i.e. "magnetic" charge), this would re-write a lot that we know about electromagnetism because we couldn't label all magnetic forces as by-products of moving electric charge

which organ is used to detect the product of neutralisation reaction

Answers

Answer:

Neutralization reactions occur when two reactants, an acid and a base, combine to form the products salt and water.

The organ that is used to detect the product of a neutralization reaction is the sense of taste.

When a neutralization reaction occurs between an acid and a base, it results in the formation of a salt and water. The salt produced in the reaction may have a distinct taste, depending on its chemical properties. For example, when hydrochloric acid reacts with sodium hydroxide, the products are sodium chloride and water. Sodium chloride, commonly known as table salt, has a characteristic salty taste.

Similarly, other salts formed from neutralization reactions may have different tastes. For instance, magnesium hydroxide reacting with acetic acid produces magnesium acetate, which has a slightly sweet taste. By using our taste buds, particularly on the tongue, we can detect and identify the taste of the salt formed during a neutralization reaction.

C₂H₄O₂ + O₂ ➞ CO₂ + H₂O

Answers

Answer:

C2H4O2 + 2O2 ==> 2CO2 + 2H2O

Explanation:

Start with the carbons

C2H4O2 + O2 ==> 2CO2 + H2O There are 2 on the left, so you need 2 on the right.

Next deal with the hydrogens. You have 4 on the left so you have to make 4 on the right

C2H4O2 + O2 ==> 2CO2 + 2H2O

The oxygens are the real devil in this question. Be careful how you handle them. There are 2 * 2 = 4 from the CO2 and 2*1 = 2 from the water. The total is 6

Now you can't just put a 3 in front of the O2. There are 2 in the given chemical. So you don't need 6. You need 6 -2 = 4. But the oxygen is O2. You have to divide the 4 by 2 to get 2

C2H4O2 + 2O2 ==> 2CO2 + 2H2O

How many grams of ammonia can be produced from reacting a 450 L sample of nitrogen gas at a temperature of 450 K and a pressure of 300 atm?

Answers

Answer: A mass of 124457.96 g ammonia is produced by reacting a 450 L sample of nitrogen gas at a temperature of 450 K and a pressure of 300 atm.

Explanation:

Given: Volume = 450 L

Temperature = 450 K

Pressure = 300 atm

Using ideal gas equation, moles of nitrogen are calculated as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = tempertaure

Substitute values into the above formula as follows.

[tex]PV = nRT\\300 atm \times 450 L = n \times 0.0821 L atm/mol K \times 450 K\\n = \frac{135000}{36.945}\\= 3654.08 mol[/tex]

According to the given equation, 1 mole of nitrogen forms 2 moles of ammonia. So, moles of ammonia formed by 3654.08 moles of nitrogen is as follows.

[tex]2 \times 3654.08 mol\\= 7308.16 mol[/tex]

As moles is the mass of substance divided by its molar mass. So, mass of ammonia (molar mass = 17.03 g/mol) is as follows.

[tex]Moles = \frac{mass}{molar mass}\\7308.16 = \frac{mass}{17.03 g/mol}\\mass = 124457.96 g[/tex]

Thus, we can conclude that a mass of 124457.96 g ammonia is produced by reacting a 450 L sample of nitrogen gas at a temperature of 450 K and a pressure of 300 atm.

As electrons are passed down the electron transport chain, the molecules are first ______ as they pick up electrons, and then ______ as they release the electrons.

Answers

Answer:

reduced; oxidized

Explanation:

An electron transport chain can be defined as a series of redox reactions (electron transporters or proton complexes) that are saddled with the responsibility of transferring electrons from electron donors to electron acceptors through a membrane in order to produce a protein gradient that creates energy or adenosine triphosphate (ATP).

Generally, as these electrons are transferred through the electron transport chain, the molecules are first reduced as they pick up electrons, and then oxidized as they release the electrons.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

Prove that:-
1.The unit of pressure is a derived unit?
2.The unit of work is a derived?​

Answers

Answer:01

When you describe nature, and you need standard, useful units for everything you will see that these units are linked. So you start with defining base units that are simple:

kg, meter, second, Kelvin, …

Now other units will be automatically derived:

speed = distancetime , so the unit is  ms  

acceleration =  speedincreasetime , so the unit is  ms2  

Force = Mass x acceleration, so the unit is  kg.ms2  

Pressure is Force/surface, so the unit is  kgm.s2  

You can define new simple units for this, but they are still derived from the base units:

Force:  1N=1kg.ms2  

Pressure:  1Pa=1kgm.s2

2 Answer

In mechanics, work is defined as “force x distance”. Since energy can be measured as work, we can write energy = force x distance. Thus SI derived unit of energy has the units of newtons x meter or kg m2/s

Sodium lauryl sulfate and ammonium lauryl sulfate are surfactants that help with the mixing of oil and water. As such, they can clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away or suspend poorly soluble ingredients in water.

Safety Information:

The U.S. Food and Drug Administration (FDA) includes sodium lauryl sulfate on its list of multipurpose additives allowed to be directly added to food. Sodium lauryl sulfate and ammonium lauryl sulfate are also approved indirect food additives. For example, both ingredients are permitted to be used as components of coatings.

The safety of sodium lauryl sulfate and ammonium lauryl sulfate has been assessed by the Cosmetic Ingredient Review  (CIR) Expert Panel on two separate occasions (1983 and 2002), concluding each time that the data showed these ingredients were safe in formulations designed for brief, discontinuous use, followed by thorough rinsing from the surface of the skin. In products intended for prolonged contact with skin, concentrations should not exceed 1%.
