What is the molarity of a solution where one mole of NaOH is added to 2000mL of water

Answers

Answer:

Molarity of a solution where one mole of NaOH is added to 2000mL of water is 0.0005

Explanation:

Molarity is the equal to number of moles of solute divided by total volume of solvent

Given -

Number of moles of solute i.e NaOH = 1

Total volume of solvent i.e water = 2000 mL

What is the purpose of a buffer?

Answers

The main purpose of a buffer solution is just to resist the change in pH so that the pH of the solution won't be much affected when we add an acid or base into it. The added acid or base is neutralized.

Answer: A buffer solution is a solution made to prevent the pH level of something from changing when you add a base or an acid to it. For example, if you put a buffer solution in a pool, and then you put chlorine in it, the chlorine's effect on the PH level will be suppressed.

A gas made up of homonuclear diatomic molecules escapes through a pinhole 3.98 times as fast as oxygen gas. Write the Chemical formula of the gas.

Answers

Answer:

H₂

Explanation:

To solve this question we must find, as first, find the molar mass of the homonuclear diatomic gas using Graham's law. With the molar mass we can identify this gas

Graham's law:

[tex]\frac{V_a}{V_b} =\sqrt{\frac{m_B}{m_A} }[/tex]

Where V is the speed of the gases and m the molar mass of those:

As Va is 3.98 times Vb (And mB is molar mass of oxygen gas = 32g/mol)

[tex]3.98 =\sqrt{\frac{32g/mol}{m_A} }[/tex]

15.84 = 32g/mol / mA

mA = 2.02g/mol

As is a homonuclear diatomic gas, the molar mass of the atom is 1.01g/mol. Thus, the gas is:

H₂

9.49.8 grams of Kl is dissolved in 1.00 kg of solvent. What is the molality?

Answers

Answer:

Molality = 9.498 mol k g − 1

Explanation:

A final way to express the concentration of a solution is by its molality. The molality ( m ) of a solution is the moles of solute divided by the kilograms of solvent. A solution that contains 1.0 mol of NaCl dissolved into 1.0 kg of water is a “one-molal” solution of sodium chloride.

molality = number of moles of solute/ mass of solvent in kg

number of moles of KI = mass of KI / molar mass of KI

number of moles of KI = 9.49.8 g / 1.00 g m o l − 1

number of moles of KI = 9.498 moles

molality = 9.498 moles / 1kg

molality = 9.498 mol k g − 1

A gas is heated from 263.0 K to 298.0 K and the volume is increased from 24.0 liters to 35.0 liters by moving a large piston within a cylinder. If the original pressure was 1.00 atm, what would the final pressure be?

Answers

Answer:

The final pressure is approximately 0.78 atm

Explanation:

The original temperature of the gas, T₁ = 263.0 K

The final temperature of the gas, T₂ = 298.0 K

The original volume of the gas, V₁ = 24.0 liters

The final volume of the gas, V₂ = 35.0 liters

The original pressure of the gas, P₁ = 1.00 atm

Let P₂ represent the final pressure, we get;

[tex]\dfrac{P_1 \cdot V_1}{T_1} = \dfrac{P_2 \cdot V_2}{T_2}[/tex]

[tex]P_2 = \dfrac{P_1 \cdot V_1 \cdot T_2}{T_1 \cdot V_2}[/tex]

[tex]P_2 = \dfrac{1 \times 24.0 \times 298}{263.0 \times 35.0} = 0.776969038566[/tex]

∴ The final pressure P₂ ≈ 0.78 atm.

How much so you can be dissolved and 50 mL of water at 30 Celsius see chart:)

Answers

Answer:

The correct answer is - 100 grams.

Explanation:

The solubility graph is a very useful tool because it tells you the amount of solute that can be dissolved per 100 mL of water in order to have a saturated solution of potassium nitrate at a given temperature.

In order to find the solubility of the salt at 30 ∘ C , start from the 30 ∘ C

mark on the graph and move up until you intersect the curve. At the point of intersection, move left until you intersect the y axis and read off the value that you land on which is 200. However, it is for 100 ml so half the value you read:

200/2 = 100 gram .

So, solubility ≈ 100 g / 50 mL water

So, a saturated solution of solute will hold about 100 g of dissolved solute, that is of dissociated solute, per 50 mL of water at 30 ∘ C .

What is the systematic name of the following compound?
CaF 2

Answers

This is a binary ionic compound (an ionic compound consisting of two elements). The stock method of naming ionic compounds can be applied here.

First, identify and name the cation (the positive ion): Here, that would be the calcium (Ca2+) ion.

Next, identify and name the anion (the negative ion). Here, that would be the fluoride ion (F-). The anionic form of an element’s name can often be obtained by retaining the root and replacing the ending with -ide (e.g., sulfur becomes sulfide; oxygen becomes oxide; nitrogen becomes nitride; chlorine becomes chloride; bromine becomes bromide; etc.).

So the systematic name of CaF2 would be calcium fluoride.

What effect does an increase in carbon dioxide (CO 2 ) have on the concentration of hydrogen ions (H^ + ) in the blood?

Answers

Answer:

As the level of carbon dioxide in the blood increases, more H+ is produced and the pH decreases. This increase in carbon dioxide and subsequent decrease in pH reduce the affinity of hemoglobin for oxygen. The oxygen dissociates from the Hb molecule, shifting the oxygen dissociation curve to the right.
