The titration of an acid (H2A) with LiOH solution generates the following titration curve. What are the main components (more than half of the initial amount of H2A, besides H2O) at equivalence point 1 (EP1) and equivalence point 2 (EP2)? Main Components at EP1 Main Components at EP2
A H2A and OH− A2− and OH−
B HA− and Li+ A2− and Li+
C HA− and OH− HA− and Li+
D H2A and Li+ HA− and OH−

Answers

The main components (more than half of the initial amount of H2A, besides H2O) at equivalence point 1 and 2 (EP1), (EP2) is HA⁻ and Li⁺ A²⁻ and Li⁺.

What is the Titration curve?

Titration of acid H₂A with LiOH solution.

At first equivalent points are:

H₂A + LiOH → HA⁻ + Li⁺ + H₂O

The Main component at (EP1) => HA⁻ and Li⁺

At second equivalence point are:

HA⁻ + LiOH → A²⁻ + Li⁺ + H₂O

Main component at (EP2) => A²⁻ and Li⁺

Therefore, the correct option is B which is HA− and Li+ A2− and Li+

Answer:

B) HA⁻ and Li⁺ A²⁻ and Li⁺

Explanation:

Titration of acid H₂A with LiOH solution.

At first equivalent point

H₂A + LiOH → HA⁻ + Li⁺ + H₂O

Main component at (EP1) => HA⁻ and Li⁺

At second equivalence point

HA⁻ + LiOH → A²⁻ + Li⁺ + H₂O

Main component at (EP2) => A²⁻ and Li⁺

Therefore, the correct answer is B

A particular refrigerant cools by evaporating liquefied CCl 2F 2. How many kg of the liquid must be evaporated to freeze a tray of water to ice (at zero degrees C)? The tray contains 525 grams water. Molar heat of fusion of ice = 6.01 kJ/mol. Molar heat of vaporization of CCl 2F 2 = 17.4 kJ/mole

Answers

Answer : The mass of $CCl_2F_2$ evaporated must be, 1.217 kg

Explanation :

First we have to calculate the moles of water.

$\text{Moles of water}=\frac{\text{Mass of water}}{\text{Molar mass of water}}$

Molar mass of water = 18 g/mol

$\text{Moles of water}=(525g)/(18g/mol)=29.17mol$

Now we have to calculate the heat released.

Heat released = Moles of water × Molar heat of fusion of ice

Heat released = 29.17 mol × 6.01 kJ/mol

Heat released = 175.3 kJ

Now we have to calculate the moles of $CCl_2F_2$

Heat = Moles of $CCl_2F_2$ × Molar heat of vaporization of $CCl_2F_2$

175.3 kJ = Moles of $CCl_2F_2$ × 17.4 kJ/mol

Moles of $CCl_2F_2$ = 10.07 mol

Now we have to calculate the mass of $CCl_2F_2$

$\text{Mass of }CCl_2F_2=\text{Moles of }CCl_2F_2* \text{Molar mass of }CCl_2F_2$

Molar mass of $CCl_2F_2$ = 120.9 g/mol

$\text{Mass of }CCl_2F_2=10.07mol* 120.9g/mol=1217.463g=1.217kg$

Thus, the mass of $CCl_2F_2$ evaporated must be, 1.217 kg

If sodium arsenite is Na3AsO3, the formula for calcium arsenite would be

Answers

Answer:

Ca₃(AsO₃)₂

Explanation:

Sodium arsenite, with the chemical formula Na₃AsO₃, is formed by the cation Na⁺ and the anion AsO₃³⁻. For the molecule to be neutral, 3 cations Na⁺ and 1 anion AsO₃³⁻ are required.

Calcium arsenite would be formed by the cation Ca²⁺ and the anion AsO₃³⁻. For the molecule to be neutral, we require 3 cations Ca²⁺ and 2 anions AsO₃³⁻. The resulting chemical formula is Ca₃(AsO₃)₂.

A student was asked to prepare exactly 250 mL of a 0.500 M aqueous potassium hydroxide solution. What mass of potassium hydroxide (molar mass = 56.10 g/mol) must the student dissolve in the 250 mL of solution? 1. 28.1 g 2. 3.0 g 3. None of these 4. 14.0 g 5. 7.01 g 6. 56.1 g

Answers

Answer:

Option 5 → 7.01 g

Explanation:

Molarity . volume (L) = Moles

This can help us to determine the moles of KOH that are in the solution.

We convert the volume from mL to L → 250 mL . 1L / 1000mL = 0.250 L

0.5 mol /L . 0.250L = 0.125 moles of KOH

Now, we only have to convert the moles to mass, by the molar mass:

Moles . molar mass = mass → 0.125 mol . 56.1 g/mol = 7.01 g

Answer:

We need 7.01 grams of KOH (option 5)

Explanation:

Step 1: Data given

Volume aqueous KOH solution = 250 mL = 0.250 L

Molarity = 0.500 M

Molar mass of KOH = 56.10 g/mol

Step 2: Calculate moles KOH

Moles KOH = molarity * volume

Moles KOH = 0.500 M * 0.250 L

Moles KOH = 0.125 moles

Step 3: Calculate mass of KOH

Mass KOH = moles KOH * molar mass KOH

Mass KOH = 0.125 moles * 56.10 g/mol

Mass KOH = 7.01 grams

We need 7.01 grams of KOH
