Explanation:

Before it can be used in a reactor for electricity generation, however, it must undergo a series of processes to produce a useable fuel. For most of the world's reactors, the next step in making the fuel is to convert the uranium oxide into a gas, uranium hexafluoride (UF6), which enables it to be enriched.

Match these items. 1. moles per liter of solution solute 2. spreading out Keq 3. substance being dissolved diffusion 4. general

Degger [83]

Answer:

1. moles per liter of solution - Molarity

2. spreading out - diffusion

3. substance being dissolved- solute

4. general equilibrium constant - Keq

5. the substance doing the dissolving in a solution - solvent

6. solubility product constant - Ksp

Explanation:

Number of moles of substance being dissolved in one liter of solution is defined as molarity

Solute is the substance which is dissolved and solvent is the substance into which the solute is dissolved. For example salt is solute and water is solvent.

Ksp defines the solubility product constant which indicates the equilibrium between a solid and solution and the number of ions of solid required to achieve this equilibrium.

Keq depicts the scenario where reactant and product concentrations are constant in a chemical reaction.

Hence, the correct match is

1. moles per liter of solution - Molarity

2. spreading out - diffusion

3. substance being dissolved- solute

4. general equilibrium constant - Keq

5. the substance doing the dissolving in a solution - solvent

6. solubility product constant - Ksp

What is the mass of 8.00 moles of sodium chloride

Korolek [52]

N(NaCl)=8 moles

M(NaCl)=A(Na)+A(Cl)
M(NaCl)=22.99+35.45=58.44 g/moles

m(NaCl)=n(NaCl)·M(NaCl)
m(NaCl)=8moles·58.44g/moles=467.52 g

Volume of 0.150 M NaOH solution required to neutralize 25mL of a 0.055 M HCl solution?

Inessa05 [86]

<h3>Answer:</h3>

9.17 mL

<h3>Explanation:</h3>

In this question<u> we are given;</u>

Molarity of NaOH as 0.150 M
Molarity of the acid, HCl as 0.055 M
Volume of the acid, HCl as 25 mL
Equation for the reaction as;

NaOH(aq) + HCl(aq) → H2O(l) + NaCl(aq)

We are required to determine the volume of the alkali, NaOH used;

<h3>Step 1: Determine the moles of the acid, HCl</h3>

Molarity = Number of moles ÷ Volume

Thus, rearranging the formula;

Moles = Molarity × volume

= 0.055 M × 0.025 L

= 0.001375 moles

<h3>Step 2: Moles of the alkali, NaOH</h3>

From the reaction; 1 mole of HCl reacts with 1 mole of NaOH

Therefore;

Moles of HCl = Moles of NaOH

Hence; Moles of NaOH = 0.001375 moles

<h3>Step 3: Determine the volume of the alkali, NaOH</h3>

From the previous equation;

Molarity = Moles ÷ Volume

Rearranging the equation;

Volume = Moles ÷ Molarity

Therefore;

Volume of NaOH = 0.001375 moles ÷ 0.150 M

= 0.00917 L, but, 1 L = 1000 mL

= 9.17 mL

Therefore, the volume of NaOH required is 9.17 mL
