Whenever quantities of two or more reactants are given in a stoichiometric problem, you must identify the __________. This is th

e reagent that is completely up in the reaction.
The amount of limiting reagent determines the amount of __________ that is formed. When an equation is used to calculate the amount of product that will form during a reaction, the value obtained is the __________. This is the amount of product that could be formed from a given amount of__________. The amount of product that forms when the reaction is carried out in the laboratory is called the __________.

Answer:

1. Limiting reactant.

2. Product.

3. Theoretical yield.

4. Reactants.

5. Actual yield

Explanation:

1. The limiting reactant. The limiting reactant is the reagent that is completely up in the reaction.

2. Product. Product is the result obtained From a reaction and the amount of product formed is determined by the limiting reactant

3. Theoretical yield. This is the result obtained from the stoichiometry calculations.

4. Reactant. Reactant are the starting material for a chemical reaction. The amount of the reactants determines the theoretical yield (products)

5. Actual yield. This is the result obtained from the experiment carried out in the laboratory.

If .758 moles of gas occupy a volume of 80.6L, how many moles will occupy a volume of 270.9L?
egoroff_w [7]

Answer:

n₂ = 2.55 mol

Explanation:

Given data:

Initial number of moles = 0.758 mol

Initial volume = 80.6 L

Final volume = 270.9 L

Final number of moles = ?

Solution:

Formula:

V₁/n₁ = V₂/n₂

V₁ = Initial volume

n₁ = initial number of moles

V₂ = Final volume

n₂ =  Final number of moles

now we will put the values in formula.

V₁/n₁ = V₂/n₂

80.6 L / 0.758 mol = 270.9 L/ n₂

n₂ = 270.9 L× 0.758 mol / 80.6 L

n₂ =  205.34 L.mol /80.6 L

n₂ = 2.55 mol

What is the ph of a solution with a hydroxide (oh) concentration of 2.02e-5?
Olegator [25]

Answer:

The solution has a pH value of 9.3.

Explanation:

To solve this problem, we can first determine the H+ ion concentration and then use this value to calculate the pH. To find the H+ ion concentration from the OH- ion concentration, we should use Kw, which we know has a value of 1 * 10^(-14).

We can then use the following formula to solve for [H+]:

Kw = [H+][OH-]

10^(-14) = (2.02 * 10^(-5)) * [H+]

[H+] = 4.950495 * 10^(-10)

Now, we can find the pH using the formula pH = -log[H+].

pH = - log[H+]

pH = - log(4.950495 * 10^(-10))

pH = 9.3

Therefore, the correct answer is that the pH of the solution is 9.3. Note that an alternative way to solve the problem is to find the pOH from the OH- ion concentration and use the resulting value to determine the pH that way instead.

Hope this helps!
