Answer:

Volume of HBr = V₂ = 7.5 mL

Explanation:

Given data:

Volume of NaOH =V₁= 25.0 mL

Molarity of NaOH =M₁= 0.150 M

Molarity of HBr =M₂= 0.5 M

Volume of HBr =V₂= ?

Solution:

M₁V₁ = M₂V₂

0.150 M ×25.0 mL = 0.5 M×V₂

V₂ = 0.150 M ×25.0 mL / 0.5 M

V₂ = 3.75 M.mL /0.5 M

V₂ = 7.5 mL

Question 2 the osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the ga

Nutka1998 [239]

1) osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant r.

Call: P = osmotic pressure; C = molarity; T = absolute temperature

=> P = C * T * r

2) write an equation that will let you calculate the molarity c of this solution. your equation should contain only symbols. be sure you define each symbol other than r. 

=> C = P / (rT)

Answer: C = P / (rT)

Write a balanced chemical equation for this reaction. What is the coefficient for hydrochloric acid in the reaction

Leviafan [203]

The question is incomplete, here is the complete question:

Write a balanced equation for the neutralization of calcium hydroxide by hydrochloric acid. What is the coefficient for hydrochloric acid in the reaction.

Answer: The balanced chemical reaction is written below and the coefficient of hydrochloric acid is 2.

Explanation:

Neutralization reaction is defined as the reaction in which an acid reacts with a base to produce a salt and water molecule.

Balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side will be equal to the total number of individual atoms on the product side. These equations follow law of conservation of mass.

The balanced chemical equation for the reaction of calcium hydroxide and hydrochloric acid follows:

$Ca(OH)_2+2HCl\rightarrow CaCl_2+2H_2O$

By Stoichiometry of the reaction:

1 mole of calcium hydroxide reacts with 2 moles of hydrochloric acid to produce 1 mole of calcium chloride and 2 moles of water molecule.

Hence, the balanced chemical reaction is written below and the coefficient of hydrochloric acid is 2.
