How much hydrogen chloride acid was used?
72.916 g of hydrochloric acid was used.
Given:
Mass of Zn = 65.39 g
Mass of 
=136.29 g
Mass of 
= 2 g
Equation:
The chemical equation for the reaction of zinc with hydrochloric acid:
Zn + 2HCl → Zn 
+
Hydrogen gas is created when zinc combines with hydrochloric acid, which causes the process to bubble ferociously. Another sign that a chemical reaction is taking place is the generation of a gas.
Calculation:
A number of equivalents equate:
Number of equivalents = 
x 1000 x equivalent factor
x 1000 x 1 = 
x 1000 x 2
= 36.458 x 2
= 72.916

Answer:
Atoms can gain, lose, or share electrons during a chemical change. Chemical changes do not affect the nucleus of an atom. For this reason, an atom has the ability to retain its properties or identity even if the number of electrons is different. Therefore, the atom's identity won't change.

Answer:
The final pressure is 173 kPa.
Explanation:
A mixture of gases at an initial pressure of P₁ = 101 kPa is compressed from an initial volume V₁ = 7.20 dm³ to a final volume V₂ = 4.21 dm³. If we suppose an ideal gas behavior and that temperature remains constant, we can apply Boyle's law to find out the final pressure P₂:
P₁ . V₁ = P₂ . V₂
The answer is hydrobromic acid.
That is the name for aqueous HBr is hydrobromic acid.
If there is no water that is if it is not aqueous then the name will be hydrogen bromide but as it is acid and in aqueous state so the name will be hydrobromic acid. As it is acid that's why the suffic ic is used and as it is in aqueous state, so hydro is used.
