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

Explanation:
c or d has the correct names and Roman numerals.
When it comes into contact with It will turn purple
Answer:
(A) H2CO3 = H20 + CO2
Explanation:
Carbonic acid is formed from carbon dioxide and water so its equation will be
H2CO3 → H2O + CO2
The equation is balanced as same no of atoms of each specie is present both sides
- is a natural fibre
- has low elasticity
- is wrinkle free.
