The balanced reaction is:<span>
MnO2(s) + 4HCl(aq) → Cl2(g) + MnCl2(aq) + 2H2O(l)
We
are given the amount of hydrochloric acid to be used for the reaction. This
will be the starting point for the calculations.
1.82 mol
HCl ( 1 mol Cl2 / 4 mol HCl) = 0.46 mol Cl2
<span>Therefore,
0.46 mol of chlorine gas is produced for the reaction of hydrochloric acid and
manganese oxide.</span></span>
The answer is hydrogen. the first element in the periodic table.

Answer:
20cm³ of sulphuric acid reacts completely with excess zinc to form 0.1 mole of hydrogen gas. Calculate the molarity of the acid used.?
Molarity= mol/volume
Molarity= 0.1/20
Molarity= 0.005mol/L
