Question

chlorine is
prepared in laboratory
by treating MnO₂ with
aqueous
HCL according to
reaction
4HCl (aq) + MnO2 (s)
» 2H2O(l) +MnCl2
(aq)+cl2(g)

How many geams of HCl react
with 5g of mno2?
[Atomic mess C= 35.5 and mn=55u

please give answer I will mark as brainliest ​

Answer 1

Explanation:

Molecular weight of Mno2 = 87 g

Molecular weight of Hcl = 4 * 36.5 = 146 g

According to chemical reaction

1 g of Mno2 reacts with 4g of Hcl togive = 146/87 * 1

Or

5 g of Mno2 reacts with 4g of Hcl to give = 146/87 *5 = 8.4 g of Hcl

Hence, 8.4 g of HCl will react completely with 5.0 g of C

Hope it helps you
