Answer 1

Answer:

HCl : molar mass = 36.4

Mn O2 : 54.9 + 32 = 86.9

4 moles of HCl = 145.6 grams reacts with 1 mole of Mn O2 ie., 86.9 grams..

So  mass of HCl that reacts with 5.0 grams of Manganese dioxide :

           5 * 145.6 / 86.9  = 8.377 grams of HCl.

hope it helped u ♥♥♥

Answer 2

Answer:

8.39 grams of Hcl would react with 5 gm of MnO2. 4HCl + MnO2 ----> 2H2O + MnCl2+ Cl2.
