Question

for a reaction calculate mass of hydrochloric acid needed to react with manganese dioxide MnO2 4 HCl + MnO2 --- 2H2O + MnCl2 + Cl2​

Answer 1

Answer:

8.39 grams of Hcl would react with 5 gm of MnO2. 4HCl + MnO2 ----> 2H2O + MnCl2+ Cl2. for this reaction determine the mass of HCl that will react with 5 gm of MnO2. MnO2 = 54.94 + 2 ( 15.99 ) = 86.92 g of MnO2.
