Question

Calculate mass of 90% pure mno2 to produce 35.5gm of cl2

Answer 1

Answer:

Explanation:

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.

Mass of

MnO2 = 54.94 + 2 ( 15.99 ) = 86.92 g of MnO2.

Mass of

Hcl = 1.01 + 35.45 = 36.46 g of Hcl.

= 4 mole of Hcl

1 mole of Mno2.

= ( 5.00) (4) ( 36.46) / 86.92

= 8.39 g of Hcl ( proved )
