Chlorine is prepaired in the kaboratory by treating manganese dioxide

1.	Chlorine is prepaired in the kaboratory by treating manganese dioxide (Mno2) with aqueous hydrochloric acid according to the reaction4HCl (aq) +Mno2 (s) -> 2H2O +MnCl2 + Cl2how many grams of HCl react with 5 gm of manganese dioxide
Answer» Answer: 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 MANGANESE dioxide.

Answer»

Answer:

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

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 MANGANESE dioxide.
