Question

Chloride is prepared in laboratory by treating manganese dioxide with aqueous hydrochloric acid according to the reaction how many gram of hcl react with 4Hcl + Mno2 => 2H2o + Mncl2 + cl2 how many grams of HCL reacts with 5.0 g of manganese dioxide

Answer 1

Answer:

According to the given equation:

MnO 2  +4HCl→MnCl 2  +Cl 2  +2H 2 O  

1 mole of MnO2 reacts with 4 mole of HCl

or 87 g MnO2  reacts with 146 g HCl

​∴ 5 g MnO2 Will react with  146 /87 ×5gHCl=8.39HCl
