Question

Chlorine are required to completely react with 0.40 gram of hydrogen to form hydrochloric acid also calculate the amount of hydrochloric acid formed

Answer 1

0,40/100 ==40/10000

=0.004grams

hence 0.004grams is amount of him formed

Answer 2

may be it's a nice answer for you,

The reaction is as follow:

H2 + Cl2---------> 2HCl

The mole ratio is 1:1:2

Moles of 0.4g hydrogen.... moles = mass/molar mass 0.4/2=0.2 moles

mole ratio is 1:1,the the moles of chlorine required will be 0.2 moles

mass of chlorine required

mass= moles x molar mass.....moles=0.2 molar mass= 35.5

mass=0.2 x 35.5

= 7.1 g

Mass of Hcl formed

Since mole ratio H2: HCl = 1:2

Moles of H2 is 0.2moles , hence moles of HCl = 0.4 moles

Molar mass of HCl = 36.5 (mass = moles x molar mass)

mass= 0.4 x 36.5

= 14.6g

Mass of chlorine formed= 14.6 grams
