Question

Show the following equation are in accordance with the law of conversion of mass

(Fe=56;S=32,H=1,Cl=35.5)

1.Fe +S →FeS
2.H2 +Cl2→2HCI


in second question in reactants 2 will be down

Answer 1

1.fe +s =fes

56+32=88

2...h2+cl2=2hcl

(1×1)+2(1×35.5)

=(2)+2(35.5)

=39.5

Answer 2

Answer:

fe + s = feS

mass of iron =56g

mass of sulphur =32g

total mass of reactants =56+32=88g

mass of iron sulphide =56+32=88g

i.e.total mass of reactants=total mass of product.

thus it is in accordance with conversation of mass
