Question

How many grams of chlorine gas is required to completely react with 0.400g of
hydrogen gas to yield hydrogen chloride gas

Answer 1

H2+Cl2-->2HCL
Number of Moles=Mass(g)/Molar Mass(g/mol)
0.400/1=0.400 moles
Mole Ratio of H2 and Cl2 is 1:1 so they share the same number of moles
Arrange the equation: Mass(g)=Molar Mass(g/mol)*Number of Moles
0.400*35.5=14.2

Answer 2

Also calculate the amount of HCl
formed?

Answer 3

Why dont you try solving it

Answer 4

cause I don't know..pls

Answer 5

Look at the mole ratio from the balanced chemical equation of H2 Cl2 and HCL
1:1:2
0.4:0.4:0.8
Mass(g)=Molar Mass(g/mol)*Number of moles
0.8*(1+35.5)=Mass
