Consider the chemical equations shown he C(s) + 2H,(g) CHa(g)
C(s) + 2Cl,(g) - CCla(g)
H2(g) + Cl,(g) -- 2HCl(g)

what is the overall equation for the reaction that produces CCl4 and HCI from CH4 and Cl2?

ANSWER: 2nd option for edge ~CH4(g)+ 4CL2(g) ->CCl4(g)+ HCl(g)~

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
