Question

one of the substances that are harmful to Earth's ozone layer is the chlorofluorocarbon C2F5Cl. This gas breaks down into carbon dioxide and its constituent halogens when exposed to oxygen. A researcher completely reacts 5.35g of C2F5Cl in excess oxygen gas at STP.
Afterward, the gases that are produced are separated into separate containers, and the mass of each gas is measured. The researcher claims that chlorine gas is in one of the containers. What must the mass, in grams, of the gas in that container be in order to justify this claim?

What equation do I start with? C2F5Cl --> CO2+?

Answer 1

@Abmon98

Answer 2

gas breaks down when exposed to oxygen to its constituent halogens which are fluorine and chlorine.
2C2F5Cl+O2-->4CO2+Cl2+5F2

Answer 3

do i find moles of C2F5Cl from the grams, use my mol ratio for Cl2 on the other side, and then find grams? @Abmon98

Answer 4

yes you find the number of moles of C2F5Cl

Answer 5

isn't it 2:1?

Answer 6

C2F5Cl+2O2-->2CO2+Cl+F5
that's the balanced chemical equation

Answer 7

I got 2.48gCl2 according to that equation.

Answer 8

work with this balanced chemical so you first find the number of moles using Number of Moles=Mass(g)/Molar Mass(g/mol)
Mole ratio of C2H5Cl and Cl
Atomic Weight of Cl:35.5 use Mass(g)=Number of Moles*Molar Mass(g/mol)

Answer 9

oh it's not cl2? isn't it gaseous?

Answer 10

Cl is a diatomic

Answer 11

ohhhh

Answer 12

so it'd be half of my last answer, 1.24gCl

Answer 13

no wait dsood15 i think its related to radicals thats why its Cl

Answer 14

@asib1214 what do you think?
