Carbon disulfide is an important industrial solvent. it is prepared by the reaction of coke with sulfur dioxide. 5c(s)+2so2(g)-> cs2(l)+ 4co(g)

I added a screenshot with the complete question.

Part (a):
The balanced equation given is:
5C(s) + 2SO₂(g) ........> CS₂(l) + 4CO(g)From this equation, we can note that 5 moles of C are required to form 1 mole of CS₂. Therefore, to know the number of moles formed from 2.7 moles of C, we will use cross multiplication as follows:
5 moles of C ..............> 1 mole of CS₂
2.7 moles of C ............> ?? moles of CS₂
number of moles of CS₂ = (2.7*1) / 5 = 0.54 moles

Part (b):
The balanced equation given is:
5C(s) + 2SO₂(g) ........> CS₂(l) + 4CO(g)From this equation, we can note that 5 moles of C are required to react with 2 mole of SO₂. Therefore, to know the number of moles of carbon needed to react with 5.44 moles of SO₂, we will use cross multiplication as follows:
5 moles of C ..............> 2 mole of SO₂
?? moles of C ............> 5.44 moles of SO₂
number of moles of SO₂ = (5.44*5) / 2 = 13.6 moles

Part (c):
The balanced equation given is:
5C(s) + 2SO₂(g) ........> CS₂(l) + 4CO(g)From this equation, we can note that 4 moles of CO are formed when 1 mole of CS₂ is formed. Therefore, to know the number of CO moles formed from 0.246 moles of CS₂, we will use cross multiplication as follows:
4 moles of CO ..............> 1 mole of CS₂
?? moles of CO ............> 0.246 moles of CS₂
number of moles of CS₂ = (0.246*4) / 1 = 0.984 moles

Part (d):
The balanced equation given is:
5C(s) + 2SO₂(g) ........> CS₂(l) + 4CO(g)From this equation, we can note that 2 moles of SO₂ are required to form 1 mole of CS₂ is formed. Therefore, to know the number of SO₂ moles required to form 118 moles of CS₂, we will use cross multiplication as follows:
2 moles of SO₂ ..............> 1 mole of CS₂
?? moles of SO₂ ............> 118 moles of CS₂
number of moles of SO₂ = (118*2) / 1 = 236 moles

Hope this helps :)

Iread all the questions and answers, that person done a lot of work so go ahead and give them brainliest!
