In the balanced equation , cs2 + 3o2 = co2 + 2so2 , how many mol of o2 would react with 34.5 mol of co2?

The moles of oxygen gas will react with 34.5 moles of carbon disulfide is 103.5 moles.

Explanation:

Given ,moles of carbon disulfide = 34.5 moles

According to reaction, 1 mol of carbon disulfide reacts with 3 moles of oxygen gas.

Then 34.5 moles of carbon disulfide will react with:

oxygen gas.

The moles of oxygen gas will react with 34.5 moles of carbon disulfide is 103.5 moles.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
