How many moles of CO2 are produced when 2.5 moles of O2 react according to the following equation? C3H8 + 5O2 ? 2FeO + 3SO2

1.5 moles of CO₂ are produced

Explanation:

Based on the chemical equation:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O -The reaction of the question is wrong-

5 moles of oxygen reacts per mole of propane, C₃H₈, to produce 3 moles of CO₂ and 4 moles of water.

If 2.5 moles of oxygen react and, 5 moles of oxygen produce 3 moles of CO₂, moles of CO₂ produced are:

2.5 moles O₂ * (3 moles CO₂ / 5 moles O₂) =

a) the particles of the chair are strongly held together.

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
