How many moles of co2 are produced when 35.0 mol c2h2 react completely?
Setler [38]

The balanced chemical reaction will be:

C2H2 + 3/2O2 = 2CO2 +H2O

We are given the amount of C2H2 to be burned. This will be our starting point.

<span>35.0 mol C2H2 ( 2 mol CO2/1 mol C2H2) = 70.0 mol O2</span>

<span>Therefore, the CO2 produced is 70.0 moles.</span>

jarptica [38.1K]

Answer:

coefficient 3 is needed t with water molecule to balance the equation.

Explanation:

Chemical equation:

Fe₂O₃ + H₂SO₄ →  Fe₂(SO₄)₃ + H₂O

Balanced chemical equation:

Fe₂O₃ + 3H₂SO₄ →  Fe₂(SO₄)₃ + 3H₂O

The equation is balanced. There are two iron three sulfate six hydrogen and three oxygen atoms are present on both side of equation.

The given equation completely follow the law of conservation of mass.

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Coefficient with reactant and product:

Fe₂O₃             1

H₂SO₄             3

Fe₂(SO₄)₃        1

H₂O                 3

So coefficient 3 is needed t with water molecule to balance the equation.
