The answer is $2Fe_2O_3 + 3C -> 3Fe + 3CO_2$

You must make sure each reactant has the same amount of subscripts on both sides of the equation.

Answer:

2Fe₂O₃ + 3C → 4Fe + 3CO₂

Explanation:

An equation is said to be balanced if there are equal number of atoms of one type on the reactants as well as the product side. The given equation is:

Fe₂O₃ + C → Fe + CO₂

# Reactants # Products

Fe = 2 Fe = 1

O = 3 O = 2

C = 1 C = 1

The equation is not balanced as there are different number of atoms of Fe and O on either side. In order to balance it, multiply Fe2O3 by 2, C by 3, Fe by 4 and CO2 by 3 to get:

2Fe₂O₃ + 3C → 4Fe + 3CO₂

746mmHg, 115m^3, 21*C number of moles?

victus00 [196]

Answer:

n = 4678.13 mol

Explanation:

Given data:

Temperature = 21°C

Pressure = 746 mmHg

Volume = 115 m³

Number of moles = ?

Solution:

21+273 = 294 k

746 /760 = 0.982 atm

115×1000 = 115000 L

PV = nRT

n = PV/RT

n = 0.982 atm × 115000 L /0.0821 atm. L. K⁻¹. mol ⁻¹× 294 k

n = 112930 atm. L/24.14 atm. L. mol ⁻¹

n = 4678.13 mol

2C2H2(g) 5O2(g) → 4CO2(g) 2H2O(g) This is a balanced equation for the combustion of acetylene(C2H2). How many moles of oxygen(O2

omeli [17]

The moles of oxygen required to completely react with 1-mole acetylene is 2.5 mol.

The moles of reactant and product in a chemical reaction to the whole number ratio is given by the stoichiometric coefficient of the balanced chemical equation.

<h3>Computation for the moles of oxygen</h3>

The balanced chemical equation for the reaction is :

$\rm 2\;C_2H_2\;+\;5\;O_2\;\to\;4\;CO_2\;+\;2\;H_2O$

From the balanced chemical equation, the 2 moles of acetylene react with 5 moles of oxygen.

The moles of oxygen react with 1 mole of acetylene are:

$\rm 2\;mol\;C_H_2=5\;mol\;O_2\\\\1\;mol\;C_2H_2=\dfrac{5}{2}\;\times\;1\;mol\;O_2\\\\ 1\;mol\;C_2H_2=2.5\;mol\;O_2$

The moles of oxygen required to completely react with 1-mole acetylene is 2.5 mol.
