The correct balance is
CaO + 3C→CaC2 + CO
This happens to be a famous reaction from way back in the late 1800's. Limestone (CaO) was reacted with coke (C) with huge amounts of electricity to form calcium carbide.
When you add water to calcium carbide you get acetylene. This is how the organic chemicals industry started in the late 1800's and how acetylene was made for lighting and torches.

stability the equation.. 2CaO + 5C = 2CaC2 + CO2 Use stoichiometry. CaO: 50.0g/fifty six.1g * 2mol CaC2/2mol CaO * sixty 4.1g CaC2/1mol = fifty seven.1g CaC2 C: 50.0g/12.0g * 2mol CaC2/5mol C * sixty 4.1g CaC2/1mol = 106.8g CaC2 The C is the limiting reactant. by making use of POE, c, d, e won't be able to be limiting reactants given the equation, and because CaO is a compound, it is going to frequently be the limiting reactant while an ingredient is interior the equation.
