Question

Balance the chemical equation below using the smallest possible whole number stoichiometric coefficients. C(s) + H2(g) --> C2H6(g)?

Answer 1

2C(s) + 3H2(g) --> C2H6(g)

Answer 2

Answer: 2C(s) + 3H2(g) = C2H6(g)

Step-by-step explanation:

In balancing chemical equations, the reactant must be equal to the product. I.e law of conservation of matter must hold.

2 moles of carbon would react with 3 moles of hydrogen to give 1 mole of methane

2C(s) + 3H2(g) = C2H6(g)
