Which set of coefficients will balance this chemical equation? __C<sub>2</sub>H<sub>4</sub>(g) + __O<sub>2</sub>(g) → 2CO<sub>2</sub>(g) + 2H<sub>2</sub>O(g)
__C2H4(g) + __O2(g) → 2CO2(g) + 2H2O(g)Solution:1C2H4(g) + 3O2(g) → 2CO2(g) + 2H2O(g)or:C2H4(g) + 3O2(g) → 2CO2(g) + 2H2O(g)Answer: 1, 3

How many grams of sodium are needed to produce 3.90 moles of sodium oxide
____Na + ____O2 —-> ____Na2O
(both 2 are supposed to be smaller)
4Na + O2 = 2Na2On(Na) = 3.9*4 / 2n(Na) = 7.8 molem(Na) = 7.8*23 = 179.4 g
