How much energy is released when 57.0 g of ethylene reacts? Be sure your answer has the correct number of significant figures.

Question

Consider the gas-phase reaction of ethylene (C2H4) with hydrogen (H2) to form ethane (C2H6), which occurs in the presence of a palladium catalyst.

Part: 0 / 7

Part 1 of 7

Write a balanced equation for this equilibrium. Do not include the palladium catalyst. Include all physical states of matter.

C2H4(g)+ H2(g) = C2H6 (g)

Answer 1

C2H4(g) + H2(g) → C2H6(g)
