Using the balanced equation

2c2h6 +702 --> 4co2 +6h20
if 43 g c2h6 react with 105 g o2, what is the excess reactant?

-c2h6
-co2
-h20
-o2

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

b.final

the answer is a and have a great day
