Balance the following reaction. Choose "blank" if no coefficient is needed. C 2 H 5 + O 2 → CO 2 + H 2 O

4 C2H5 + 13 O2 -> 8 CO2 + 10 H2O

Explanation:

What I do is I make a chart of how many elements the product side and reactant sides have:

Reactants-

2 C

5 H

2 O

Products-

1 C

3 O

2 H

It's easier to see how many coefficients are needed for the reaction to be balanced then. Hope this helped.

passing a magnet thought the

mixture , because iron gets attracted to magnet .
