how to solve the chemical equations?
Answers
Answer:
This is usually called “balancing” a chemical equation: making sure that equal numbers of each element appear on both sides. When I was in junior high school, we were told to do this by a certain method. There were rules about balancing the hydrogens first, and so on, then doing it by trial and error. I got frustrated with spending hours trying to balance equations by this method — balancing one element always caused others once to be out of balance. So on my own, I came up with another, systematic method using algebra.
As an example, take the unbalanced equation:
Fe 2 O 3 + C → Fe + CO 2
Here there are 2 Fe (iron) on the left and 1 on the right; 3 O (oxygen) on the left and 2 on the right; and 1 C (carbon) on both sides
