Homework Help: Chemistry

Posted by Annonomous on Monday, April 20, 2009 at 10:26pm.

Need help on how to balance equations. Here are a few of the problems.

First let me supply the w/s directions:

Predict the products of the reactions below. Then, write the balanced equation and clasify the reactions.

Here are examples of a few of the different kinds of equations I have to balance:

1. sodium + hydrogen

2. sulfuric acid + sodium hydroxide

3. hydrogen peroxide

4. zinc + hydrochloric acid

I really don't understand how any of this is done, so, an explaination of where any numbers or such comes from would be ideal.
