Homework Help: Science

Posted by Sara on Tuesday, March 23, 2010 at 10:30pm.

We did a experiment in class to recognize chemical change.

I don't really get this question: Identify the combinations of chemicals in which chemical changes occurred.

If the chemical changes occured in all of the combinations, then what would be a good answer?

I get the second part which is: What evidence showed that chemical changes had occured. ~ New colour arose.

Since I don't know what chemicals were combined, I can't give an adequate answer.

A color change can be one indicator. Did anything else happen?

I hope this helps.
