Question

1. What are the products of most combustion reactions?

2. Why are metal alloys an example of a physical change and not a chemical change?

Please Help!!!! :(

Answer 1

1.Products of most combustion reactions are:
Carbon dioxide and water
2.Alloys are made by melting and combining metals together.
Chemical changes involve electrons,in this process no electron is used/shared or given.
Thus,its not a chemical change.
