Hydrogen
When a metal reacts with an acid, this gas is commonly produced.
Hydrogen Gas
This gas is produced when a metal carbonate reacts with an acid.
Carbon Dioxide
What is the general formular for a combination (synthesis) reaction?
A + B --> AB
These are the basic building blocks of all matter.
Atoms
