what is energy release (light, heat) odor, color change, and sound.
When balancing an equation, these numbers can not be changed.
What is a subscript?
Nitrogen gas and hydrogen gas are mixed together to form ammonia (NH3). Classify.
What is synthesis?
N2 + 3 H2 → 2 NH3
Balance the following equation:
