Mixing zinc and hydrochloric acid produces hydrogen gas bubbles.
baking soda and vinegar
All chemicals may be included in chemical reactions.
Chemical reactions can used to make soft drinks. Once bottled, the reaction stop until opened. If it is carbonated, the bubbles form when bicarbonic acid breaks down until only carbonic acid remains, then it breaks down into co2 bubbles and water.
sodium bohyroxide
All chemical reactions cause the change of color and the Change in temperature. Chemical reactions also have the characteristic of releasing gas.

The carbon dioxide bubbles from a chemical reaction.
Becasue of chemical chain reactions.
Heat helps chemical reactions to take place. Light can also cause some chemical reactions to take place.

When one chemical is mixed with another chemical, it maked chemical reactions. In this case, soda mixed with ice, would make it fizzy
Chemical reactions can be recognized by many things, but mainly include a change in color, a variation in temperature, change in shape, or the creation of bubbles.
sodium bohyroxide
cause chemical reactions cant be reversed
Chemical reactions are sources of pollution. Some examples of these reactions are: combustion, burning of fossil fuels and acid rain.
All chemical reactions cause the change of color and the Change in temperature. Chemical reactions also have the characteristic of releasing gas.
