The reaction of alkali metals with water release hydrogen.
True. Chemical changes can vary from colour change to gas production.
color change
A gas is produced when a chemical change takes place. The temperature changes and a substance disappears. A solid is formed and a color change has occurred. Another chemical change is that a new odor is produced.
Evidence that a chemical reaction has taken place usually include appearance of a precipitate, change in color, or production of a gas.
Yes. They can. The clues of a chemical reaction are production of a gas, change in temperature, color change, production of a precipitate. If you take either baking soda or baking powder, and you add them to vinegar they both form bubbles in a chemical reaction.
True. Chemical changes can vary from colour change to gas production.
The release of a gas can be a sign for a chemical reaction.
color change
No, a chemical change is when a substance and forms one or more new substances, it changes its composition. examples: changes in color production of gas formation of precipitate Boiling water is an example of physical change, it can be any phase change.
Yes
Characteristics of a chemical change can include a temperature change, a color change, the production of bubbles, the production of a precipitate, and a smell.
Fizzing is the result of a chemical change - a chemical reaction with gas releasing.
A chemical change produces a form of matter that was not there before. Evidence of a chemical change could be changes in temperature, color, smell, and the production of a gas or a precipitate.
