The large moons of the jovian planets
Answer:
Acids or bases can be tested by chemical indicators.
Explanation:
A chemical indicator can be described as a paper substance which changes colour when dipped in an acidic or basic solution. It can be described as a chemical indicator for hydrogen ions (H+) and hydronium ions (H3O+).
Acidic solutions normally dive red-orange colours depending on the acidicity of the substance. The basic solutions give blue-violets colours depending on the basicity of the substance.
Answer choice "C" should be correct.
Answer:
Enzymes serve as catalysts to many biological processes, and so they are not used up in reactions and they may be recovered and reused. However, in a laboratory setting, reactions involving enzymes can leave the enzyme unrecoverable. This process makes the enzyme at once less reactive but more stable.
