We are given the chemical reaction and the amount of reactant used for the process. We use these data together to obtain what is asked. We do as as follows:
0.882 mol H2O2 ( 1 mol O2 / 2 mol H2O2 ) = 0.441 mol O2 produced
Hope this answers the question.
Carbonates
OPTION A is the correct answer
True...............................
Answer:
1. Chemical reactions
2.Substances
3. Properties
4. Precipitate
5. Light
6. Temperature
7. Color
8. Gas
Explanation:
Chemical reactions are known to produce new substances which have new properties. During the chemical reactions, evidences that are seen are formation of precipitate or light gel, production of gas and change in temperature and color.
Chemical reactions occur when chemical substances come together to react because those substances are compatible with each other.
