Answer:
C-BY LOSING ONE OR MORE ELECTRONS
I'll do A for you. They are all double displacement reactions. So recall: AB+CD--> CB+AD . Also, knowing the charges will help and make this so easy.
Radio waves have the lowest energy, but the longest wavelength. So radio waves is the answer. Good luck on the rest and message me for more help.
Explanation:
The reaction rate decreases with a decrease in temperature. Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction. Differences in the inherent structures of reactants can lead to differences in reaction rates.
Answer:
It is incorrect because sodium phosphate is a compound that has a single composition.
Explanation:
Sodium phosphate is a compound and not a mixture. It is made up of sodium and phosphate ions and they exists as just a single compound and not different entities.
The parts of a mixture exists separately and they retain their identities.
- In the compound a sodium phosphate we have 3 atoms, Na, P and Oxygen joined together in a definite grouping.
- The properties of the compound are different from the individual elements that makes them up.
