<h3><u>Answer;</u></h3>
Hydroelectric power
<h3><u>Explanation</u>;</h3>
- Hydroelectric power is produced when a turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.
- Hydroelectric power plants uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
Answer:
2. B. 5:3
3. C. mass and atoms only.
Explanation:
Hello there!
2. In this case, according to the given balanced chemical reaction it is possible to realize that the mole ratio of oxygen to carbon dioxide is B. 5:3 since there is a 5 on O2 and a 3 on CO2.
3. In this case, according to the law of conservation of mass it is possible to realize that matter cannot be created nor destroyed; for that reason both mass and atoms must remain unchanged as the reaction takes place; therefore the answer is C. mass and atoms only.
Best regards!
