Dalton was the first scientist to create an atomic theory but he wasn't given any credit. J.J Thompson was credited for his theory (apple pudding)
Answer:
The charge on the metal is +2
Explanation:
Taking a good look at the compound zinc nitride, we will notice that it is made up of zinc and nitrogen.
Zinc has a common common oxidation state of +2 while nitrogen has a common oxidation state of -3. When the two atoms combine, the individual charges on them will be +2 for zinc and -3 for nitrogen according to their common oxidation states.
Hence the answer.
<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.
