Answer:
Salt is a mineral/substance that is made up of sodium chloride. It is typically used as a food ingredient and a nutrient. There are different types of salt such as kosher salt, table salt, sea salt, smoked salt, etc.
Answer:
molecular diagram 3 or 2 is correct answer I hope it helps you
a) Mg is oxidized and O2 is reduced
b) Zn is oxidized while Pb(NO3)2 is reduced.
<h3>Oxidation and reduction</h3>
Oxidation is defined as:
- loss of electrons
- removal of hydrogen
- addition of oxygen
- increase in oxidation number
- removal of electropositive elements
Reduction is defined as:
- gains of electrons
- addition of hydrogen
- removal of oxygen
- decrease in oxidation number
- addition of electropositive elements
Looking at the first reaction, the Mg atom gains oxygen to become MgO. This means that Mg is oxidized. The oxidizing agent is O2. At the same time, O2 is being reduced and the reducing agent is Mg.
For the second reaction, the oxidation number of Pb is reduced from +2 to 0. Thus, Pb has been reduced by Zn while Zn itself has been oxidized. The reducing agent here is Zn while the oxidizing agent is Pb(NO3)2.

<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.
