Explanation:
Mg+O>MgO
Here the mg loses it electron and is oxidised and oxygen gains and is reduced.
Mg(2+)and O(2-)
Mg is a reducing agent it makes oxygen to be reduced while itself being oxidised and vice versa.
Answer:
Increasing the temperature of the reactants
Explanation:
This causes more vibrations to occur, hence increasing the kinetic energy of the particles. The number of particles with activation energy would increase as well because they have higher kinetic energy. Kinetic energy is also the reason why the collision between particles increases. And the frequency of effective collisions increases because of the kinetic energy as well, keep in mind the particles must also be orientated in the correct way as well.
D = m/ V
8.9 = 3 / V
V = 3 / 8.9
V = 0.3 cm³
Answer A

Although lipids hold the majority of the body's energy reserves, glycogen is the body's primary energy source.
Glucose is a polymer that makes up glycogen. Our body's primary source of energy is carbs. The remaining glucose in the body is turned into glycogen and stored in various places, but the majority of our body's energy reserves are found in fats, which are kept in the form of lipids.
Where does the energy come from in the muscles?
The chemical energy that is stored in our meals is used by muscles to produce heat and motion energy (kinetic energy). Energy is necessary for maintaining body temperature, promoting physical activity, and enabling tissue growth and repair. Foods high in protein, fat, and carbohydrates provide energy.
What Takes Place to Muscles in the Absence of Glucose?
Your body converts carbs, such as those found in bread or fruit, into glucose after consumption. Glycogen is the form of glucose that is stored in your muscles and liver and is used for energy when you are not eating or while you are exercising.
