Oxidation and Reduction: Redox Reactions
Oxidation and reduction reactions occur simultaneously. When oxidation occurs in one substance, reduction takes place in the other substance. Such reactions are called redox reactions. In the name ‘redox’, the term ‘red’ stands for reduction and ‘ox’ stands for oxidation.
CuO + H2 → Cu + H2O
Fe3O4 + 4H2 → 3Fe + 4H2O
In both, the above reactions, oxidation and reduction occur simultaneously. One of the reactants acts as an oxidising agent and gets reduced, while the other acts as a reducing agent and gets oxidised.

Equilibrium price refers to the price at which market demand is equal to market supply, which means where there is no excess demand or excess supply.
When price will rise above the equilibrium price, demand will be less than supply i.e. there will be excess supply in the market.
Excess supply of a good creates competition among the sellers of the good, because the sellers will not be able to sell all they want to sell at the existing price. This leads to fall in price of the good.
With fall in price of goods there will be rise in demand. The change will continue till demand for the good equals to its supply and the market is in equilibrium again. Thus, equilibrium price will be restored through the free play of market forces.

The amount of blood pumped by heart per minute is called cardiac output. It is calculated by multiplying stroke volume (volume of blood pumped by each ventricle per minute) with heart rate (number of beats per minute). The heart of normal person beats 72 times per minute and pumps out about 70 mL of blood per beat. Therefore, cardiac output averages 5000 mL or 5 litres.
