One element takes the place of another in a compound.
When magnesium is added to hydrochloric acid, a single replacement reaction occurs. The magnesium displaces the hydrogen in the acid to form magnesium chloride and hydrogen gas. The reaction is as follows: Mg + 2HCl → MgCl2 + H2.
After a biochemical reaction, an enzyme typically remains unchanged and can be reused in other reactions.
In an endothermic reaction, energy is absorbed from the surroundings, causing the surroundings to feel cooler. This is in contrast to an exothermic reaction, where energy is released into the surroundings, causing them to feel warmer.
During an exothermic reaction, heat is released to the surroundings, resulting in an increase in temperature. In contrast, an endothermic reaction absorbs heat from the surroundings, causing a decrease in temperature.
When a reaction is at equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time, creating a balanced state where no further changes occur.

It is unchanged by the reaction.
a reaction happens
A synthesis reaction.
catalyzed reaction
Rate of forward reaction=rate of backward reaction
This is an oxydation reaction.

There is a reaction.
it is a combustion reaction or oxidation snce it happens with oxygen.
something happens
It is reduced
