A reaction in which the chemical element of the reactant is replaced by another to produce a product is called a single replacement reaction.
In a reaction, a hydrogen, metal or halogen element can get replaced with other more reactive elements to yield products.
The reaction of magnesium and hydrochloric produces:
![\rm MgCl_{2}](https://tex.z-dn.net/?f=%5Crm%20MgCl_%7B2%7D)
The reaction can be explained as:
- The reaction between the
and
is a single displacement reaction in which the more reactive metal replaces the less reactive metal from the compound.
- Magnesium metal is more reactive compared to hydrogen and hence replaces
from chlorine to produce:
![\rm Mg (s) + 2 \;HCl \;(aq) \rightarrow MgCl_{2} \;(aq) + H_{2} (g)](https://tex.z-dn.net/?f=%5Crm%20Mg%20%28s%29%20%2B%202%20%5C%3BHCl%20%20%5C%3B%28aq%29%20%20%20%5Crightarrow%20%20MgCl_%7B2%7D%20%5C%3B%28aq%29%20%2B%20H_%7B2%7D%20%28g%29)
Therefore, another product formed will be magnesium chloride.

Answer:
A. Pascals
Explanation:
A unit Pascal is an SI unit used for internal pressure.
Centimeters cubed is volume.
Liters is measurement.
Kelvin is temperature.
Answer:
Binding affinity measures the strength of the interaction between a molecule to its ligand; it is expressed in terms of the equilibrium dissociation constant; and the higher value of this constant, the more weaker the binding between the molecule and the ligand is. On the other hand, small constans means that the interaction is tight. So "C" binds most tightly to the enzyme and "D" binds least tightly.
