The law of conservation of mass states that the mass will stay constant given a chemical reaction because no atoms were created or destroyed. This being said, an example can include water evaporating in a clear bottle outside on a hot day ( the mass of the bottle will stay the same, but the liquid water evaporated into gaseous water).

The polarity of water enables it to serve as a solvent for polar substances.
A polar substance is a substance that has a positive end and a negative end. Water itself is a polar substance and this polarity enables it to dissolve polar substances.
For instance, HCl dissolves in water because it is polar. The positive end of the dipole in HCl attaches to the negative end of the dipole in water and the negative end of the dipole in HCl attaches to the positive end of the dipole in water.
This dipole - dipole interaction accounts for the dissolution of HCl in water.
Also, ion - dipole interaction accounts for the dissolution of ionic substances such as NaCl in water.

Answer:
Coombs reagent is an antiserum with antibodies that bind to the human <u>antibodies attached on the surface of the erythrocytes.</u>
Explanation:
Coombs test is a blood test used in immunology and immunohematology. It is of two types: direct and indirect.
The Coombs reagent is an antiserum, containing antibodies.
The direct Coombs test detects the antibodies present on the surface of the erythrocytes.
In this test, when the Coombs reagent is reacted with the blood to be tested, <u>the antibodies in the Coombs reagent binds to the antibodies attached on the surface of the erythrocytes in the test blood and cause agglutination.</u>
