Explanation:
Basically, the hydroxonium ions, H3O+ are responsible for the acidity of a solution and the hydroxide ions, OH- are responsible for the basicity of a solution.
In an acid solution;
The concentration of the hydroxonium ions is greater than that of the hydroxide ions.
In a basic solution;
The concentration of the hydroxide ions is greater than that of the hydroxonium ions.
The answer is D. just like the other guy said...
To answer this expression we should follow the mathematical rule. The mathematical rule that we will follow is called BODMAS short for brackets, powers, divide, multiply, add, subtract. So, we will first solve the one in the brackets which is <span>(72.61 - 68.59) is equal to 4.02 then we will multiply this to 18.76 and the answer is 75.4152.</span>
Intermolecular forces are forces of interaction that are operative between two different molecules. They are of follow types
1) Dipole- dipole interaction
2) Hydrogen bonds
3) vander Waal's forces
Depending upon the polarity and constitution molecule above forces are operable.
for instance, in case of ammonia, Hydrogen bonds exist because hydrogen atom is attached to electronegative element i.e. N
HCl and CO are polar molecules, so dipole-dipole interaction is operative in these molecules.
Finally in case of CO2, vander Waal's forces of interaction is operable because it is a non-polar molecule.
