How can the speed of solvent molecules be slowed down?

Explanation:

When we decrease the temperature, then there will be less collision between the particles. As a result, there will be decrease in the kinetic energy of molecules. Therefore, molecules will start to settle at the bottom.

Hence, there will be decrease in the speed of molecules.

Thus, we can conclude that on decreasing the temperature the speed of solvent molecules be slowed down.

By decreasing the temperature of the solvent

Explanation:

The speed of the solvent is dependent on the kinetic energies of the solvent molecules. The higher kinetic energies means that there is a diffusion of the molecules in solution. Higher temperatures mean higher kinetic energies of the molecules. Thus, by definition, temperature is the measure if the average kinetic energies of molecules.

Lowering the temperatures lowers the average kinetic energies if the molecules. Hence less diffusion.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
