Stomach acid is a dilute solution of hydrochloric acid (hcl). in this case the word dilute means
a. dissociation is incomplete.
b. the ph of stomach acid is relatively high.
c. there are relatively few h+ formed.
d. there are a relatively small number of moles of hcl present.

d.there are a relatively small number of moles of HCl present.

Explanation:

Generally, a solution is formed when a solute is dissolved in solvent. A dilute solution have relatively high amount of solvent compare to the solute. The solute present in the solvent is small in a dilute solution.

A dilute acid is one which the concentration of water in the solution is higher than the concentration of the acid itself.  The concentration of the acid in the aqueous solution is usually lower for a dilute solution. This means a dilute solution of the hydrochloric acid contain a low concentration of the acid in gram per moles .

The option A is incorrect because it shows the acid is weak .A weak acid is one which the ions dissociate partially in solution.

The option B gives information on the H+ formed in the aqueous solution. The higher the H+ contents ,the lower the pH value. The hydrogen ion contents gives information on the pH scale. The question didn't say anything about the H+ contents. Having relatively high pH scale only proves the H+ contents is low.

The best description of the word dilute is when the HCl contains relatively small amount of the acid in the solution.

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
