An arrhenius acid has
A only hydroxide ions solution
b only hydrogen ions solution
c hydrogen ions as the only positive ions in solution
d hydrogen ions as the only negative ions in solution

c.

Explanation:

An Arrhenius acid  increases the number of H+ ions in solution. They are the only positive ions in the solution.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry
