When two clear solutions are mixed together in equal amounts a solid bright yellow substance settles out of the solution which best describes what has occurred? Which indicates a chemical reaction is occurring? When two clear solutions are mixed together in equal amounts, a solid bright yellow ...
When a reaction occurs between ammonia and water, what happens? When the concentration of the reactants is higher than the equilibrium concentration, what happens? What happens when hydrogen ions is added to acetic acid and acetate compared to when hydroxide ions are added ?
A catalyst affects the at which a chemical reaction occurs, but it is not itself changed during the reaction. When water changes from a liquid to a gas, this is called ___. When the concentration of the reactants is higher than the equilibri...
