True 

● A catalyst acts by raising the amount of energy available for a reaction to occur. False 

● The Arrhenius theory explains why ammonia, NH3, is basic, but the Bronsted­Lowry theory  does not.

False

The mass percent of a solution that has 0.25 mol of NaOH in 100 g of solution is what?



True

False 

● A solution is a heterogeneous mixture.

False
