Answer 1

Limiting Reactant

Question 2

what is left over after the reaction stops because the limiting reactant got all used up

Answer 2

Excess Reactant

Question 3

Percent Yield Formula

Answer 3

Actual Yield/Theoretical Yield

Question 4

substances that taste sour and release hydrogen ions (H) when dissolved in water

Answer 4

Acids

Question 5

Are highly corrosive, Can damage metals and potentially cause burns on the skin (Example is hydrochloric acid)

Answer 5

Concentrated acids

Question 6

Bases that dissolve in water, Feel slippery, taste bitter, and they release hydroxide ions (OH) in water

Answer 6

Alkalis

Question 7

a substance that neutralises acids

Answer 7

Base

Question 8

an acid generates H+ ions in a solution whereas a base produces an OH– ion in its solution

Answer 8

Arrhenius theory

are formed when acids and alkalis mix and neutralize each other (neutralisation reaction)

Answer 9

salt and water

Question 9

acids as electron-pair acceptors and bases as electron-pair donors
