Answer 7

Salt + hydrogen

Question 8

Acid + Base ->

Answer 8

Salt + Water

Question 9

Acid + Carbonate ->

Answer 9

Salt + Water + carbon dioxide

Question 10

(A)Nitrate + (B) chloride ->

Answer 10

(B)Nitrate + (A)Chloride

Question 11

(A)Oxide + (B)

Answer 11

(B)Oxide + (A) where B is higher up in the reactivity series than A

Question 12

A + Oxygen ->

Answer 12

A Oxide, where A is a metal that corrodes or rusts

Question 13

Group 1 Metal + Water ->

Answer 13

Metal Hydroxide + Hydrogen

Question 14

Why does sodium have a +1 charge

Answer 14

During a reaction, it looses it’s single electron in the outer shell to the other atom- the sodium now has 1 more proton than electron, giving it a +1 charge

Question 15

State why reacting Magnesium Oxide and copper will not work (displacement reaction)

Answer 15

Magnesium is higher up in the reactivity series, meaning copper can’t “steal” the oxygen from it

Question 16

State the charge on group 2 metals

Answer 16

2+
