types of oxides

Question 1

how are acidic oxides formed?

Answer 1

when a non-metal combines with oxygen

Question 2

acidic oxides + bases –> ?

Answer 2

salt and water

Question 3

what happens when acidic oxides are dossolved in water?

Answer 3

they produce an acidic solution with a low pH

Question 4

how are basic oxides formed?

Answer 4

when a metal and oxygen react together

Question 5

basic oxides + acids —> ?

Answer 5

salt and water

Question 6

what happens when basic oxides are dissolved in water?

Answer 6

they produce a basic solution with a high pH

Question 7

what are neutral oxides?

Answer 7

they are oxides that do not react with eiher acids or bases

Question 8

state 3 examples of neutral oxides

Answer 8

N2O, NO and CO

Question 9

how do amphoteric oxides behave?

Answer 9

they can behave as both acidic and basic depending on as to whether the other reactant is an acid or a base

Question 10

amphoteric oxide + acid –> ?
or
amphoteric oxide + base –> ?

Answer 10

in both cases, the reactions produce salt and water

Question 11

state 3 examples of amphoteric oxides

Answer 11

zinc oxide, aluminum oxide, and gallium(III) oxide
(their hydroxides also behave amphoterically)
