5

When some metallic hydroxides or oxyacids are heated, they decompose to form

metallic (or nonmetallic) oxide and water

6

Combustion of a metal or non metal produces the ___

common oxide of the element

7

Complete combustion of hydrocarbons produces

carbon dioxide and water

8

Incomplete combustion of hydrocarbons produces

carbon monoxide and energy

9

Ammonium salts react with metallic hydroxides and oxides in an acid/base reaction to produce

salt + ammonia + water

10

An acid and a carbonate compound yield a ___ and ____, which decomposes into ___ and ___

salt and bicarbonate, which decomposes to carbon dioxide and water

11

collision-reaction theory

a theory stating that chemical reactions involve collisions
and rearrangements of atoms or groups of atoms, and that the outcome of collisions depends on the ENERGY and ORIENTATION of the collisions

12

binary acids are composed of ___

hydrogen and another non-metal (eg hydrochloric acid HCl)

13

oxyacids are composed of ___

hydrogen and an oxyacid radical/polyatomic ion (eg sulphuric acid H2SO4)

14

oxyacid radicals

polyatomic ions with different numbers of oxygen atoms (eg SO4, SO3, SO2)

15

What are acid salts?

Metal + oxyacid ion with -2 or -3 charge (e.g. NaH2PO2 sodium dihydrogen hypophosphite)

16

Oxyacid radicals : -IC acid (base formula)

Anion: -ATE
Acid: -IC

17

Oxyacid radicals: 1 more than base formula

Anion: PER-/-ATE
Acid: PER-/-IC

18

Oxyacid radicals: 1 less than base formula

Anion: -ITE
Acid: -OUS

19

Oxyacid radicals: 2 less than base formula

Anion: HYPO-/-ITE
Acid: HYPO-/-OUS

20

Nomenclature for compounds with no oxygen

Anion: -IDE
Acid: HYDRO-/-IC

21

endothermic vs exothermic reaction

endothermic: heat energy is transferred from surroundings into system
exothermic: heat energy is released from the system into surroundings

22

When H2O splits into ions, it splits into...

H+ and OH-

23

To know the outcome of a single displacement reaction, you have to think of the ____

activity series
