Types Of Reactions

Question 0

Acid and metal oxide

Answer 0

Acid + metal oxide = salt + h2o

Question 1

Neutralisation

Answer 1

Acid + base = salt + H2O

Question 2

Acid and carbonate

Answer 2

Acid + carbonate = CO2+H2O+salt

Question 3

Acid and reactive metal

Answer 3

Acid + reactive metal = salt + H2 (hydrogen gas)

Question 4

Decomposition

Answer 4

1 reactant + heat = 2 or more products

Question 5

Oxidation (combustion)

Answer 5

Reactant + O2 = oxide

Question 6

Pop test

Answer 6

2H2+O2=2H2O

Question 7

Displacement

Answer 7

Metal A+Ion B = Ion A + Metal B

Question 8

Limewater rxn with CO2

Answer 8

Ca(OH)2 + CO2 = CaCO3 + H2O

Question 9

Oxidation

Answer 9

E.g) Zn(s) = Zn^(2+) + 2e-

• electrons in products

Question 10

Reduction

Answer 10

E.g) O2 + 4e- = 2O(^2-)

Question 11

Redox rxn

Answer 11

E.g) 2Mg+O2 = 2MgO

Question 12

Combustion of hydrocarbons

Answer 12

Carbon chain + O2 = CO2 + 10H2O

Question 13

Substitution

• with what?
• catalyst?

Answer 13

• alkanes and benzene
• slow rxn
• presence of UV light
• carbon chain + Br2 = (UV) carbon chain with Br + HBr

Question 14

Addition

- with what

Answer 14

Alkanes or cyclo-enes

Question 15

Addition: hydrogenation

Answer 15

Carbon chain (double bond)+H2 = break bond and add 2 H+ to carbons

Question 16

Addition: halogenation

Answer 16

Carbon chain with double bond + halogen = break x2 bond, halogens replace bond

Question 17

Addition: hydrohalogenation

Answer 17

Carbon chain + hydro-halogen (e.g HBr) = break x2 bond, H and halogen replace bond

Question 18

Addition: hydration

Answer 18

• presence of catalyst (e.g H2SO4)

Carbon chain + H2O =(catalyst) break x2 bond, H and OH replace bond

Question 19

Acid + sulfide

Answer 19

Acid + sulfide = salt + H2S(hydrogen sulfide)

Question 20

Acid + sulfite

Answer 20

Acid + sulfite = salt + SO2 (sulfur dioxide) + H2O (water)

Question 21

Acid + metal hydroxide

Answer 21

Acid + metal hydroxide = salt + H2O
