metal hydroxide + hydrogen gas
4 of 29
2Na(s) + 2H2O(l)
2NaOH(aq) + H2(g)
5 of 29
Hydrogen chloride dissolved in acid
Makes hydrochloric acid (forms H+ ions)
6 of 29
Hydrogen chloride dissolved in methylbenzene
Doesn't produce acid as it doesn't dissociate
7 of 29
Halogen displacement
More reactive halogen displaces the less reactive halogen
8 of 29
Displacement: Cl2(aq) + 2NaBr(aq)
2NaCl(aq) + Br2(aq)
9 of 29
Copper + oxygen --> copper oxide
2Cu + O2 --> 2CuO (volume of air decreases 20%)
10 of 29
Iron + oxygen + water --> hydrated iron (III) oxide
4Fe + O2 + H2O --> 2FeO3.nH2o (volume of air decreases by 20%)
11 of 29
Phosphorous + oxygen --> phosphorus oxide
4P + O2 --> P4O10 (water level in bell jar rises by 20%)
12 of 29
Hydrogen peroxide --(manganese 4 oxide)--> oxygen + water
2H2O --(MnO2)--> O2 + 2H2O (oxygen collected by downwards displacement method)
13 of 29
Magnesium + oxygen --> magnesium oxide
2Mg(s) + O2(g) --> 2MgO(s) (magnesium produces bright white flame, leaves white ash which is slightly alkali when dissolved)
14 of 29
Carbon + oxygen --> carbon dioxide
C(s) + O2(g) --> CO2(g) (carbon only burns in air if strongly heated with yellow-orange flame, CO2 is slightly acidic)
15 of 29
Sulfur + oxygen --> sulfur dioxide
S(s) + O2(g) --> SO2(g) (burns with pale blue flame, sulfur dioxide acidic)
16 of 29
Hydrochloric acid + calcium carbonate --> calcium chloride + water + carbon dioxide
2HCl(aq) + CaCO3(s) --> CaCl2(aq) + H2O(l) + CO2(g)
17 of 29
Copper (II) carbonate --> copper oxide + carbon dioxide
CuCo3(g) --> CuO(s) + CO2(g) (produced by thermal decomposition)
18 of 29
Hydrogen combustion
2H2O + O2 --> H2O (hydrogen burnt in air produces water)
19 of 29
Alkanes formula
CnH2n+2
20 of 29
Alkenes formula
CnH2n
21 of 29
Bromine and methane in a UV light form bromomethane
CH4 + Br2 --> CH3Br + HBr (bromine takes the place of hydrogen)
22 of 29
Addition reaction of alkenes with bromine
Alkene makes double bond into single bond to bond to 2 bromines (C2H4 + Br2 --> C2H4Br2)
23 of 29
