Equations Flashcards
1
Q
The reaction between an acid and a base
A
Hydrochloric acid + sodium hydroxide = sodium chloride + water
HCL + NaOh = NACL + h20
2
Q
Metal and an acid
A
2hcl + 2Na = 2NACL + h2
3
Q
A carbonate and an acid
A
Hydrochloric acid + calcium carbonate = calcium chloride + carbon dioxide + water
2HCl + CaCl2 = CaCl2 + CO2 + H2O
4
Q
Preperation of oxygen
A
Hydrogen peroxide + manganese dioxide = oxygen and water
2h2o2 – MNo2— = O2 + 2h2O
5
Q
Preperation of carbon dioxide
A
Calcium carbonate + hydrochloric acid = calcium chloride + water + carbon dioxide
6
Q
Test for carbon dioxide
A
Calcium hydroxide + carbon dioxide = calcium carbonate + water
Ca(OH)2 + CO2 = CaCO3 + H2O
7
Q
Splitting water
A
2H2O = 2H2 + 02
