2.1.2 Compounds, formulae and equations
Cards in this deck (5)
- 12.1.2 (a) (i) What is the ionic charge of each group on the periodic table?
- 22.1.2 (a) (ii) Recall the names and formulae for the ions you need to rememberNO3– = Nitrate
CO32– = Carbonate
SO42– = Sulphate
OH– = Hydroxide
NH4+ = Ammonium
Zn2+ = Zinc (II) ion
Ag+ = Silver Cation - 32.1.2 (b) What does each state symbol mean?(s) = Solid
(l) = Liquid
(g) = Gas
(aq) = Aqueous [dissolved in water] - 42.1.2 (b) What is the key to balancing equations?- Number of each atom must be the same on both sides
- The products are just a rearrangement of the reactants [nothing added or removed]. - 52.1.2 (b) What is the key to constructing ionic equations?Write down charges of each element and remove any elements that keep the same charge as a reactant and as a product until all that remains are the charges that change.
