Copper(II) chloride reacts with sodium phosphate to form sodium chloride and solid copper(II) phosphate in a precipitation reaction.
Type of Reaction: Double replacement (with formation of insoluble solid)
NaOH(aq) ⟶ NaCl(aq) + H2O(l)
Hydrochloric acid reacts with sodium hydroxide to form sodium chloride and water in an acid-base reaction.
Type of Reaction: Double replacement (acid-base)
3O2(g) ⟶ 2CO2(g) + 3H2O(g)
Ethanol (grain alcohol) combusts in the presence of oxygen gas to form carbon dioxide and water vapor.
Type of Reaction: Combustion
I've used this lab for a few years but this year I
only have one block in which to do the lab so some
preparation was necessary. I gave students for homework
the task of writing out the relevant chemical equations
but this worksheet (with the answers on the back if
printed two-sided) will help speed things along.
