Year 10 2013 end of year exam revision
The end of year exams are looming. It is important that you finish the year strongly and don’t switch off early. Read through the notes and watch the videos on acids and bases before attempting the questions at the end
We have studied the reactions of acids with:
- bases
- metals
- carbonates
We have used word equations to produce fully balanced chemical equations in three steps. For a little more information on this process have a look at this post about the space shuttle being blasted into orbit on the back of a huge pop test.
the basic word equations we use are:
acid + base —–> salt + water
acid + metal —–> salt + hydrogen
Acid + carbonate —–> salt + carbon dioxide + water
Use these word equations to answer the questions below.
