The reactions above are examples of GENERAL REACTIONS.
- Write out each word equation and beneath each input and output classify the substance as either a metal, non-metal, acid, base, water, non-metal oxide, or metal oxide.
- For each reaction Classify the reactions above into the GENERAL REACTIONS (these can be found on your Assessment Task 11 Brief sheet.)
