1. If a metal reacts with an acid bubbles are seen as a colourless forms.

2a. Usually the metal to form a solution.
2b. Other signs of a chemical change may include a change and a temperature .

3. The gas gives a squeaky with a lit splint, and so is .

4. The part of the name of the salt formed is the metal added to the acid.

5. The part of the name depends on the acid used. Hydrochloric acid makes a salt, acid makes a nitrate salt, and sulphuric acid makes a salt.

6. The metals are NOT equally and form an 'activity series'. For example, reacts than iron, and one of the least reactive is .

7. Calcium, quite a reactive metal, is slow reacting in acid because calcium sulphate isn't very . When it forms it coats the calcium metal the reaction down.

8. Complete the word equations:
(a) + nitric acid ==> magnesium + hydrogen
(b) + sulphuric acid ==> iron sulphate +
(c) zinc + acid ==> chloride + hydrogen
