1a. Acids react with metal addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc to form a salt and addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc. There is no bubbling observed because no addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc is formed. This reaction can be used to prepare addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc.

1b. The black solid addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc oxide is added to dilute sulphuric acid in order to prepare copper addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc.

2. The addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc is heated to speed up the addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc process. More black powder is addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc until no more dissolves.

3. The excess copper addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc is addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc off to leave a addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc blue solution of the salt.

4. The filtered liquid is heated to addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc the water and leave the salt addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc. If the solution is left for a long time it addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc crystallises to form addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc crystals.

5. Complete the word equations:

(a) magnesium oxide + addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc acid ==> addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc nitrate + water

(b) iron oxide + hydrochloric acid ==> iron addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc + addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc

(c) addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc oxide + addedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulphatesulphuricwaterzinc acid ==> zinc sulphate + water
