1a. Acids react with metal  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc to form a salt and  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc. There is no bubbling observed because no  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc is formed. This reaction can be used to prepare  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc.
1b. The black solid  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc oxide is added to dilute sulfuric acid in order to prepare copper  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc.
2. The  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc is heated to speed up the  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc process. More black powder is  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc until no more dissolves.
3. The excess copper  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc is  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc off to leave a  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc blue solution of the salt.
4. The filtered liquid is heated to  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc the water and leave the salt  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc. If the solution is left for a long time it  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc crystallises to form  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc crystals.
5. Complete the word equations:
(a) magnesium oxide +  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc acid ==>  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc nitrate + water
(b) iron oxide + hydrochloric acid ==> iron  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc +  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc
(c)  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc oxide +  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc  acidaddedbiggerchlorideclearcoppercrystalsdissolvingevaporatefilteredgasmagnesiummixturenitricoxideoxidessaltsslowlysulfatesulfuricwaterzinc ==> zinc sulfate + water
