Please complete the following word equations: 1. Iron Sulphate + Zinc ⇒ 2. Copper Sulphate + Iron ⇒ 3. Aluminium + Hydrochloric Acid ⇒ 4. Magnesium + Sulphuric Acid⇒
Answers
Explanation:
) Dilute sulphuric acid reacts with zinc granules to produce zinc sulphate and hydrogen gas
H2SO4(aq)+Zn(s)→ZnSO4(aq)+H2(g)
(b) Dilute hydrochloric acid reacts with magnesium ribbon to produce magnesium chloride and hydrogen gas.
2HCl(aq)+Mg(s)→MgCl2(aq)+H2(g)
(c) Dilute sulphuric acid reacts with aluminium powder to produce aluminium sulphate and hydrogen gas.
3H2SO4(aq)+2Al(s)→Al2(SO4)3(aq)+3H2(g)
(d) Dilute hydrochloric acid reacts with iron filings to produce ferric chloride and hydrogen gas.
6HCl(aq)+Fe(s)→2FeCl3(aq)+3H2(g)
Answer:
1st : when the iron sulphate added to zinc the iron sulphate can change the colour because zinc is a more reactive than iron. therefore it displays iron from it iron sulphate and a grey perticipate of iron and colourless zinc is formed .
2nd : iron displays the copper ions from an aqueous solution of copper sulphate . it is a single displacement reaction of one metal of another metal . iron is placed copper in the activity series . element placed above in the series are more reactive than those placed above them.
3rd ammunium reacts with hydrochloride acid to produce alluminium chloride and hydrogen gas .
4th magnesia metal dissolve rapidly in dillute sulpharic acid to form solutions containing the aquated mg( ll )ion together with hydrogen gas , H2 .
