Write the balanced chemical equation for the following along with the states. (2)
Silvery shinning aluminium metal reacts with blue coloured copper (II)
chloride solution and forms colourless solution of aluminium chloride along
with reddish brown copper metal.
Give one characteristic of the above chemical reaction.
Answers
Answer:
answer
Explanation:
1.(a) Calcium hydroxide + Carbon dioxide → Calcium carbonate + Water
(b) Zinc + Silver nitrate → Zinc nitrate + Silver
(c) Aluminium + Copper chloride → Aluminium chloride + Copper
(d) Barium chloride + Potassium sulphate → Barium sulphate + Potassium chloride.
2. Magnesium is an very reactive metal. ... 2. Write the balanced equation for the following chemical reactions. ... Therefore the colour of the copper sulphate solution changes.
3. When a piece of iron metal is placed in copper sulphate solution, then magnesium sulphate solution and copper metal are formed. This is a type of displacement reaction.
CuSO4 + Fe → FeSO4 + Cu
(b) Na2SO4 + BaCl2 → BaSO4 + 2NaCl.
4. The characteristics of a chemical reaction are : Evolution of gas. Formation of a precipitate. Change in color.
