Complete the given chemical reaction: CuSO 4 aq + Fe s → _____ + _____ . Name the type of reaction.

The given equation represents the reaction of iron with copper sulphate solution. The chemical equation is as follows: CuSO 4 aq + Fe s → FeSO 4 ( aq ) + Cu ( s ) It is a displacement reaction. Iron is being more reactive in the activity series of metals displaces copper ions from an aqueous solution of copper sulphate. In this reaction, metallic iron is converted into ferrous ion Fe 2 + and cupric ion Cu 2 + is converted into metallic copper. A brown coating of copper is formed on the surface of iron and the colour of the copper sulphate solution changes from blue to light green.

What are covalent compounds? Write any three features and give two examples.

A covalent compound is a molecule formed by covalent bonds. A covalent bond is a chemical bond that is formed by the sharing of electron pairs between atoms. The covalent compound is a result of two non-metals reacting with each other such that they are electrically neutral. Any three features of the covalent compound are: 1. Covalent compounds do not conduct electricity. 2. The melting and the boiling points of covalent compounds are generally low. 3. Covalent compounds are insoluble in water but soluble in organic solvents. Two examples of covalent compounds are: oxygen molecules and hydrogen chloride. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
