Question

Match the following. 'A' (a) Fullerene (b) Graphite (c) Diamond (d) Washing Soda 'B' 1. Na2CO3 2. Cutting metals 3. hexagonal arrangement of atoms 4. C60

Answer 1

Answer :

(a) Fullerenes - (4) $C_{60$

(b) Graphite - (3) Hexagonal arrangements of atom

(c) Diamond - (2) Cutting metals

(d) Washing Soda - (1) $Na_2CO_3$

Step-by-step explanation :

(a) The molecular formula of fullerenes is $C_{60}$

(b) Graphite has hexagonal arrangements of atom.

(c) Diamond is used for cutting metals.

(d) The molecular formula of washing soda is $Na_2CO_3$

Answer 2

     Fullerene – It is a form of a carbon is a fullerene,  in which carbon atoms are arranged in a sphere.

Each sphere has 60 carbon atoms and each carbon atom is linked by a single covalent .The bonds which are present in carbons are relatively weak.

    Graphite - It is a crystalline carbon form in which each carbon atom is connected to three additional carbon atoms. In each single layer of carbon atoms have strong bonds  but only weak bonds are present in between layers .

    Diamond - is a carbon form in which each carbon atom is linked to four additional carbon atoms. This forms a strong, rigid and three-dimensional structure.

    Sodium carbonate is called as washing soda. Molecular formula is Na2CO3.
