In graphite, each carbon atom is bonded to other carbon atoms in the same plane.

One mole of carbon atoms weighs 12g (Given)  i.e., mass of 1 mole of carbon atoms = 12g  Then, mass of 6.022× 1023 number of carbon atoms = 12g  Therefore, mass of 1...

1 mole of C = 12 g  Number of atoms in1 mole of C = 6.022 × 1023 atoms  Mass of 6.022 × 1023 atoms of C = 12 g  Mass of 1...

(a) Mass of sodium atoms carried by Krish = (5 × 23) g = 115 g While mass of carbon atom carried by Raunak = (5 ×12) g = 60g...

8 corner × 1/8 atom per unit cell = 1 atom  There are four body diagonals in a cubic unit cell and each has two body centre atoms.  So, 4 × 2...

(b) Primary and secondary markets complement each other. Primary market deals with the issue of new securities. That is, through the primary market a company raises capital directly from the borrowers....

(d) : Graphite has a twodimensional sheet like structure and each carbon atom makes a use of sp2 hybridisation.  The above layer structure of graphite is less compact than that of...

15 H attached to five 10 carbon. 4H attached to ten 20 carbons 1H attached to one 30 carbon.

We are given (i) C(graphite) + O2(g) → CO2(g); ΔH=-393.4KJ (a) From the above equation, we know that 393.4 KJ of heat is produced by 12 g of graphite. 196.7 kj of heat...

(c) If assertion is true, but reason is false.
