Solution:
QUESTION: 14
Which one of the following represents the correct order of electronegativity
Solution: The electronegativity values for the representative elements increase along a period from left to right and decrease down a group. This is because, as we move along the period from left to right nuclear charge increases and atomic radius decreases whereas when we move down the group, the atomic radius as well as screening effect increases. Thus, the order of electronegativity of N, O and P is
O > N > P

Solution:
QUESTION: 36
WHich of the following polymer is an example of fibre?
Solution:
QUESTION: 37
The electronegativity follows the order
Solution: The electronegativity values for the elements decrease down a group. This is because as we move down the group atomic radius as well as screening effect increases. Thus, the force of attraction with which the nucleus pulls the valence electrons towards itself decreases and consequently the electronegativity values also decrease. The electronegativity values follows the order:
F > Cl > Br > I

Solution:
QUESTION: 43

If 0.5 mol of BaCl₂ is mixed with 0.2 mol of Na₃PO₄, the maximum number of mole of Ba₃(PO₄)₂ that can be formed is
Solution:

2 mol of Na3PO4 reacts with 3 mol of BaCl2 to form 1 mol Ba3(PO4)2
∴ 0.2 mol of Na3PO4 reacts with 0.3 mol of BaCl2 to form 0.1 mol Ba3(PO4)2.
Thus,Na3PO4 is limiting reagent here.
