1. Write down the overall chemical reaction of a process in which glucose in broken down to two molecules of pyruvic acid?
Overall reaction of glycolysis:
Glucose + 2 ATP + 2iP + 4 ADP + 2 NAD+ → 2 Pyruvate + 2 ADP + 4 ATP + 2 NADH + 2 Ha+ + 2 H2O
2. Write condensed electronic configurations of the following elements.
13Al, 49In, 14Si, 50Sn, 15P, 33As
Condensed electronic configurations of
i. 13Al: [Ne]3s2 3p1
ii. 49In: [Kr]4d105s25p1
iii. 14Si: [Ne]3s23p2
iv. 50Sn: [Kr]4d105s25p2
v. 15P: [Ne]3s23p3
vi. 33As: [Ar]3d104s24p3
3. Prove the following
Answer:
Taking (n + 1) A= x and (n + 2) A = y, we get
L.H.S. = sin x sin y + cos x cos y
= cos x cos y + sin x sin y
=cos(x — y)
= cos [(n + 1)A — (n + 2)A]
= cos (nA + A — nA — 2A)
=cos(— A)
= cos A
= R.H.S.
