d. The following hormones is not secreted by human placenta LH.

Ksp = (3 S)2 (2 S)3 = 72 S5

(c) The composition of kidney stone is Calcium oxalate                – 80% Uric acid                           – 5% Amino acid cystine             – 2 % Magnesium and                 – 13% ammonium phosphate

(A)  correct answer is 7g Explanation: When 5g of calcium is burnt in 2g of oxygen ,we get 7g of calcium oxide  From this we understand that, calcium  and oxygen combine in...

(a) Ca(OH)2+CO2  → CaCO3+H2O (b) Zn+2AgNO3 →  Zn(NO3)2+2Ag (c) 2Al+3CuCl2 → 2AlCl3+3Cu (d) BaCl2+ K2SO4 → BaSO4+2KCl

(b) Acid rain reacts with calcium to form calcium bicarbonate, which can be easily washed away.

(i) It is a metal. Since it has two electrons in its outermost shell/two valence electrons, which it can lose easily. (ii) K(19) is placed before Ca(20) in the same period/fourth period. Since...
