In which of the following, the oxidation number of oxygen has been arranged in increasing order?
BaO2 < KO2 < O3 < OF2
OF2 < KO2 < BaO2 <O3
BaO2 < O3 < OF2 < KO2
KO2 < OF2 < O3 < BaO2
Consider the following solutions,
A = 0.1 M glucose,
B = 0.05 M NaCl,
C = 0.05 M BaCl2
D = 0.1 M AlCl3
Which of the following pairs is isotonic?
A and B
A and D
A and C
B and C
A.
A and B
Isotonic solutions have a same molar concentration of solute particles in solution. Molar concentration of particles in solution are,
(a) = 0.1 M in glucose
(b) = 2 x 0.05 M in NaCl2
(c) = 3 x 0.05 M in BaCl2
(d) = 4 x 0.1 M in AlCl3
Hence, 0.1 M glucose and 0.05 and
when CO2 is bubbled through a solution of barium peroxide in water then
Carbonic acid is formed
O2 is released
H2O2
No reaction occurs
