Answer:
identical conditions, separate samples of O2 and an unknown gas were allowed to effuse through identical membranes simultaneously. After a certain amount of time, it was found that 6.23 mL of O2 had passed through the membrane, but only 3.85 mL of of the unknown gas had passed through. What is the molar mass of the unknown gas

Answer:
24.1kJ
Explanation:
Heat capacity of water = 4200
Latent Heat of ice = 333550
Heat of Fusion = m × l = 333550 × (32/1000)kg = 10,672 = 10.672kJ
H = (m × c × change in temperature)
H = (32/1000)kg × 4200 × (85 -- 15)
H = (32/1000) × 4200 × 100
H = 13,440J = 13.44kJ
So amount of heat = 13.44kJ + 10.672kJ = 24.112kJ ~ 24.1kJ
mass spectrum of tertiary butyl chloride having overall mass as 92 m /Z for Cl35 and 94 m /Z for Cl37. The major peak at 57 m /Z for the removal of chlorine - 37 radical whereas other peak appear at 77 m /Z after removal of a methyl radical.
Ir of tertiary butyl chloride appear majorly at 3000 Cm^-1 whereas other small peaks appear between 1400- 1550 Cm-1
Answer:
an Additional shell
Explanation:
Potassium has an additional energy level when compared to sodium. This is due to an extra shell added. In the periodic table when you go down the group, the atomic radius increases due to increasing energy levels.
The atomic radius mean the distance from the center of the nucleus to the valance shell. it actually describes the size of the atom
