Example class 11 and 12 chemistry quiz questions

Which quantum number determines the shape of an orbital?The azimuthal (angular momentum) quantum number, l. It sets the subshape (s, p, d or f), while n sets the energy level.

What is the molar mass of CO2 (C = 12 g/mol, O = 16 g/mol)?44 g/mol. One carbon at 12 plus two oxygen atoms at 16 each gives 44.

True or false: a 0.01 M HCl solution has a pH of 2.True. HCl is a strong acid that fully dissociates, so [H+] = 0.01 M and pH = -log(0.01) = 2.

Why does ethanol have a higher boiling point than ethane?Ethanol forms hydrogen bonds between molecules, which take more energy to break than the weak van der Waals forces in ethane.

For N2 + 3H2 ⇌ 2NH3, what happens to equilibrium when pressure is increased?It shifts toward ammonia, because the side with fewer gas moles (2 versus 4) is favored under higher pressure.
