8) solubility of compound can be decided from solubility table which gives idea on soluble and insoluble salts. Mostly salts with actetate ions ( CH3COO-) , 1st group cations like Rb , are soluble. AgCl is only insoluble salt here
9) Real gases behave like ideal gas at high temperatures and low pressures . among given Ne at STP has reasonabley high tempa and low Pressure and also Ne is inert gas which doesnot have strong intermolecular forces of attraction. This makes Ne more closer to ideal gas
10) Acid is H+ donor. Hence CO2 must come from base which has C and O. The only option we have is CaCO3
The equation is 2HCl + CaCO3 ---> CaCl2 + H2O + CO2
11) an^2/V^2 is correction term for pressure. Pressure changes when there are moleuclar attractions. Hence this term is corrects for deviation from ideality due to moleuclar attractions
12) London forces or dispersion forces are the intermolecular forces are phenomenon where
