Explanation / Answer

Q12

from reaction in eq 11:

2NO + O2 = 2NO2

raito is

2 mol o fNO2 = 1 mol of O2 = 2 mol of NO2

Q13

determine moles of NO required for 23 g of NO2

mol of NO2 = mass/MW = 23/46.0055 = 0.5 mol of NO2

ratio is 2:2 so

0.5 mol of NO2 = 0.5 mol of NO

Q14

AgBr is no likely to be soluble

since most silver halides ( i.e. Cl-,I-,Br-) are not soluble in water
