HCl(aq) + KOH(s) --> KCl(aq) + H2O(l)
The answer is A because Alkaline are gases in earth's atmosphere <span />
Molar mass of N = 14 g/molMolar mass of O2 = 32 g/molAdding both masses = 46 g/molActual molar mass/ Empirical molar mass = 138.02 / 46 = 3Now multiplying this co effecient with empirical fomula NO2 = 3(NO2) = N3O6So according to above explanation,D) N3O6, is the correct answer.
Answer:
reactivity:very reactive,less reactive
density:float in water,sink in water
melting and boiling point:low,high
colour of salts: colourless,often coloured
