When moist air cools below its dew point on a cold surface it forms dew. It is in the liquid state.
Rain is again a form of precipitation in which water is in the liquid state.
When air temperature is below freezing, the precipitation that results is referred to as frost. Hail is a form of precipitation in the ice balls whereas as sleet is a mixture of rain and snow.
N2 + 3H2 --> 2NH3 When 100g of N2 , no of moles of N2= 100/(28)=3.57 mol no. of moles of h2 = 6/(2)=3mol Therefore h2 is limiting reagent. no. of moles of ammonia= 3/3*2=2moles mass of ammonia produced= 2 mol * (14+3)= 34g
