first you know that NO2 is mixed anhydride of HNO3 and HNO2 so actully Na2CO3 is alkali so if it reacts with NO2 so it form NaNO3 and NaNO2 as product similerly when it reacts with NaOH.

when water is added to lime ,a hissing sound is produced along with cloud of steam.large amount of heat liberated ,formation of Ca(OH)2 takes place.the process is known as slaking of lime.the paste of lime in water is called milk of lime while the filtered and clear solution is known as lime water.chemically both are Ca(OH)2
