<span>As the moisture-rich air approaches the mountain, it rises and cools, and water molecules in the air combine to form small drops. The process where water vapor becomes a liquid is called condensation. </span>
Uhm ireifjfjeifjdkedi the answer is...you hahahahahaha
A chemical equation is only balanced once there are equal numbers of all types of element on both sides of the equation
The mass of HNO3 obtained is 12.46 g from the given reaction.
The chemical reaction is :
Potassium Nitrate + Sulphuric acid ------> Potassium Bisulphate + Nitric acid.
The above reaction is basically used for the making of nitric acid.
Less than 200 degree celcius the Nitric acid if more than 200 degree celcius then it will form Potassium Sulphate.
Now,
1 mol of KNO3 reacts with1 mol of concentrated H2SO4 to give 1 mol HNO3
Molar Mass of KNO3 = 101.1 g
Molar mass of H2SO4 = 98.07 g
Mass of H2SO4 that can react with 20 g of KNO3 = (20 g* 98.07 g )/ 101.1 g
= 19.4 g
Molar mass of nitric acid= 63.01 g
Hence mass of nitric acid produced by 20 g of KNO3 = (20 g * 63.01 g ) / 101.1 g = 12.46 g
