calculate the mass of HNO3 obtained when 20.0g of KNO3 reacts completely with excess concentrated H2SO4

Chemistry
1 answer:

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

Why is it important to know what temperature scale is being used in a given situation?
Arisa [49]
It depends, for example, it is quite important to know the Kelvin scale (i.e 0 degrees Celsius is 273 K and -273 degrees Celsius is 0 K ) when dealing gases. But I don't know other situations where you would need to know other temperature scales.

Hope this helps and also if you are using Fahrenheit 1 Fahrenheit is -17.22 degrees Celsius

What are two methods to solve the energy crisis?​
grin007 [14]

Possible Solutions to the Problem of Global Energy Crisis
Move Towards Renewable Resources. ...
Buy Energy-Efficient Products. ...
Lighting Controls. ...
Easier Grid Access. ...
Energy Simulation. ...
Perform Energy Audit. ...
Common Stand on Climate Change. We've got to reduce our dependence on foreign oil; it's a matter of homeland security. Fine. Nobody's arguing. But the solutions that get offered -- drilling in ANWR, mandating better automobile fuel efficiency, pushing ethanol -- don't really solve anything. They're politically impossible, or too expensive, or contrary to free-market forces. They're losers.
Energy-independence advocate Gal Luft looks for winners. The former lieutenant colonel in the Israel Defense Forces and counterterrorism expert fervently believes that the only way to make America safe is to make it energy independent. And so as executive director of the Institute for the Analysis of Global Security and cofounder of the Set America Free Coalition, he has set out to do just that.

Luft advises Congress and security companies. He briefs industrial and environmental groups. Yet what separates him from other energy specialists are his pragmatic solutions. He doesn't peddle pie-in-the-sky political strategies. He's a realist. He has a single goal: freeing America from the grip of foreign oil. And he wants to do it now. At right are four steps he says we can -- and should -- take today.
