A] 1 N2 + 3 H2 → 2 NH3 1. How many moles and grams of ammonia can be made from 6.3 moles of H2 ?

2. How many moles and particles of ammonia can be made from 2.5 moles of N2 ?

3. How many moles is 425 g of ammonia? How many moles and grams of N2 are needed to make it?

4. How many moles and grams and liters of H2 are needed to make 10 moles of ammonia?

what are the two models

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
