How many grams of ammonia would be formed from the complete reaction of 4.50 moles hydrogen

51 grams of ammonia would be formed.

Explanation:

Moles of hydrogen gas = 4.50 moles

According to reaction, 3 moles of hydrogen gas gives 2 moles of ammonia gas.

Then 4.50 moles of hydrogen gas will give:

of ammonia

Mass of 3.00 moles of ammonia:

51 grams of ammonia would be formed.

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
