The answer is, "1 molecule of nitrogen reacts with 3 molecules of hydrogen to give 2 molecules of ammonia."

Considering the reaction:

N₂ + 3 H₂ ------> 2 NH₃.

As this can be seen from the reaction that, "1 molecule of nitrogen reacts with 3 molecules of hydrogen to give 2 molecules of ammonia."

So the answer is that "1 molecule of nitrogen reacts with 3 molecules of hydrogen to give 2 molecules of ammonia."

The reducing agent is donating electrons and therefore becoming oxidised itself. In this scenario elemental zinc (Zn) is in a reduced state and is oxidised to become Zn2+, in doing so it donates electrons to Fe2+, thereby reducing it to elemental iron (Fe).

The elemental Zinc in solid state is therefore the reducing agent as it reduces Fe2+ to Fe(s).

*<br> What is the volume, in liters, of 12.0 kg of H2 at STP?
neonofarm [45]

Answer:

According to Avogadro's law, the volume of one mole of any gas at Standard Temperature and Pressure (STP = 273 K and 1 atm) is 22.4 L. Two important Gas Laws are required in order to convert the experimentally determined volume of hydrogen gas to that at STP. 1.

Briefly compare and contrast the relative resistance to ph change of the seven solutions
JulsSmile [24]
PH  stands for "Potential Hydrogen" and the PH scale ranges from 0-14. PH refers to the ability to attract hydrogen ions.

The PH of a solution either indicates acidity of the solution or alkalinity of the solution. A solution which has PH 7 above is a base solution where a solution with PH less than 7 is an acidic solution.

Thallium consists of 29.5%Th-203 and 70.5%Th-205. What is the relative atomic mass of thallium?
grin007 [14]
0.295 * 203 = 53.885
0.705 * 205 = 144.525
53.885 + 144.525 = 204.41
The relative atomic mass of Thallium is 204.41
