in the reaction :N2 + 3H2----2NH3 how many grams of H2 are needed to produce 1 mole on ammonia
The number of grams that are needed to produce 1 mole on ammonia is to be considered as the 1.52 g Hz.
Calculation of the number of grams:Here we begins the moles of ammonia for production after this it convert the number of moles of h2 for getting one mole of ammonia and then finally convert into grams
So it be like
[tex]= 1\ mol NH_3 \frac{3H_2}{2NH_3}\frac{1.01g }{1\ mol H_2}[/tex]
= 1.52 g Hz
Hence, The number of grams that are needed to produce 1 mole on ammonia is to be considered as the 1.52 g Hz.

When energy is released by the pack, what happens to the energy of the surroundings (outside the pack)?
a. The energy increases
b. The energy decreases
c. The energy stays the same
Answer:
a
Explanation:
i hope that's correct
The energy of the surroundings (outside the pack) will:
a. The energy increases, when energy is released.
Energy in the surroundings:Energy is delivered to create bonds, which is the reason the enthalpy change for it is positive to break bonds. Energy is expected to break bonds. Particles are a lot more joyful when they are "wedded" and discharge energy since it is simpler and more steady to be seeing someone.
When energy is released, the energy in the surroundings will increase.
Thus, option a is correct.
