Answer:
Mass = 15.13 g
Explanation:
Given data:
Number of atoms of hydrogen = 8.11×10²³
Mass of ammonia formed = ?
Solution:
Chemical equation:
3H₂ + N₂ → 2NH₃
Number of moles of hydrogen:
1 mole contain 6.022× 10²³ atoms
8.11×10²³ atoms × 1 mol / 6.022× 10²³ atoms
1.35 mol
Now we will compare the moles of hydrogen and ammonia:
H₂ : NH₃
3 : 2
1.35 : 2/3×1.35 = 0.89 mol
Mass of ammonia:
Mass = number of moles × molar mass
Mass = 0.89 mol × 17 g/mol
Mass = 15.13 g
E. A direct measure of internal kinetic energy
Produce a transmembrane proton electrochemical gradient as a result of the redox reactions. If protons flow back through the membrane, they enable mechanical work, such as rotating bacterial flagella.
Answer:
to mi understanding iz fusion reaction
Answer:
Melting is an example of an endothermic change.
Explanation:
This is because the system absorbs (heat) energy from the surroundings to increase its temperature.
