Are you wanting us to answer all of them I will tell you in the comment box the answer ok
The industrial synthesis of ammonia is spontaneous.
to to prove this one calculate the gibbs free energy(delta G)
= delta G = Delta H -T delta s
delta H = -92.2 kj in joules -92.2 x1000 =-92200j
delta s = -199j/k
T= 25+273= 298k
delta G is therefore= -92200-298(-199)=-32898j
since delta G is negative the reaction is therefore spontaneous

Answer:
15%
Explanation:
From the question given above, the following data were obtained:
Mass of sugar = 15 g
Mass of water = 85 g
Percentage of sugar in the solution =?
Next, we shall determine the mass of the solution. This can be obtained as follow:
Mass of solute (sugar) = 15 g
Mass of solvent (water) = 85 g
Mass of solution =?
Mass of solution = mass of solute + mass of solvent
Mass of solution = 15 + 85
Mass of solution = 100 g
Finally, we shall determine the percentage of the sugar in the solution. This can be obtained as follow:
Mass of solute (sugar) = 15 g
Mass of solution = 100 g
Percentage of sugar in the solution =?
Percentage = solute /solution × 100
Percentage = 15 / 100 × 100
Percentage of sugar in the solution = 15%
The electrons fill energy levels from the lowest available energy level, based of three typical rules.
1) Follow Aufbau rule: fill from lower to higher energy levels (1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p)
2) Pauly exclusion principle: two electrons can not have the same four quantum numbers
3) Hund rule: if the orbitals have the same energy, the electrons must go to different orbitals before two occupies the same orbital.
