Answer:
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.

Answer:
∆H° rxn = - 93 kJ
Explanation:
Recall that a change in standard in enthalpy, ∆H°, can be calculated from the inventory of the energies, H, of the bonds broken minus bonds formed (H according to Hess Law.
We need to find in an appropiate reference table the bond energies for all the species in the reactions and then compute the result.
N₂ (g) + 3H₂ (g) ⇒ 2NH₃ (g)
1 N≡N = 1(945 kJ/mol) 3 H-H = 3 (432 kJ/mol) 6 N-H = 6 ( 389 kJ/mol)
∆H° rxn = ∑ H bonds broken - ∑ H bonds formed
∆H° rxn = [ 1(945 kJ) + 3 (432 kJ) ] - [ 6 (389 k J]
∆H° rxn = 2,241 kJ -2334 kJ = -93 kJ
be careful when reading values from the reference table since you will find listed N-N bond energy (single bond), but we have instead a triple bond, N≡N, we have to use this one .
Answer:
Anita did not make the track team this year, and she feels really disappointed and upset. What question would most likely redirect her thinking and provide a solution?
Why did this terrible thing happen to me?
What other sports can I try this spring?
Why does everything I attempt go wrong?
Why did Karen get on the team but I didn't?
Answer - What other sports can I try this spring?
Explanation:
Failures and successes are part of our daily lives as humans. It can be very challenging for one to accept his or her failures and bring oneself above it.
when failure occur, the best way to reverse the negative impacts it brings is to move forward and decide on what next to do.
The actions that must be taken in the processes should be quite productive enough to bring back the results one desired.
When the effects of failures prove irreversible, one would then give the mind a diversion and help his or herself think their way though the failure that was encountered.
