BOBERT don’t u dare write a whole paragraph cause no one has time to read all that rn xoxo
Answer is: <span>B) -50.2 kJ.
Balanced chemical reaction: </span>N₂(g) + 3H₂(g) → 2NH₃(g) ΔH = -<span>100.4 kJ.
This is exothermic reaction, because heat is released and energy is include as product of chemical reaction.
Make proportion, two moles of ammonia released 100.4 kJ of heat, then one mole of ammonia released:
2 mol(NH</span>₃) : (-100.4 kJ) = 1 mol : ΔH.
ΔH = -50.2 kJ; <span>heat released per mole of NH</span>₃.
Answer:
500 moles
Explanation:
Given mass of SO2 = 32
Molar mass of SO2 =64
So, 32x10^8/64=500
In the first shell there is 2 electrons and on the second shell there is 4 elections.
