Explanation:
C. Nobel gas are very stable because in their valance shell maximum number of electrons are present
Condensation happens<span> when the temperature of air containing moisture decreases. falling air temperatures cause condensation because warm air can hold more moisture than </span>cold<span> air. when warm air in the </span>bathroom<span> is heated by the shower to temperatures as much as 100 degrees F, the air becomes saturated with moisture, hope it helps</span>
I would say it’s the last answer . D. I would say this because the Germans took the Jews belongings like gold, money, jewelry, anything they had and they kept it to themselves so the Jews didn’t have anything valuable . Even their clothes.
The balanced combustion reaction for one mole of ethane will be
C2H6 + 3.5 O2 ---> 2CO2(g) + 3H2O (l)
Enthalpy of reaction of combustion = ∑ΔHf (products)- ∑ΔHf (reactant)
ΔHf = enthalpy of formation
The enthalpy of formation of oxygen = 0 as it is an element in its native state
ΔHf C2H6 = -83.820 kJ / mole
ΔHf H2O = -285.830 kJ / mole
ΔHf CO2 = -393.509 kJ / mole
ΔHrxn = [2 X ΔHf CO2 + 3 X ΔHf H2O] - [ΔHf C2H6]
ΔHrxn = [2 X (-393.509) + 3 (-285.830)] - [-83.820]
ΔHrxn = -1560.688 kJ / mole
