According to this formula when:
ΔG = ΔH - TΔS = 0
∴ ΔS = ΔH/T
∴ ΔS = n*ΔHVap / Tvap
- when n is the number of moles = mass/molar mass
when the mass = 24.1 g
and the molar mass = 187.3764 g/mol
by substitution:
∴ n = 24.1 / 187.3764g/mol
= 0.129 moles
and ΔHvap is the molar enthalpy of vaporization is 27.49 kJ/mol
and Tvap is the temperature in Kelvin = 47.6 + 273 = 320.6 K
So by substitution, we will get the ΔS the change in entropy:
∴ΔS = 0.129 mol * 27490 J/mol / 320.6 K
= 11 J/K
The best description of bond angles around the carbon atoms of 1-butene is double bonded unsaturated carbon atoms and sp2 hybridized

The number of moles in a substance may be calculated using:
Moles = mass / molecular mass
The molecular mass of CH₂Cl₂ is:
12 + 2 * 1 + 2 * 35.5
= 85 grams / mole
Moles = 76.1 / 85
Moles = 0.895
There are 0.90 moles of CH₂Cl₂ present in 76.1 grams.
Answer:
C) 2, 4.
Explanation:
Hello!
In this case, since the sulfur atom has six electrons at its outer shell, it suggests it needs to gain two electrons in order to attain a complete octet, that is why it has 2 paired electrons.
Moreover, since two electrons are paired, then 4 electrons will remain unpaired; therefore the answer would be C) 2, 4.
Best regards!
Answer:
It takes 7 mol H2 to produce 7 mol H2O
Explanation:
In 2H2O, there's 2 moles of H2 for every 1 mol O2.
So, if oxygen is limiting you'd only be able to produce 2 moles of H2O. I don't know if the question implies that, so it could also be that 7 mol H2 makes 7 mol H2O. Sorry for the confusion, I hope it helps a bit
