I think the answer is C but don’t quote me on that
Answer:
The answer is FALSE
Explanation:
I took the test and it was false,
also if it was true then in industrialized countries would be more eco-friendly and there wouldn't be a huge hole in our ozone layer. and no more wars over oil.
Answer:
34.02 g.
Explanation:
Hello!
In this case, since the gas behaves ideally, we can use the following equation to compute the moles at the specified conditions:
![PV=nRT\\\\n=\frac{1.00atm*0.960L}{0.08206\frac{atm*L}{mol*K}*(150+273)K} =0.0277mol\\\\](https://tex.z-dn.net/?f=PV%3DnRT%5C%5C%5C%5Cn%3D%5Cfrac%7B1.00atm%2A0.960L%7D%7B0.08206%5Cfrac%7Batm%2AL%7D%7Bmol%2AK%7D%2A%28150%2B273%29K%7D%20%3D0.0277mol%5C%5C%5C%5C)
Now, since the molar mass of a compound is computed by dividing the mass over mass, we obtain the following molar mass:
![MM=\frac{0.941g}{0.0277mol} \\\\MM=34.02g/mol](https://tex.z-dn.net/?f=MM%3D%5Cfrac%7B0.941g%7D%7B0.0277mol%7D%20%5C%5C%5C%5CMM%3D34.02g%2Fmol)
So probably, the gas may be H₂S.
Best regards!
Answer:
The answer is maybe reactivity
Answer:
16.0%.
Explanation:
Volume percent of a substance is the ratio of the substance volume to the solution volume multiplied by 100.
V % of ethanol = (volume of ethanol / volume of the solution) x 100.
volume of ethanol = 90.0 mL, volume of the solution = 550.0 mL.
∴ V % of ethanol = (90.0 mL / 550.0 mL) x 100 = 16.36% ≅ 16.0%.
