Answer:
There are 1.51 x 1024 molecules of carbon dioxide in 2.50 moles of carbon dioxide.
Explanation:
Answer:
17,890 J
Explanation:
The amount of heat released by a gaseous substance when it condenses is given by the formula
![Q=n\lambda_v](https://tex.z-dn.net/?f=Q%3Dn%5Clambda_v)
where
n is the number of moles of the substance
is the latent heat of vaporization
The formula can be applied if the substance is at its vaporization temperature.
In this problem, we have:
n = 0.440 mol is the number of moles of steam
is the latent heat of vaporization of water
And the steam is already at 100C, so we can apply the formula:
![Q=(0.440)(40660)=17,890 J](https://tex.z-dn.net/?f=Q%3D%280.440%29%2840660%29%3D17%2C890%20J)
Answer:
you need to include the bottom portion, not enough info
Explanation:
I would say that B is the correct answer which means that the melting point would be intensive or that no matter how large or small the sample of the sulphur is, it will have a consistent melting temperature or of 115.2 degrees C.
