What is the solubility of methylacetylene (in units of grams per liter) in water at 25 °C, when the C3H4 gas over the solution h
Luda [366]

Answer:

The solubility of methylacetylene is 0,11 g L⁻¹

Explanation:

Henry's law is a gas law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid.

The formula is:

C = kH P

Where C is solubility of the gas (In mol/L)

kH is Henry constant (9,23x10⁻² mol L⁻¹ atm⁻¹)

An P is partial pressure (0,301 atm)

Solving, C = 2,78x10⁻³ mol L⁻¹. In grams per liter:

2,78x10⁻³ mol L⁻¹ₓ \frac{40 g}{mol} = <em>0,11 g L⁻¹</em>

<em></em>

I hope it helps!

How many moles of carbon are in 25 grams of carbon
Brut [27]

Answer:

One mole of carbon would look like 25/12.01

Explanation:

Firstly, you will divide 25 by 12.01 and get 2.081598  

We know 1 mole equals the gram per atomic mass,  so one mole of carbon is 12.01 grams. In conclusion, it would look like 25/12.01.

Why is it important to know what temperature scale is being used in a given situation?
Arisa [49]
It depends, for example, it is quite important to know the Kelvin scale (i.e 0 degrees Celsius is 273 K and -273 degrees Celsius is 0 K ) when dealing gases. But I don't know other situations where you would need to know other temperature scales.

Hope this helps and also if you are using Fahrenheit 1 Fahrenheit is -17.22 degrees Celsius

Which of the following is true about nuclear fusion
Sonja [21]

Answer:

 i would assume that it would be (a)

Explanation:

The Sun generates its energy by nuclear fusion

NUCLEAR FISSION is when the heavy atom is split

fusion energy is scientifically feasible. Plasma conditions that are very close to those required in a fusion reactor are now routinely reached in experiments

mass gets lost is nuclear fusion

so (a) is the most accurate
