Answer:
Chloroform is expected to boil at 333 K (60
).
Explanation:
For liquid-vapor equilibrium at 1 atm,
= 0.
We know,
, where T is temperature in kelvin scale.
Here both
and
are corresponding to vaporization process therefore T represents boiling point of chloroform.
So, ![0=(31.4\times 10^{3}\frac{J}{mol})-[T\times (94.2\frac{J}{mol.K})]](https://tex.z-dn.net/?f=0%3D%2831.4%5Ctimes%2010%5E%7B3%7D%5Cfrac%7BJ%7D%7Bmol%7D%29-%5BT%5Ctimes%20%2894.2%5Cfrac%7BJ%7D%7Bmol.K%7D%29%5D)
or, T = 333 K
So, at 333 K (60
) , chloroform is expected to boil.
Answer:
squirrels play a essential role in the food chain as prey and predator they provide nutrition different organisms in habitats and promoting their predator
Explanation:
that's what the role is
Answer:
m = 79.1 grams
Explanation:
Given that,
Density, d = 2.26 g/mL
Volume occupies, V = 35 mL
We need to find the mass of the substance. We know that the density of an object is equal to the mass per unit volume. So,
d = m/V

So, the mass of the substance is 79.1 grams.
Answer:
166.56g of NH3 are produced
Explanation:
The reaction of N2 with H2 to produce NH3 is:
N2 + 3H2 → 2NH3
<em>Where 1 mole of N2 produce 2 moles of NH3</em>
<em />
4.89 moles of N2 with excess of H2 produce:
4.89 moles N2 * (2 moles NH3 / 1 mole N2) = 9.78 moles NH3
As molar mass of NH3 is 17.031g/mol, mass of NH3 produced is:
9.78 moles * (17.031g / mol) =
<h3>166.56g of NH3 are produced</h3>
