I know the answer. It is 2 straight chains. lLOL
Answer:
The answer is NO
Explanation:
In every compound, the sum of oxidation number between the elements is 0.
- In NO, nitrogen acts with +2 and oxygen as usual acts with -2
- In N₂O₃, nitrogen acts with +3 and oxygen, -2
- In NO₂, nitrogen acts with +4, and oxygen -2
- In N₂O, nitrogen acts with +1, and oxygen -2

Explanation:
Hello,
In this case, for the mole fraction of methanol we use the formula:

Thus, we compute the moles of both water (molar mass 18 g/mol) and methanol (molar mass 32 g/mol):

Hence, mole fraction is:

Next, mass percent is:

And the molality, considering the mass of water in kg (0.185 kg):

Regards.
Charles law states that for a fixed mass of gas at constant pressure the volume of the gas is directly proportional to the temperature in Kelvin scale
v1/T1 = v2/T2
Where v1 is volume and T1 is temperature at the first instance
v2 is volume and T2 is temperature at the second instance
Substituting the values in the equation
0.5 L / 203 K = v2 / 273 K
v2 = 0.672 L
The volume of Air after heating is 0.672 L
Option 2 is the correct answer
