Answer:

The answer is boiling point.

Explanation:

The boiling point of a substance refers to the temperature at which the vapour pressure of a liquid equals the atmospheric pressure; at this point the liquid will boil. Different liquids have different boiling points that are unique to them. This makes it possible for scientists to use boiling points as one of the criteria by which a liquid substance can be identified. At boiling point, the chemical bonds that are holding liquid particles together are destroyed and the liquid turn to gas.

If a molecule can hydrogen bond does it guarantee that it will have a higher boiling point than a molecule that cannot?

A molecule that can h-bond will not always necessarily and does not have guarantee to have a higher boiling point than one than cannot have h-bond.
we can take an example of Pentan-2-one that cannot h-bond but instead of this it  has a high boiling point that is 102.3 °C, while propan-1-ol can h-bond but it has a boiling point of 97.2°C, that is lower than the boiling point of Pentan-2-one.

Vinegar contains carbon, hydrogen, and oxygen with percent masses of 40.01% C, 6.70% H, and 53.29% O, respectively. Determine th
kobusy [5.1K]

The empirical formula is = C2H4O2

Molecular formula=C2H4O2

<h3>Calculation of Molecular formula and empirical formula:-</h3>

Vinegar has three elements:

oxygen = 53.29%,

hydrogen = 6.70%,

and carbon = 40.01%.

We can create an equation for the total mass of vinegar with 'a' carbon atom,' b' hydrogen atom, and 'c' oxygen atoms using the molar masses of C, H, and O.

12*a + 1*b + 16*c = 60

We also know that C makes up 24 g/mol, or 40.01 percent, of the overall mass of 60 g/mol.

The formula contains two C atoms because each C atom has a molecular mass of 12 g/mol. You may determine that the formula contains 4 H and 2 O atoms by using the same reasoning for H and O.

The empirical formula is = C2H4O2

Molecular formula= (C2H4O2)n

(4 x 12 + 1 x 4 + 16 x 2)n = 60

(84)n = 60

n=60/84

n=0.71=1

Molecular formula=C2H4O2

Balanced equation: SiO2 + 4 HF --&gt; SiF4 + 2H2O
Arlecino [84]
C. 25 Miles

This is because you have 12.5 moles of water and using the ratio this is 2 (molar ratio). Therefore the molar ratio for HF is 4, so 12.5 x 2 = 25 moles
