What is the relationship between density and boiling point

Chemistry
1 answer:
stiv31 [10]4 years ago
8 0

Answer:

A liquid in a vacuum has a lower boiling point than when that liquid is at atmospheric pressure. A liquid at high-pressure has a higher boiling point than when that liquid is at atmospheric pressure. In other words, the boiling point of a liquid varies depending upon the surrounding environmental pressure

Answer:  


AB is an ionic compound. The electronegativity difference between A and B is greater.  


AC is an ionic compound. The electronegativity difference between A and C is greater.  


BC is a covalent compound because the electronegativity difference between C and B is small.

80 liters of oxygen is collected over water at 50.0 degrees Celsius. The atmospheric pressure during the collection was 96.00 kp
vlabodo [156]

Answer:

The value of partial pressure of oxygen P_{O_{2} } = 83.66 K pa

Explanation:

Volume of oxygen = 80 liters

Temperature = 50°c

The total pressure = 96 K pa

The partial pressure of water at 50°c is calculated from the tables.

P_{H_{2}O } = 12.344 K pa

The total pressure is given by

P_{total} = P_{H_{2}O } + P_{O_{2} }

Put all the values in the above equation we get

96 = 12.344 + P_{O_{2} }

P_{O_{2} } = 96 - 12.344

P_{O_{2} } = 83.66 K pa

This is the value of partial pressure of oxygen.

dimulka [17.4K]

Answer:

Molecules are made of two or more atoms

Molecules are made of atoms of the same element or different elements.

Molecules range in size.

Explanation:

A molecule is formed whenever two or more atoms combine. Hence we can define a molecule as a combination of two or more elements that are combined chemically and can not be separated by any physical means.

Molecules may be composed of the same atoms as in O2, F2 etc or different atoms as in CO2, H2O, etc.

The sizes of molecules differ. Some molecules are quite small in size while others are quite large in size.
