1. What is an isomer? How many possible isomers of hexane are there? What are the structural differences between these isomers?
UNO [17]
When two compounds have same molecular formula but different structural formula, they are said to be isomers of each other and this phenomenon is called as isomerism. 

Hexane has six isomers.

The isomers of hexane have a difference in their structure due to parent chain length (chain isomerism). They are also differentiated on the basis of straight chain as in n-hexane and branched chain as in remaining five. Structures along with names are shown below.

A mixture of nitrogen gas and oxygen gas has a total pressure of 123.5 kPa. If the
ASHA 777 [7]

Answer: 19kpa

Explanation:

The total pressure of a mixture of gases is the sum of the partial pressure exacted by the individual gases.

P total = P X + P Y

From the question above:

P total = P .nitrogen + P. oxygen

123.5kpa = 104.5kpa + P. Oxygen

P. Oxygen = 123.5kpa - 104.5kpa

= 19kpa

Which idea behind the shape of molecules includes the concept that electrostatic repulsion between electron pairs surrounding an
Vladimir79 [104]

Answer:

VSEPR theory

Explanation:

The valence shell electron pair repulsion theory was propounded by Gillespie and Nylom (1957).

The entire idea of the VSEPR theory is that the shape of a molecule depends on the electrostatic repulsion between electron pairs surrounding the central atom in a molecule which causes these pairs to be separated as far as possible.

The shapes of many molecules can be accurately predicted based on this model.
