Hydrocarbons consisting of short carbon chains are

a. more volatile than hydrocarbons with longer chains
b. more viscous than hydrocarbons with longer chains
c. typically stable in a solid state at room temperatures
d. more prone to tangling and bonding with each other

Option (A) is the correct answer.

Explanation:

Volatility is defined as the ability of a substance to readily evaporate into the atmosphere.

A small chain of hydrocarbon will have molecules in a small surface area. Moreover, a small chain hydrocarbon will have lesser dispersion forces due to which molecules are able to evaporate into the atmosphere easily.

Short carbon chain hydrocarbon will also be less viscous in nature.

Therefore, hydrocarbons consisting of short carbon chains are more volatile than hydrocarbons with longer chains.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
