How does the flammability of a hydrocarbon change as its carbon length increases?

When the chain length of carbon increase the flammability decrease.


When you increase the length of your workout what are you increasing?

Length is measured in time. So, you are increasing the time of the workout.


Is a short-chain hydrocarbon more viscous than a long chain hydrocarbon?

Typically the shorter the carbon chain, the LESS viscous the hydrocarbon. The longer the chain, the MORE viscous the hydrocarbon. For example consider the viscosity and molecular size in: Gasoline < Diesel < Motor Oil < Tar Viscosity increases with the molecular size and length of hydrocarbon chain.


How does the volatility of a hydrocarbon change as its carbon chain length increases?

Disaccharide differ from each other in what ways?

differ by the length of the hydrocarbon chain, and if its saturated or unsaturated.


How is magnifying power of telescope and a microscope are a affected by increasing the focal length of their objectives?

The magnification of a telescope M is the the focal length of the objective Fo over the focal length of the eyepiece Fe so increasing the focal length of the objective increases the magnification. The magnification of a microscope M is approximately tube length L/Fo x 25/Fe. Therefore increasing the focal length of the objective reduces the magnification.
