Crude petroleum is a mixture of many different components. how might one separate out the components to begin the process of refining petroleum? what property does this separation technique depend on? (2 points)

To separate out the components of crude oil, the process of fractional distillation is used. This process involves using distillation to separate a mixture of liquids into different parts according to the boiling point. Every component of crude oil has its own boiling point, hence to separate them, the process fractional distillation is used. This separation techniques depend on the boiling point (temperature) of these components as heat is applied.

Explanation:

the correct answer is modern american cars are not available due to trade restrictions.

trade between cuba and the united states have serious restrictions. the u.s. imposed an economic embargo on cuba, that among other things means that modern american cars are not available due to trade restrictions.

in response to some governmental actions of the authorities from cuba, president john f. kennedy proclaimed an embargo on trade between both countries in february 1962. the trade embargo remains active until this day and was implemented directly by the departments of commerce and the department of treasury.

in president trump’s administration, there is a national security presidential memorandum that "strengthens the policy of the u. s.", affecting trade with cuba.
