Increasing alternative energy sources
zavuch27 [327]3 years ago

1) Answer is: a.increasing alternative energy sources.

For example, using more biofuels derived directly from plants or solar energy.

Biofuel is renewable energy source, but not green energy source. Green energy does not harm ecosystems, contribute to acid rain, or worsen global warming. Biofuels produce greenhouse gases (carbone dioxide, methane).

Solar radiation is the source of electric energy.

2) Answer is:

a) Separation.

Crude oil is mixture (solution) consist of several different hydrocarbons (alkanes, alkenes...).

This hydroalkanes can be separated from mixture (crude oil) using distilation (usually fractional distillation), because they have different boiling points.

b) Conversion.

Hydrocarbons with bigger molecular mass are split into lighter ones.

c) Treatment.

For example gasoline, diesel fuel and heating oil are made.

What causes competition?
zvonat [6]

Explanation:

Competition stems from the fact that resources are limited. There are simply not enough of some resources for all individuals to have equal access and supply. Competition can occur between organisms of the same species, or between members of different species.

gasoline is separated from crude oil by heating it until it reaches it's boiling point. which separation method is used?​
Orlov [11]

Answer:

Fractional distillation

Explanation:

The separation of gasoline from crude oil by heating until it reaches its boiling point is a separation technique called fractional distillation.

  • It is the separation of a mixture, such as crude oil into their respective fractions.
  • This is achieved due to the differences in boiling point between the constituent fractions in the mixture.
  • As the boiling point of a fraction is reached, it distills out from the column.

Imagine you leave a bottle of something toxic to humans open overnight in a sealed laboratory.
IgorC [24]

Answer:

Argument: It is not Safe

Further support to the argument is given below.

Explanation:

Solution:

Argument: It is not Safe

First of all, we all know the ideal gas law:

PV = nRT

And the Boyle's Law states that , if the pressure is increased then, volume will decrease. and if the volume is increased then pressure will decrease.

V is inversely proportional to Pressure of the gas.

So, in this case, Let's suppose we have toxic solution of methyl alcohol in the bottle which is tightly closed. It means pressure in the bottle is high, hence the volume is less.

If in this scenario someone, leave the bottle open in the laboratory and as it is given that the level of solution will drastically decrease. It means it is volatile in nature and is converted into gaseous form and we know now that the open bottle has now less pressure. Hence the volume of the gas will be higher and now it can spread to every corner of the laboratory. And it is very dangerous.
