Previously in this lesson it was mentioned that, according to some reports, in the past 35 years, world oil consumption has grow

n about 45% and continues to rise. Although crude oil, or petroleum, is a natural resource, it is nonrenewable and must undergo an expensive refining process before people can use it to power their cars. Respond to this statement by describing two potential effects of such a rise in oil consumption. Also, indicate whether or not you are confident that there will be ample alternative fuels to use if we drain the oil supply.

<span>First potential effects of such a rise in oil consumption.

The first and most important potential effect could be the drain of all oil, causing an effect on our lives and on the market that could be nearly catastrophic, due to the collapse of the offer that would influence nearly all sector of the economy with a downfall which consequences are impossible to foreseen but it is possible to tell they would not be pleasant.
----
</span>Second potential effects of such a rise in oil consumption. 

The second potential effects could be the fact that as oil becomes rarer and harder to get, would also get more expensive, with a repercussion on our lifestyle that would cause many people to either lose their job or not be able to afford a car or anything powered by oil. Without valid alternatives, some sectors could experience an economic crisis of great proportion.

Am I confident that there will be ample alternative fuels to use if we drain the oil supply?

Yes, I am confident that there will be ample alternative fuels to use if we drain the oil supply. Solar and wind fuels are the future in the sector of energy, not only because oil is a non-renewable resource, but for climatic purpose too since oil is one of the greatest contributors to the human-made global warming that we are experiencing right now.

1. a.) Calculate the wavelength of light which has a frequency of 5.25 x 10 14 Hz.
Scilla [17]
<h3>Answer:</h3>

5.71 × 10² nm

<h3>Explanation:</h3>

The product of wavelength and frequency of a wave gives the speed of the wave.

Therefore;

Velocity of wave = Wavelength × Frequency

c = f ×λ

In our case;

Frequency = 5.25 × 10^14 Hz

Speed of light = 2.998 × 10^8m/s

But;

λ = c ÷ f

  = 2.998 × 10^8m/s ÷  5.25 × 10^14 Hz

  = 5.71 × 10^-7 m

But; 1 M = 10^9 nm

Therefore;

wavelength = 5.71 × 10^-7 × 10^9

                  = 5.71 × 10² nm

The wavelength of light wave 5.71 × 10² nm

In the partition coefficient experiment 4A this week, after thorough mixing of the reagents, phase separation will occur. The to
Andreas93 [3]

Answer:

The top layer is the Aqueous layer, and the benzoic acid is contained in the non-aqueous layer/oil phase.

Explanation:

A separating funnel is a very important piece of laboratory glassware that is used to separate the components of liquid-liquid mixtures  which are immiscible. This technique is used in the extraction of the components of mixtures.

The liquids separate into two phases. The separation is based on the differences in the liquids' densities, where the denser liquid settles below and the lower density liquid stays afloat. Liquids used for this kind of separation are usually different liquids, one is the aqueous layer and the other, a non-aqueous layer.

Partition coefficient or distribution coefficient is defined as the ratio of the concentrations of a compound in two immiscible solvents at equilibrium.

Organic solvents (except halogenated organic compounds) with densities greater than that of water i.e 1g/mL ( usually called the oil phase) settle at the bottom of the aqueous phase.

Benzoic acid. will settle at the bottom layer ( i.e the lower phase).

A certain hydrocarbon has a molecular formula of C9H16. Which of the following is not a structural possibility for this hydrocar
snow_tiger [21]

Answer: Option (d) is the correct answer.

Explanation:

It is given that molecular formula is C_{9}H_{16}. Now, we will calculate the degree of unsaturation as follows.

Degree of unsaturation = C_{n} - \frac{\text{monovalent}}{2} + \frac{\text{trivalent}}{2} + 1

                                  = 9 - \frac{16}{2} + 1

                                  = 9 - 8 + 1

                                  = 2

As the degree of unsaturation comes out to be 2. It means that this compound will contain one ring and one double bond.

Yes, this compound could be an alkyne as for alkyne D.B.E = 2.

But this compound cannot be a cycloalkane because for a cycloalkane D.B.E = 1 which is due to the ring only.

Thus, we can conclude that it is a cycloalkane is not a structural possibility for this hydrocarbon.
