Suppose the price of gasoline increases 10% and quantity of gasoline demanded in Orlando drops 5% per day. Demand for gasoline i
grin007 [14]

Answer:

The correct answer is;

Demand for gasoline in Orlando is price inelastic.

Explanation:

The elasticity is the degree of response to a change in price or quantity supplied to the the quantity demanded. An elastic demand responds positively to change in price, while an inelastic demand means that when there is a price increase, the quantity demanded remains the same and where there is a drop in price the quantity demanded remains constant.

If a small change in price results in a large change in demand then the good is said to be price elastic

In the question the price increases by 10% while the quantity demanded drops 5 % daily. Therefore it is price inelastic

2-butanone is converted into 3-methyl-3-hexanol using a grignard reagent prepared from 1-bromopropane and magnesium metal in thf
Andre45 [30]

Answer:

Here's what I get.

Explanation:

At the end of the reaction you will have a solution of the alcohol in THF.

The microdistillation procedure will vary, depending on the specific apparatus you are using, but here is a typical procedure.

  • Transfer the solution to a conical vial.
  • Add a boiling stone.
  • Attach a Hickman head (shown below) and condenser.
  • Place the assembly in in the appropriate hole of an aluminium block on top of a hotplate stirrer.
  • Begin stirring and heating at a low level so the THF (bp 63 °C) can distill slowly.
  • Use a Pasteur pipet to withdraw the THF as needed.
  • When all the THF has been removed, raise the temperature of the Al block and distill the alcohol (bp 143 °C).

The digit that would have to be estimated in reading this instrument would be the nearest:
wariber [46]

Answer:

The least count of vernier calipers is 0.01 g.

(B) is correct option.

Explanation:

Given that,

The digit that would have to be estimated in reading this instrument,

According to figure,

We need to calculate the pitch

Using formula of pitch

pitch=\dfrac{distance\ moved}{Number\ of\ complete\ rotation}

Put the value into the formula

pitch=\dfrac{1}{10}

pitch=0.1\ g

We need to calculate the least count of vernier calipers

Using formula of least count

Least\ count=\dfrac{pitch}{number\ of\ vernier\ scale\ division}

Put the value into the formula

Least\ count=\dfrac{0.1}{10}

Least count = 0.01\ g

Hence, The least count of vernier calipers is 0.01 g.

(B) is correct option.

A scientist develops a new experiment to test atomic theory. His results do not agree with the theory.
slamgirl [31]

Answer:

When the results of a new experiment to test atomic theory do not agree with the theory, scientist will repeat the experiment to make sure that his results are reliable.

Explanation:

In the scientific context, each new experiment must be performed with precision and following the steps of the scientific method.

An experiment that does not provide reliable data to demonstrate a theory must be reviewed in detail and performed again to confirm the data obtained in the first attempt.

A theory is a postulate that tries to explain a natural phenomenon, but whose argument can be discussed or does not have the acceptance of a law. When the theory is proven and there are no arguments against it, it can be universally accepted and becomes a law.

The other options are not valid due to:

  • <u><em>Scientists worldwide will reject atomic theory because of the new results</em></u><em>.  A theory cannot be discarded without solid arguments or evidence in order to dismiss it and establish a new one.</em>
  • <u><em>The scientist will change his results to agree with the accepted theory</em></u><em>.  This would be an unethical procedure and unacceptable to the scientific community.</em>
  • <em><u>Other scientists will reject the results because they do not agree with the theory</u></em><em>. The opinion of other scientists is not enough to dismiss a theory, if it has a valid scientific basis.</em>
