Answer:

A. Vegetable oil

Explanation:

Solubility is determined by the principle , "like dissolves like" .

i.e. , if a compound is polar then it will dissolve in a polar compound only , and

if a compound is non - polar then it will dissolve in a non - polar compound only .

Hence , from the question ,

A. Vegetable oil is a non polar compound ,

B. Polar compound

C. ionic compound , is a polar compound .

Since , wate is polar in nature , hence it will get dissolved in a only polar compound ,

Therefore ,

Water will not get dissolved in vegetable oil , being it a non - polar compound .

Which of the following represents the correct ranking in terms of increasing boiling point? A. n-butane &lt; 1-butanol &lt; diet
bonufazy [111]

Answer:

The answer to your question is: letter E

Explanation:

Normally, the correct order of boiling points is:

                     Alcohols > Ketones > Ether > Alkane

Then

A. n-butane < 1-butanol < diethyl ether < 2-butanone

B. n-butane < 2-butanone < diethyl ether < 1-butanol

C. 2-butanone < n-butane < diethyl ether < 1-butanol

D. n-butane < diethyl ether < 1-butanol < 2-butanone

E. n-butane < diethyl ether < 2-butanone < 1-butanol

     (- 1°C)     <    34.6°C         <  79.64°C      <  117.7°C

What would the rate law be for the following reaction:
lana [24]

Answer:

C. Rate = k[H2]^2[O2]

Explanation:

Rate law only cares about REACTANTS. Since, rate law can only be determined experimentally, I am assuming the given reaction mechanism is elementary reaction from which we can write the rate law.

Only H2 and O2 are part of rate law since they are reactants and also the coefficient in front of H2 goes as exponent on rate law to indicate the order of H2 in the reaction.

Rate= k [H2]^2 [O2]

If it takes 100 N to move a box 5 meters, what is the work done on the box?
JulijaS [17]
<h3>Answer:</h3>

500 Joules

<h3>Explanation:</h3>

<u>We are given;</u>

  • Force is 100 N
  • Distance is 5 m

We are required to calculate the work done;

  1. Work done is the product of force and distance.
  2. That is, work done = Force × distance
  3. Work is measured in Joules

Thus, in this case;

Work done = 100 N × 5 m

                  = 500 Joules

Thus, the work done in moving the box is 500 joules
