One of the researchers proposes using oxygen gas production to measure reaction rates. Which of the following statements best justifies the use of the proposed modification as a way of creating an appropriate control for the investigation?.

Answers

Answer 1

There are different factors taken into consideration in production process. The statement that best justifies the use of the proposed modification as a way of creating an appropriate control for the investigation is that;

The experiment can be repeated without the use of guaiacol, which will therefore show the effect of guaiacol on the reaction rates.

Oxygen is an element that exist naturally and can also be produced from different kinds of materials. This is often done by using a lot of different methods.

The natural method of getting oxygen is through photosynthesis where plants are known to use sunlight to convert carbon dioxide in the air into oxygen.

By not using guaiacol again when repeating the same experiment, one can therefore know if the guaiacol in one or different ways affect the chemical reaction of the elements.

Answer 2

Answer:

C. The experiment can be repeated without guaiacol, which will reveal the effect of guaiacol on the reaction rates.

Explanation:

In the original experiment, the researchers used guaiacol as a reaction indicator. By using oxygen gas production to measure reaction rates, the researchers no longer need the guaiacol and can repeat the experiment without it, which will reveal the effect of guaiacol on the reaction rates.

Answers

The domain of a function is the set of input values the function can take

The radical function is not given; so, I will provide a general explanation

Assume the radical function is:

[tex]f(x) = \frac{1}{\sqrt{12- 2x}}[/tex]

The denominator of the above function cannot be negative.

So, we express the denominator as follows

[tex]12-2x > 0[/tex]

Subtract 12 from both sides

[tex]-2x > -12[/tex]

Divide both sides by -2

[tex]x < 6[/tex]

So, the possible values of x the function can take are less than 6

Hence, the domain of the radical function is [tex][-\infty,6][/tex]
