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?.
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:
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.

Two numbers differ by 8 if their product is 713 then the sum of the two numbers is.
The sum of the two numbers is equal to 70.
Let the first number be x.Let the second number be y.In this exercise, you're required to find two numbers by translating the word problem into an algebraic expression and then solving for the unknown variables (x and y).
Translating the word problem into an algebraic expression, we have;
Two numbers differ by 8:
[tex]x-y=8[/tex] ....equation 1.
The product of the two numbers is 713:
[tex]xy=713[/tex] ....equation 2.
To calculate the sum of the two numbers:
First of all, we would solve for each of the unknown variables (x and y).
From eqn. 1, we have:
[tex]x=8+y[/tex] ....equation 3.
Substituting eqn. 3 into eqn. 2, we have:
[tex]y(y+8)=713\\\\y^2+8y=713\\\\y^2+8y-713=0[/tex]
Solving the quadratic equation by factorization, we have:
[tex]y^2-31y +23y-713=0\\\\y(y-31)+23(y-31)=0\\\\(y+23)(y-31)=0[/tex]
y = -23 or 31.
For the value of x, when y = 31:
[tex]x=8+31[/tex]
x = 39
Now, we can calculate the sum of the two numbers:
[tex]x+y=39+31=70[/tex]

What are Parents?
It would seem simple to define the term "parenting" as follows: Parenting is the act of nurturing, supporting, encouraging, directing, guiding, and loving a child or children from infancy to adulthood.
Consistency and routine are key components of good parenting, which provides kids with a sense of control. Redundancy becomes the goal for parents because good parenting emphasizes helping children become independent. A style of parenting that takes into account the age and developmental stage of the kid is good parenting.
The biological parents of a kid are typically the father and mother whose DNA the child carries. Although they do not need to be blood relatives, legal parents have a family link to the kid by law, such as in the case of an adopted child.
Hence, He would be beaten if he was ever late to work.

Composite functions are functions formed by combining multiple functions that may or may not be the same.
The composite function (f o g)(x) is -2x - 1
The functions are given as:
[tex]f(x) =-2x - 5[/tex]
[tex]g(x) = x - 2[/tex]
The composite function (f o g)(x) is calculated using:
[tex](f\ o\ g)(x) = f(g(x))[/tex]
Given that:
[tex]f(x) =-2x - 5[/tex]
Substitute g(x) for x in the above equation
[tex]f(g(x)) =-2g(x) - 5[/tex]
Substitute [tex]g(x) = x - 2[/tex]
[tex]f(g(x)) =-2(x - 2) - 5[/tex]
