Answer:
proportional. having a constant ratio. Second law: A body of mass m subject to a net force F undergoes an acceleration a that has the same direction as the force and a magnitude that is directly proportional to the force and inversely proportional to the mass, i.e., unbalanced.

The correct answer that would best complete the given statement above would be the word MIXTURE. <span>A substance which contains various elements or compounds without bonding or in fixed proportions is a mixture. When a chemical union occurs, this is when a compound is being formed. Hope this answer helps.</span>

4. D or G/I
5. A
Explanation:
This is about sort of concentrations:
1- Molarity
Moles of solute in 1 L of solution
(we can also say, mmoles of solute in 1 mL)
2- Molality
Moles of solute in 1kg of solvent
3. mass %
grams of solute in 100g of solution
4. mole fraction
moles of solute or solvent per moles of solution
5. ppm
mg of solute in 1kg of solution
(we can also say μg of solute in 1 g of solution, or mg solute in 1L of solution)
Answer:
<em>17500 calories</em> of chocolate bars are needed to eat to gain 5 pounds.
Explanation:
We can use ratios to calculate the answer using the information given in the question.
1 pound : 3500 grams
5 pounds : x grams
As it is given that the individual is burning no calories, we do not have to factor in any additional numbers.
<u><em>Method</em><em> </em><em>A</em><em>:</em></u>
To go from 1 in the first ratio to 5 in the second ratio, they multipled 1 by 5. Hence, to go from 3500 in the first ratio to x in the second ratio, we must multiply by 5.
x = 3500 × 5
x = 17500
<em><u>Method B</u>:</em>
To solve for the answer x, we can convert the ratios into fractions.
1 / 5 = 3500 / x
3500 / x = 1 / 5
To make x the subject, multiply the denominator of the left fraction with the numerator of the right fraction and place it on the left side. Then multiply the numerator of the left fraction with the denominator of the right fraction and place it on the right side.
x = 5 × 3500
x = 17500
