The rule of three is a way to solve problems of proportionality between three known values and one unknown. <u>This is an operation of finding the fourth term of a proportion knowing the other three</u>.
We can use the rule of three to solve this problem in this way,
500 mL → 6 grams
40 mL → x
This is the same as saying: if in 500 mL there should be 6 grams of agarose powder then in 40 mL how many grams should there be?
So,
→ x = 0.48 g = 480 mg
Then, you need to dissolved 480 mg of agarose powder in 40 mL of water to meet the recipe.
Answer:
The correct option is: C. form stable hydrogen-bonded dimers
Explanation:
Boiling point is the temperature at which a particular substance changes from liquid state to vapor state.
The boiling point of a chemical substance depends upon the intermolecular forces present between the molecules.
Carboxylic acids are the organic molecules containing carboxyl functional group (COOH). <u><em>They tend to have greater boiling point than alcohols, ketones, or aldehydes.</em></u>
<u>This is because only carboxylic acids are capable of forming </u><em><u>dimers that are stabilized by hydrogen bonding.</u></em>

Answer:
<h3>a. noble gases</h3>
Explanation:
Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.
