<u>Question</u>:
Which value is being measured in the columns labeled "Fraction remaining” and "Percentage remaining”?
-
years of decay
- quantity of energy
- number of stable atoms
- amount of material that has not decayed
<u>Answer</u>:
"Amount of material that has not decayed" being measured in the columns labelled "Fraction remaining” and "Percentage remaining”
<u>Explanation</u>:
The table shown below having explains about the half life , the amount of sample in both fraction and percentage. The first column named half life elapsed tells us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.
The fraction remaining column gives the amount of sample that is left behind after the half life particular number of half life has completed. similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over
of the sample remained. In percentage it is 6.25%

Answer:
See explanation.
Explanation:
Hello.
In this case we can for instance take into account the following mixtures:
- Orange juice.
- Tea.
- A soda.
- Salty water
- Coffee.
Thus, since the orange juice is a suspension as long as it contains different sizes of orange pulp particles that cannot be dissolved mostly because of its organic nature.
Tea can be a solution when we place a tea bag in a cup with warm water since just soluble components of tea are successfully dissolved in the water. Moreover, homemade tea based on some plants are fruits may behave as a suspension due to the oraginic particles that are not dissolved in the water yet suspended.
A soda is a solution of some water-soluble compounds, gaseous soluble carbon dioxide and water which are homogeneously distributed in the solution.
Salty water can be a solution if you put some salt in warm or just cold water and wait until it dissolves completely.
Coffee can be also a solution or suspension depending on how it is made, which type of coffee is used and the amount of coffee added to the hot water.
Best regards.
Answer is A. I kid chemistry a while back but I am pretty certain it is A.
