Answer:
6.9 hours
Explanation:
In order to solve this problem we'll<u> convert 837 km to miles</u> (another option would be to convert 75 mi/hr to km/hr). To make said conversion we'll use the given <em>conversion factor</em>:
- 837 km * = 519.88 mi
Finally we <u>calculate the time required to travel said distance</u> at a constant speed of 75 mi/hr:
- 519.88 mi ÷ 75 mi/hr = 6.9 hr
Answer:
Option D
Explanation:
Molarity (M) of any solution is equal to the number of moles (n)of solute in it divided by total volume of solution (V)
Mathematically, it can be represented as
Substituting the given values, we get-
Hence, option D is correct
Antioxidants are the substance that prevent oxidation process in a cell, oxidation produce free radical, and free radicals harm the cell. The oxidation number is the count of electrons present in an atom.
<h3>What is ascorbic acid?</h3>
Ascorbic acid (vitamin C) is a water-soluble vitamin that is present in the citrus fruits and vegetables.
Ascorbic acid act as an antioxidant and prevent the production of free radicals in a cell.
Thus, Antioxidants are the substance that prevent oxidation process in a cell, oxidation produce free radical, and free radicals harm the cell. The oxidation number is the count of electrons present in an atom.

Answer:
Acid rain
Explanation:
The independent variable in the hypothesis statement is the acid rain. An independent variable is usually the cause in an experiment.
This variable give rises to the effects observed as the dependent variable.
In the presence of the acid rain, the fish population will increase.
The dependent variable is the fish population or number of fishes.
The independent variable is the acid rain as it is the cause of the effect observed on the fish population.
