The correct answer is option B. A molecule is two or more atoms (same or different) bound together. It is the smallest particle in a chemical element or compound. Molecules are held together by chemical bonds. These bonds are formed by the sharing or transfer of electrons between atoms.
Barium, it's an earthy alkaline metal it's atomic number is 56
The temperature will become greater because of the increased velocity of the molecules.
Answer:
They both alter the pH of a solution.
Explanation:
If a strong acid is added, the pH of a solution will lower. This is because more hydrogens/hydroniums are increasing in the solution. If a strong base is added, the pH will increase. This is because hydrogens/hydroniums are decreasing in the solution.
<u>Answer:</u>
5
<u>Explanation:</u>
We know that,
number of count of cardinals = 75; and
measured area = 15 square kilometers.
To find the population density of the cardinals in an area of 15 square kilometers, we need to divide the number of cardinals by the given unit area:
Population density of cardinals = 75 / 15 = 5
Therefore, the population density of cardinals in an area measuring 15 square kilometers is 5.
