Answer:
I don't know spanish, ask someone else
The correct answer is B. Fusion only happens between small atoms. Thus, hydrogen-2 and hydrogen-3 can undergo fusion. Fusion reaction happens when two or more nuclei combine or collide to form an element with a higher atomic number. In this process, some of the matter of the fusing nuclei is converted to energy.

<u>Answer:</u> The percentage abundance of and isotopes are 75.77% and 24.23% respectively
<u>Explanation:</u>
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
.....(1)
Let the fractional abundance of isotope be 'x'. So, fractional abundance of isotope will be '1 - x'
- <u>For isotope:</u>
Mass of isotope = 62.9396 amu
Fractional abundance of isotope = x
- <u>For isotope:</u>
Mass of isotope = 64.9278 amu
Fractional abundance of isotope = 1 - x
- Average atomic mass of copper = 63.546 amu
Putting values in equation 1, we get:
Percentage abundance of isotope =
Percentage abundance of isotope =
Hence, the percentage abundance of and isotopes are 69.50% and 30.50% respectively.
Answer:
2.5 L will be the volume of HNO₃
Explanation:
To find out the total volume of nitric acid in liters we begin from molarity.
HNO₃ solution is 0.10 M
This means that 0.10 moles are contained in 1L of solution.
As we used 0.25 moles of nitric, let's determine the volume by a rule of three:
0.10 moles of nitric acid are contained in 1L of solution
0.25 moles of nitric acid will be contained in (0.25 . 1) / 0.1 = 2.5 L
