Answer:
The value of Keq is 4e-9. See the solution below
Explanation:
We need to balanced rhe equation and use the formula of the Keq
Answer:yes they have the same mass.
2,000 times as massive as an electron.
The nucleus
electrons make the greatest contribution to the chemical properties of the atom.
Explanation:
The average atomic mass of the element is 204.40 amu
<h3>Average atomic mass and isotopic mass</h3>
- The average atomic mass of an element is the average mass of the atom of that element calculated from the isotopic masses of the atoms of that element and their percentage abundances
- Isotopic mass is the mass of each isotope of that element
<h3>Calculation of average atomic mass</h3>
Average atomic mass = sum of isotopic mass * abundance of each isotope
Average atomic mass = 202.99 * 29.524% + 70.476% * 204.99 amu.
Average atomic mass = 204.40 amu
Therefore, the average atomic mass of the element is 204.40 amu
