Answer:24.31
Explanation:Contribution made by isotope of mass 23.99= 23.99×78.99=1894.97
Contribution made by isotope of mass 24.99=24.99×10.00=249.9
Contribution made by isotope of mass 25.98=25.98×11.01=286.04
Total contribution=1894.97+249.9+286.04=2430.91
Average mass=2430.91÷100
=24.31
Answer:
After Eris was discovered, they had to decide whether Eris was a planet or not. If they decided it wasn't a planet, they had to also decide whether Pluto should be counted as a planet since Eris and Pluto were quite similar. They were the same size, and they were both part of the Kuiper Belt.
Explanation:
Answer: New concentration of 
is 0.23 M.
Explanation:
The given data is as follows.
Moles of = 0.06 mol
Moles of 
= 0.08 mol
Therefore, moles of 
added are as follows.
Moles of = 
= 0.003125 mol
Now, new moles of = 0.06 + 0.003125
= 0.063125
Therefore, new concentration of will be calculated as follows.
Concentration = 
= 0.23 M
Thus, we can conclude that new concentration of is 0.23 M.
H2 + O = H2O
Hydrogen is a diatomic molecule and reacts with oxygen to create Water or H2O
