Answer:
The answer to your question is: Nuclear fussion
Explanation:
In Chemistry there are 2 nuclear processes:
Nuclear fission: is the process in which the nucleus of a radiactive element splits into two smaller nucleus, or two elements woth lower atomic number.
Nuclear fussion, is a reaction is which to small nucleus combine to form a heavier element.
Answer: 106.905
Explanation: If there are only 2 isotopes, and 1 of them is 48.16%, the second must, by default, be (100 - 48.16%) = 51.84% The final, averaged, atomic mass is 107.868. This is made up of each isotope's atomic mass times the percentage of that isotope in the total sample. The weighted value of the known isotope (109) plus that of the unknown must come to the observed value of 107.868 amu. (107.868 - 52.45 = 55.42). Divide that by the % for that isotope (55.42/0.5184) = 106.90 amu for the second isotope.
<u>Atomic Mass</u> <u>% of Sample</u> <u>Weighted Value</u>
108.905 48.16% 52.45
X 51.84% <u>55.42</u>
107.87
X = (55.42/0.5184) = 106.90 amu
Answer:
7.53*10^23 atoms
Explanation:
Using stoichiometry convert moles of silver to moles of copper. Based on the equation, for every 2 moles of silver, 1 mole of copper is produced.
Then, convert moles to atoms with Avogadro's number.
Your answer should be 7.53*10^23 atoms.
Answer:
35 gm
Explanation:
What is mass of 0.6 mol C4H10
C4H10 has a molar nass of
(4X12) (10
X 1) = 48 + 10 8
so 1 mole of C4H10 is 58 gm
so 0.6 moles is
(0.6 X58) = 35 gm
