<u>Answer: </u>The correct answer is Option D.
<u>Explanation:</u>
Unstable isotopes are defined as the isotopes which have excess of neutrons as compared to the stable form of the nucleus of an atom.
These isotopes attain stability by undergoing a spontaneous nuclear decay. The isotopes which are unstable have another name and are known as radioactive isotopes or radioisotopes.
These isotopes undergoes decay by 4 processes: Alpha decay, beta decay, gamma emission and positron decay.
Hence, the correct answer is option D.
2H₂ + O₂ → 2H₂O
mole ratio of O₂ : H₂O is 1 : 2
∴ if moles of O₂ = 16 mol
then moles of H₂O = (16 mol × 2)
= 32 mol
The buoyant force is the upward force or thrust...Simply, consider immersing your hand into a bucket of water. What happens to it? It raises (a little). The raising is due to the buoyant force. Basically it is the upward force/thrust that acts on any object immersed into a fluid. Hence why things float when out in water. Hope this helped!!
Answer:
dinitrogen pentoxide
Explanation:
Based on the research, dinitrogen pentoxide is a chemical compound containing only nitrogen and oxygen which is both nonmetal. When two nonmetals or two negatively charged atoms try to form bonds, they always form covalent bonds. Hence, Dinitrogen Pentoxide is not ionic - it is covalent.
