<h2>~<u>Solution</u> :-</h2>
Here, we have been given the the amount of helium to be 52 amu.
Thus,
- Atomic mass of Helium is 4u = 2 protons + 2
- Neutrons = 1 atom.
- No. of atoms in 52u = $ \sf{\frac{52}{4}}$ = 13 atoms.
$ \red{\leadsto}$ Hence, the number of atoms will be <u>13 atoms</u>.
Answer:
True

Answer:
Rafflesia smell like roadkill others for only a few hours and while a few smaller species barely smell at all. And In short a parasitic life is heavily specialized biological requirements.
Explanation:
2, 4, 1
Explanation:
We have the following chemical reaction:
Ag₂O → Ag + O₂
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.
So the balanced chemical equation is:
2 Ag₂O → 4 Ag + O₂
