Answer:
Explanation:
Metallocenes are cyclic organometallic compounds with a double pentadienyl structure consisting of a metal atom in between the two structures. In ferrocene, Fe is the metal in between the two pentadienyl structures.
Nitration reaction is the reaction of nitric acid in the presence of sulphuric acid. When metallocenes, (e.g. ferrocene) are being treated with this stong oxidizing agent (nitric acid), oxidation of organometallic compound takes place. When this oxidation occurs, it oxidizes the oxidation state of the Fe metal from +2 to +3 in ferrocene, and it becomes unstable. Then, as a result, the whole metallocene structure gets destroyed.
<u>Answer:</u> The number of electrons in given amount of silver are
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass.
The equation used is:
......(1)
We are given:
Mass of silver = 7.0 g
Molar mass of silver = 107.87 g/mol
Putting values in equation 1:
According to the mole concept:
1 mole of a compound contains number of particles.
Number of electrons per atom of silver = 47
So, 0.065 moles of silver will contain = number of electrons
Hence, the number of electrons in given amount of silver are
There are 0.23 moles in 34.1g of AgCl, I believe.

Answer:
56
Explanation:
1 mole of gas at STP occupies 22.4 L of the gas
2.5 mole of the gas at STP occupies 22.4×2.5 L of the gas
so 2.5 mole of the gas at STP occupies 56 L of the gas .
