Part (a): The masses From the periodic table: molar mass of copper = 63.5 grams This means that: mass of 2..06 moles = 2.06 * 63.5 = 130.81 grams comparing this mass with the 222 grams of silver, we will find that the mass of silver is greater.
Part (b): The atoms: number of moles = mass / molar mass number of moles of silver = 222 / 107.8 = 2.059 moles each mole contains Avogadro's number of atoms. Since number of moles of copper is slightly larger than nuber of moles of silver, this means that the number of atoms in the copper sample would be more.
there is a transfer of electrons from one material to the other material. This causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer).
The correct option in here is the first one: <span>pentane-1,5-diamine. This is also known as cadaverine. This is a common compund that produces that unpleasant odor from the fish. </span>
