Cans aren't entirely made of tin because of rusting. When scratched(which happens quite frequently to cans) the tin is in more danger of rusting. This is why the cans are coated in a layer of tin rather than the whole can is made of it.
An electron is a negatively charged subatomic particle, whereas a proton is positively charged, and a neutron has no charge.
Cations are formed by losing electrons in the valence shell of atoms. There are more protons than electron ions making the atom more positive.

Explanation:
Hello there!
In this case, according to the described chemical reaction, it is possible to compute the theoretical mass of silver as mass via the 1:2 mole ratio of copper to silver and their atomic mass in the periodic table, in order to perform the following stoichiometric setup:
Next, given the actual yield of 120 g, we compute the percent yield via:
Regards!
Answer:
To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol).
