It is true that metallic bonds are responsible for many properties of metals such as conductivity.
Metallic bond is a type of chemical bond.
Metallic bond is formed between electrons and positively charged metal ions.
Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.
Most metals (for example sodium, calcium, iron, silver) have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.
Metallic bond increace electrical and thermal conductivity.

To figure this out, you need to figure out how many molecules of mgso4 you have.
If you have 1.04 moles of MgSO4, you have that many moles times avogadro's number (6.022*10^23 molecules/mole).
1.04 moles MgSO4 * (6.022*10^23 molecules MgSO4)/1 mole MgSO4 =
6.263 *10^23 molecules MgSO4
Next, there are 4 oxygen atoms per molecule of MgSO4, so we multiply the number of molecules of MgSO4 by 4 to get the number of oxygen atoms.
6.263 *10^23 molecules MgSO4 * (4 oxygen atoms/1 MgSO4 molecule) = 2.51 * 10^24 oxygen atoms in 1.04 moles of MgSO4
2 H2O2 - 2 H2O+O2 - Balanced Equation and its a decomposition reaction.
