Hey there!:
Molar mass CuSO4*5H2O = 249.68 g/mol
Therefore:
1 mole CuSO4*5H2O ---------------- 249.68 g
3.2 moles --------------------------------- ?? ( mass of CuSO4*5H2O )
mass CuSO4*5H2O = 249.68 * 3.2
mass CuSO4*5H2O = 798.97 g
Hope that helps!
1. covalent bonds are strong
2. hydrogen bonds are weak
3. Ionic bonds are weak
The type of ion that the sodium atom form is a cation. The term cation is used to refer to ions which have positive charges. The valence electron of sodium is one and in order to obtain the octet, it will donate that electron to some other atoms, making its charge positive.
The kind of reaction that is likely to be observed is a single displacement reaction where the metal displaces the H+ ion from the acid. The general chemical reaction would be written as 2M + 2HX = 2MX + H2 where M represents a metal and HX is the acid.
Answer:
C: metals donate electrons to non metals
