2na + mgcl2 -> 2nacl + mg. the problem is to find how many grams of sodium chloride is formed from 12.5g of sodium.

12.5g*(1 mole/23 g)=0.54 mol

0.54 mol*(23 g+35.5 g/1 mol)=32 g

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
