Why does Sodium Chloride have high melting point?

Sodium Chloride has a high melting point, as it has a giant ionic lattice hence has strong electrostatic forces of attraction between oppositely charged ions, which requires lots of energy to overcome the fo...

Iron is found in the Earth as iron oxide (Fe2O3). Iron oxide is reduced to produce iron. Balance the equation for the reaction. ___Fe2O3 + ___C → ___Fe + ___ CO2

Balancing means that you have the same number of atom on one side as you do on the other. The reason for balancing is because atoms are not lost or created during a reaction. Keep in mind that when you balan...

CuCl2 + 2NaOH --> Cu(OH)2 + 2NaCl. 100kg of CuCl2 reacts with excess Sodium Hydroxide. 50kg of Sodium Chloride is produced. Calculate the theoretical yield of Sodium Chloride, and hence the percentage yield of Iron in this reaction.

Theoretical Yield of NaCl = 86.7kg (3sf)Percentage Yield of Iron = 57.7% (3sf)
