Magnesium chloride is an ionic compound and has a high melting point. Explain why magnesium chloride has a high melting point?

Magnesium atoms lose two electrons from its outer shell, thus form positvely charged ions with a charge of 2+. These 2 electrons are transferred to and gained by a diatomic molecule of chlorine atoms - ea...

What is meant by the term salt? And how would you confirm if the salt had chloride ions in?

Part 1: "A salt is is when the Hion in an acid is replaced with a cation (e.g. a metal)" 

Part 2: You would use the silver nitrate test for halide ions. You add dilute nitri...

Using the VSEPR theory, predict the shape of CCl4 and its approximate bond angles.

  1. Draw out the lewis structure of CCl4 by counting the number of valence electrons on each atom. C=4, Cl=7 therefore total valence electrons is 4+(7x4)=32 and total valence electron pairs is 16. 2. De...
