Suggest three properties which magnesium chloride has because it is an ionic compound
High melting point; strong; dissolvable
1 of 5
Explain fully why sodium chloride has a high melting point
It has strong ionic bonds which require lots of energy to overcome
2 of 5
Explain why magnesium has a charge of 2+
It has two electrons on its outer shell, therefore it loses two electrons
3 of 5
Explain why graphite can conduct electricity
In graphite, each of the carbon atoms has one delocalised electron. These move between layers and carry charge.

Why is graphite used as a lubricant?
Graphite is used as a lubricant because of its weak intermolecular forces. These forces enables the layers to slide over each other causing graphite to have soft and slippery surfaces
