Explain why ionic compounds (e.g. NaCl) are soluble, and why they conduct electricity in this state.

Ionic compounds have a 'giant' ionic lattice structure. 'Giant' just essentially means that a basic unit is being repeated. In the case of NaCl, the ionic lattice would consist of the ions Na+ and Cl-. Wa...

Carbon dioxide is a gas at room temperature while silicon dioxide is a solid at room temperature with a melting point of 1770°C. Explain this by comparing their particles and those forces between these particles.

Although C and Si are both group 4 elements, C is much smaller than Si and can form double bonds with two oxygen atoms whereas Si is larger and so forms single bonds with four oxygen atoms. This means th...

Why is the boiling point of water significantly greater than that of other group 6 (16) hydrides?

Water exhibits hydrogen bonding between neighbouring molecules, where other group 6 hydrides are held together by much weaker (ca. 10 x) Van Der Waal's forces of attraction. Waters hydrogen bondong abilit...

How does a mass spectrometer work?

Mass spec is used alongside many analytical techniques, and provides information of the structural formula of a molecule such as proteins. Initially the sample is vapourised and then ionised by bombarding...

How do i know what the major and minor products of the reaction between Hydrogen Bromide and Propene would be?

We would use something called Markovniov's rule. Essentially, the H+ ion (or proton) that is attracted to the electron dense double bond of the alkene, is added to the carbon that has the most Hydrogen at...
