Revision Help

This post isn't an entry like I usually do. For those out there who also have their GCSEs ahead and can't contain information in they're head then you should know that your memory is more likely to store information that you see spontaneously... At least that's what this guy said at the assembly we had a while ago.

Electrolysis of Sodium Chloride and Copper:
At the anode you lose electrons; at the cathode you gain electrons.
OIL RIG - Oxidation Is Loss, Reduction Is Gain

acid + base = salt + water (+ carbon dioxide when the base is a CARBONATE)

A mutation is a change to the gene structure. If it happens in a sex cell, it can be passed onto the offspring.

That's science sorted :-)

In maths, any  number with indices of 0 equals 1 and nothing happens to any number with indices of 1 - it stays the same.
