Co(NO3)2 becomes CO(NO3)2!

One of the chemical equation tool's most useful features is its ability to capitalise elements for you.  This can save you large amounts of time when entering equations. Some elements will cause the chemical equation tool problems.  For example, if you type co, the chemical equation tool will ALWAYS interpret that as carbon/oxygen and change it to CO.  This, obviously, will almost always be a correct interpretation.  If you really want cobalt, Co, enter it correctly capitalised as Co and the chemical equation tool will leave it alone.  In other words, if your compound contains ONLY lower case letters, the chemical equation tool will capitalise it for you taking its best guess.  If the chemical equation tool finds any upper case letters in your compound it will leave it as you wrote it.  That way you can always get the required result.

This issue can also affect Si compounds.
