Chemical Equations
|
|
|
HI i'm a 15 yr old student of Chemistry. I was just wondering if there
are any easy ways to remember chemical equations- like any sort of
general stuff(like combustion reactions which yield mostly water and
carbon dioxide) and also a way to commit to memory the various
temperature conditions of the reaction. I know i'm trying to look 4 an
easy way out of memorizing the equations but does anyone know any
techniques? |

The first thing a beginning chemistry student like you needs to know
are the rules for writing and identifying stable compounds. Are you
already familiar with common oxidation states of elements, and are
you
able to write formulas and names for inorganic compounds?
Next is learning to identify a few general types of reactions, which
seems to be your question. One website which describes some basic
reaction types, with examples, is the following:

and this

I'm not sure what you're asking in the second part of the question,
about temperature conditions. Are you talking about the
thermodynamics
of reactions? Entire books have been written on that topic. What
specifically are you trying to memorize or understand?

Nicely put ... For inorganic reactions ... I think ... does this metal
want to reduce or oxidize ... what would be the lower energy state
....anything precipitate .. ??
For organic ... does that carbon want to be a carbonium ion or a
carbanion ... or is it happy the way it is ... ??? Funny how those
simplistic thoughts and others like it can get a student through a
tough exam ... thinking like a chemist rather than memorizing like a
biologist ... |
