Question:

Can someone tell me how the formula for Aluminum Carbide comes out to Al4C3??? Please help?

I know that C has a -2 charge and Al has a +3 Charge, my answer came out to be AlC6 because I multiplied the charges togetherWould somebody be able to show me the steps to finding the correct formula please???

Answer:

elements are the simple pure form of a thinglike Zinc is only zinc (nothing else - so it is a elementCompounds are elements(plural) joined together exactly -( like water Hydrogen in direct proportion to the amount of oxygen hence it always stays the same , no matter what you do to it) A mixture is lots of things ( no proportions - just mixed up ) im no good at chem either but this is quite a basic starting point.
The only think I can think of that might be an element in every day life would be a light or something with Neon in it.but I'm not sure if that isn't bonded with somethingAs for compounds, that would be like NaCl which is Sodium Chloride, or Table SaltBy Mixture I'm assuming it's talking about a solution or something? Orange juice would be a mixture, koolaidIf these don't sound right, I might have something mixed up.
C does not have a -2 chargeBeing in column 4, it usually shares, but can gt a +4 or -4, depending on whether it gives or takes electronas a carbide, it is acting like a nonmetal taking electrons from aluminum(Al^+3) X 4 is +12 ( C^- 4 ) X 3 is -12
