I understand Ionic, Molecular, and Acidic Nomenclature. I just don't get how to do chemical reactions.?
Can someone please help me out w/ Combination, Combustion, Decomposition, Single-Replacement, and Double-Replacement reactions. I heard you have to know some nomenclature to do it. I was taught how to do some reactions in class but I plain just don't get it. If you could possibly give an example of each and show me the steps to balance the equation and just get the right product that would be the best. I appreciate anyone who tries to attempt this question. Thanks a lot. Also...I forget which one is the anion and which one is the cation. Which one has the negative charge and which ones has the positive charge?
Cation is positive (see the "t" in ca"t"ion? it stands for positive. That means the anion is negative. A combination is A + B-> C. (Example: Ca which has a +2 charge plus Cl which has a -1 charge reacts Ca+2 + Cl-1 -> CaCl2 (crisscross the charges to get the subscripts.) Combustion ALWAYS yields CO2 + H20. Decomposition breaks a molrcule up. AB-> A + B (Example: NaCl -> Na + Cl be sure to balance the equations.) In a single replacement a "couple" we'll call AB is having "problems". While out at a restaurant single person C walks by and someone in the couple jumps ship and leaves with C. The equation is AB + C -> CB + A . Check your charges on C and B and crisscross them, then balance the equation. In a double replace ment AB are out at the restaurant and couple CD come in. They too are having "trouble" Now everybody chages partners. Be sure a cation pairs with an anion in each case. Check charges and crisscross, then balance. AB + CD -> AD + CB
