Hi, for my AP Chemistry class we do reaction prediction problems. We get sheets of them, ones that say things like A limited amount of liquid bromine is added to an excess of benzene or Solid zinc slufide is heated in an excess of oxygen, or Dilute acetic acid solution is added to solid magnesium carbonateOur teacher hasn‘t really taught us anything, it‘s pretty much read and learn the concepts on your own. I‘m having trouble with turning names into compounds? Like how do I know copper (II) sulfate is Cu2+(sulfate). Like I‘m having trouble taking the written out name of the substances and putting them into chemical notation O2, CO2H2O, etc. also how do I know the charges and how do I balance them? I realize some are polyatomic ions and must be memorized, but yeah I just need a quick general breakdown of doing these reaction prediction problems!Thanks
Do you mean what has highest R-factor per inch?
Barium nitrate is Ba (NO3)2. i might confirm that if this grew to become right into a typo on the instructor's section, he might in no way comprehend if it grew to become into or no longer. in accordance to a cutting-edge article (see references) ninety 3% of scholars interior the 5th via 8th grades are being taught technology via a instructor without the two a technology degree or technology certification. And 70% of those scholars are being taught math via instructors without the two a math degree or math certification.) CuAt2 is the attempt of an incompetent instructor to invent a Gp II halide. thinking the tendency of the halide components to develop into extra metallic, it might additionally be a metallic alloy.if it existed.
Hello Zach The bottom line here is that you need to learn some common oxidation numbers. And if you see names like copper II sulfate, you automatically know that the copper is using a plus 2 charge, and you have memorized the charge on the sulfate ion and its formula as SO4 so you write CuSO4 and your are done Say you need to write the formula for Barium Phosphide. first of all if a name ends in ide you automatically know that this compound contains only two elements, Ba and P now Ba is in group 2A and has 2 electrons in its outer energy level which it will donate to the P and take on a charge of plus 2. Now look up the possible valences or oxidation numbers for Phosphorus and find a negative 3. The other charges are all positive and a positive ion does not combine with another positive ion like Ba so you know that Ba will have a charge of plus 2 and the P will be a minus 3. 2 and 3 will go into what small number? Six. Ba++ goes into six three times, so you need Ba3 and P^-3 goes into six 2 times so you need P2 and the formula is Ba3P2. so start learning common oxidation numbers. All elements in group iA are plus one all in group IIA are plus 2 all in group 6B, ( oxygen family) , same as group l6 on some P tables are a minus 2 except for Po all in group l7 or 7B, the halogens are a minus one. That will get you started. A good web site for you is called Chem Team Check it out
