So, i need help with my chemistry. I do need help on how to balance equations. please give me the best steps on how to. thanks. for example: Fe+S8 --> Fe2S3 (a formation equation) and CuO --> Cu + O2 ( a Decomposition equation) Cu + AgNO3 --> Cu(NO3)2 (a single replacement equation) and: KOH + H2So4 --> H2O + K2SO4 (a double replacement equation) Also i need some help with Ions in chemical formulas. I am supposed to write a correct formula for the compound formed by each of the following pairs of ions . Examples : Na1+ F1- , K1+ S2-, Ni2+ SO4.2-, Al3+ O2-, and, Ca2+ ClO3.1-. And onneee more thing. for each compound i need to write .... The symbols of the ions in the compound&the number of each ion in one molecule of that compound. For examples: Cal2, Na2CO3, Ga(ClO3)3, CuF2, & (NH4)3PO4. Also on how to write the name of compounds : Na2S, Al2O3, NaCl, Rbl, & ZnBr2. By the way, you do not need to answer all of my examples i gave to you, i just need a couple examples and how to do each formula. thanks. and whoever gives the best answer, i will answer your question on your personal yahoo answers page . =]...
