Need some help with Chemistry?
Q. 1. Why are AlCl3 (aluminum III Chloride), CuO (Copper I Oxide), and CCl4 (Carbon IV Chloride) incorrect formula and naming relations? 2. Why is HGOH (Mercury II Hydroxide) an incorrect formula and TiO2 (Titanium IV Oxide), CuBr (Copper I Bromide), and Fe2(CO3)3 (Iron III Carbonate) correct formulas?

A. "Na" is sodium and the "N" there represents the ion of Nitrogen therefore Na3N is Sodium nitride you know that it is an ionic compound since it is between a metal and a non-metal. simple anions (negative ions) are formed by changing the root of the element to -ide. Example, nitrogen -> nitride, oxygen ->oxide, chlorine -> chloride Therefore, Na3N is sodium nitride and Ca3P2 is calcium phosphide to name complex ions you simply have to learn the names of the common ones (HSO4 is hydrogensulphate or bisulphate, NH4 is the ammonium ion) therefore NH4HSO4 is ammonium hydrogensulphate the C2H3O2 - ion is the ethanoate/acetate root from an organic acid (again you just have to learn these) therefore the compound is beryllium ethanoate (or… [cont.]

Al2(SO3)3 To write the formula for ionic compunds, simply find the charge of the ions within the compound. Metal ions have a positive charge, and non-metal ions have a negative charge. Then, look at the ions and ask yourself, how many of each ion do I need for the charges to cancel out? For example, calcium chloride contains Ca2+ ions and Cl- ions. So you would need 1 Ca2+ ion to cancel out 2Cl- ions. To find the charges of ions, look at a periodic table. Metals gain electrons when they react, and non-metals lose electrons when they react. How many electrons… [cont.]
