Solutions by Chapter
The correct name is potassium hypochlorite. Use a Roman numeral to specify the charge of the Fe ion. The correct name is iron II chloride. The correct name is iron II oxide. Use a Roman numeral to specify the charge of the Ti ion. The correct name is titanium IV chloride. Compare this to sodium oxide in part l.
The correct name is sodium peroxide.
At the end of the name, we add hexahydrate for the six waters of hydration. The correct name is iron III chloride hexahydrate. When writing formulas of ionic compounds, the subscript of the cation is numerically equal to the charge of the anion, and the subscript of the anion is numerically equal to the charge on the cation.
If the charges of the cation and anion are numerically equal, then no subscripts are necessary. Charges of common cations and anions are listed in Table 2. Keep in mind that Roman numerals specify the charge of the cation not the number of metal atoms. Remember that a Roman numeral is not needed for some metal cations, because the charge is known.
When writing formulas of oxoacids, you must know the names and formulas of polyatomic anions see Table 2. Since, the charges are numerically equal, no subscripts are necessary in the formula.
The correct formula is CuCN. Since the charges on the cation and anion are numerically different, the subscript of the cation is numerically equal to the charge on the anion, and the subscript of the anion is numerically equal to the charge on the cation.

The correct formula is Sr ClO2 2. The correct formula is HClO4 aq. Remember that aq means that the substance is dissolved in water.
The correct formula is HI aq. The correct formula is PbCO3. The correct formula is SnF2. The Greek prefixes tell you the number of each type of atom in the molecule. The correct formula is P4S Oxide has a -2 charge.
The correct formula is HgO. The correct formula is Hg2I2. We add 6H2O at the end of the formula for the six waters of hydration. The element that contains 30 protons is zinc, Zn. The two electrically neutral carbon isotopes should have nearly identical chemical properties; that is c. A, F, G. One cannot be sure.A hypothesis is Answer a tentative explanation for a set of observations that can be tested by further experimentation.
We have solutions for your book! Rutherford also proposed that the nucleus was a dense central core with most of the mass of the atom concentrated in it. Fundamental particles are particles that were once thought to be the indivisible components of all matter. The correct formula is P4S Why download extra books when you can get all the homework help you need in one place?
Above that are the mantle and crust. Editorial Staff October 17, at An empirical formula shows the elements present and the simplest whole number ratio of the atoms but not necessarily the actual number of atoms in a given molecule.
