No. Roman numerals are only for cations that aren't in either group 1 or 2. For this, you would say Chlorine Tetroxide.
ClO4 is polar.
ClO3 has the smaller bond angle than ClO4
Tetrahedral
Because ClO3- has a lone pair on the central Cl atom, which pushes harder away than a bond would.
Perchlorate ion (ClO4-) is colorless.
Cu(ClO4)2 dissociates into Cu2+ ions and 2 ClO4- ions in solution. This results in the breakdown of the copper perchlorate compound into its constituent ions when dissolved in water. The balanced equation for the dissociation of Cu(ClO4)2 is: Cu(ClO4)2 -> Cu2+ + 2 ClO4-.
The formula for magnesium perchlorate is Mg(ClO4)2.
The chemical symbol for perchlorate is ClO4-.
The formula for the perchlorate ion is ClO4-. It consists of one chlorine atom bonded to four oxygen atoms.
ClO4 is polar.
In ClO4-, the oxidation number of Cl is +7, and the oxidation number of each O is -2.
The symbol for the oxyanion perchlorate ion is ClO4-.
baking soda.
ClO3 has the smaller bond angle than ClO4
The formula for mercurous perchlorate is Hg2(ClO4)2.
The answer is Cd(ClO4)2 The charge of cadmium(II) is 2+, and the charge of ClO4 is 1-. So to even the charges we must have two of the ClO4.
