CaCl2 ^actually this answer is wrong. chlorate is ClO3 with a charge of 1- . Calcium has a charge of 2+. Use the criss-cross rule and you get Ca(ClO3)2. Therefor the right answer is Ca(ClO3)2
Ca(ClO3)2
Calcium chlorate is an ionic compound.
Ca(ClO3)2
9
The formula is Ca(ClO3)2, so the total number of atoms in the compound is 9.
In Ca(ClO3)2 there are one calcium atom, two chlorine atom and six oxygen atom. So total of nine atoms
Calcium chlorate: Ca(ClO3)2
Assuming that the compound is the one that should have been written as Ca(ClO3)2, the answer can be determined by counting in a properly interpreted formula: one Ca, two Cl, and six O for a total of nine.
Ca is calcium, one atom.
Calcium chlorate has the formula Ca(ClO3)2. Therefore, there are two chlorine atoms in each formula unit.
CaCl2 ^actually this answer is wrong. chlorate is ClO3 with a charge of 1- . Calcium has a charge of 2+. Use the criss-cross rule and you get Ca(ClO3)2. Therefor the right answer is Ca(ClO3)2
