Calcium chlorate has the formula Ca(ClO3)2. Which best describes the structure of calcium chlorate? One molecule of calcium chlorate contains nine atoms. Calcium chlorate is an element that contains three atoms. It takes nine different elements to make one molecule of calcium chlorate. Calcium chlorate contains two Ca groups.

The formula Ca(ClO3)2 breaks down to: 1 calcium atom, 2 chlorine atoms, and 6 oxygen atoms. Therefore:

One molecule of calcium chlorate contains 9 atoms [correct]

Calcium chlorate is not an element, nor does the molecule contain only 3 atoms [incorrect]

It does not take 9 different elements - just the three elements we listed [incorrect]

Calcium chloride only contains one Ca group [incorrect]

The formula Ca(ClO3)2 breaks down to 1 calcium atom, 2 chlorine atoms, and 6 oxygen atoms. One molecule of calcium chlorate contains 9 atoms. Thus the correct option is A.

How calcium chlorate is formed?

Calcium chlorate is formed by passing chlorine gas through a hot suspension of calcium hydroxide in water, producing calcium hypochlorite, which disproportionate when heated with excess chlorine to give calcium chlorate and calcium chloride.

6 Ca(OH)2 + 6 Cl2 → Ca(ClO3)2 + 5 CaCl2 + 6 H2O

This is also the first step of the Liebig process for the manufacture of potassium chlorate. Liebig's method is used for the estimation of carbon and hydrogen.
