Answer to Question #151016 in General Chemistry for Lauren Barad

Question

1. Calcium is an ion that is needed by organic systems for proper bone density and cellular metabolism. However, solid calcium has a great deal of energy in its elemental form, therefore it is commonly broken down into an ion. Given your knowledge of the periodic table what is the oxidation state of the ion of calcium?

2. Carbon, another element key to organic systems, is commonly ingested as the ion carbonate. write the formula for this ion.

3. Calcium supplements are commonly ingested in the form of a calcium carbonate tablet, if a patient cannot swallow pills calcium carbonate is extremely soluble and can easily be dissolved in water. Show the dissociation equation of calcium carbonate.

a. In the box below, draw a particle representation diagram that includes four water molecules with proper orientation around the Ca ion.

4. Solid calcium carbonate and water do not conduct electricity. However, calcium carbonate in water does. On a chemical level, explain this.
