Concept explainers
Energy bars contain ionic compounds that serve as a source of the trace elements that the body needs each day for proper cellular function. Answer the following questions about some of the ingredients in one commercial product.
a. Write the formulas for magnesium oxide and potassium iodide.
b. The ingredient
c. Give two different names for the ingredient
d. Sodium selenite is one ingredient. Selenite is a poh atomic anion that contains a selenium atom in place of the sulfur atom in sulfite. With this in mind, suggest a formula for sodium selenite.
e. Another ingredient is listed as chromium chloride. What is wrong with this name?
