Find a calcium atom and an oxygen atom. These two atoms will bond to form Calcium Oxide, CaO. CaO is a chemical formula. 1. Based on the puzzle pieces, why does it look like Ca and O should bond together? 2. If we want to replace calcium, what elements could we use? Mg, Be 3. Are those elements in the same family or period? Family 4. What would be those formulas? 5. If we wanted to use replace oxygen, what element could we use? 6. What would be those chemical formulas?

The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 1.500 g • She put some solid sodium thiosulfate into the graduated cylinder and weighed it. With the sodium thiosulfate added, the cylinder weighed 96.6 g. She added water to the graduated cylinder and dissolved the sodium thiosulfate completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 97.7 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant…
