One coach of an Olympic rowing team makes his athletes warm up by doing 30 minutes of stretching and jogging in place before practicing each day. Another coach suggests that resting before practicing will result in better performance by her team. They decide to conduct an experiment to see which practice is correct. One team rests before practice, the other team warms up for thirty minutes, and they then record the time that it takes each team to row a specific distance. Identify the dependent variable in this experiment.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
