1. Determine the total pressure of a gas mixture that contains oxygen at a pressure of 150 mmHg, nitrogen at 350.mmHg pressure, and helium at a pressure of 200 mmHg.

what does the table look like

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

consider the reaction below.
