A student uses heat to decompose 25.0 g of Naclog and collects the oxygen over water. The temperature of the water is 35°C and the barometric pressure is 747 mmHg. Assuming 100% yield, what is the volume of Oxygen gas collected?
(Show calculation for moles of oxygen, pressure of oxygen, equation for determining volume, and the answer)

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
