Calculate the theoretical yield and the percentage yield of nitrogen oxide if 49.2 grams of nitrogen dioxide yield 8.90 grams of nitrogen oxide in the reaction of nitrogen dioxide and water to form nitric acid and nitrogen oxide.
calculate the molarity of a solution of glycerol made by dissolving 69.000 ml glycerol at 15 degrees c in enough water
The solubility of oxygen gas in water at 25 °C and 1.0 atm pressure of oxygen is 0.041 g/L The solubility of oxygen in water at 3.0 atm and 25 °C is __________ g/L.
What is an electron? An electron in terms of a subatomic particle in chemistry.
Volcanic eruptions can be a significant source of air pollution. The Kilauea volcano in Hawaii emits 200-300 t of SO2 per day. If this gas is emitted at 800°C and 1.0 atm, what volume of gas is emitted?
Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP
