Agraduated cylinder contains 20.0 ml of water. an irregularly shaped object is placed in the cylinder, and the water level rises to the 31.2-ml mark. if the object has a mass of 7.42 g, what is its density?

What is the equilibrium constant of aa+bb=cc+dd

Identify two types of chemical bonding in the source of dietary potassium

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
