Se calienta una muestra de piedra caliza y otros minerales, y la primera se descompone para dar oxido de calcio y dioxido de carbono. cuantos gramos de oxido de calcio se produce con 7 moles de carbonato de calcio si tiene el 75% de pureza?

If 1.8 l of water is added to 2.5l of a 7.0 m koh solution, what is the molarity of the new solution

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
