A student drew a diagram of the quantum model of an atom, as shown. Which of the following explains if the student's diagram is correct or incorrect?
The diagram is incorrect because electrons follow orbital rings around the nucleus
The diagram is incorrect because there is only a single type of particle at the center of the atom
The diagram is correct because electrons are present in a negatively charged cloud outside the nucleus
The diagram is correct because all electrons can be accommodated in two electron clouds around the nucleus

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
