28.5g of iron shot is added to a graduated cylinder containing 45.50 ml of water. the water level rises to 49.10ml mark, from this info, calculate the density of iron.

Explain why scientists use shared characteristics to make cladograms.

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

Identify the lewis base in this balanced equation: fe3+ h2o fe(h2o)63+
