Give a claim that can support "Newton's Laws of Motion can help us understand the physics involved in real world events, such as NASCAR races and crashes

Significant figures are digits read directly from the measuring instrument plus one more digit, which is __ by the observer.

When electrolyzing copper (ll) chloride, what reaction takes place at the anode? what reaction takes place at the cathode?

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
