The three chemicals listed below are all very weak acids because they all have a difficult time losing a hydrogen ion, H + . Upon losing this hydrogen ion, the central atom of each of these molecules takes on a negative charge. Holding onto this negative charge isn’t easy, especially when there are positively charged hydrogen ions, H + , floating about ready to combine with this negative charge. Review the concept of electronegativity in Section 15.6, and rank the acidity of these molecules in order from strongest to weakest: (a) ammonia, NH 3 ; (b) water, H 2 O; (c) methane, CH 4 .

Race car driver is cruising down the street at a constant speed of 28.9 m/s (~65 mph; he has a “lead” foot) when the traffic light in front of him turns red. a) If the driver’s reaction time is 160 ms, how far does he and his car travel down the road from the instant he sees the light change to the instant he begins to slow down? b) If the driver’s combined reaction and movement time is 750 ms, how far do he and his car travel down the road from the instant he sees the light change to the instant he slams on her brakes and car begins to slow down? Please answer parts a-B. Show all work. For each question draw a diagram to show the vector/s. Show all the step and provide units in the answers. Provide answer to 2 decimal places. DONT FORGET TO DRAW VECTORS! ONLY USE BASIC FORMULAS TAUGHT IN PHYSICS. distance = speed * time.

Please answer parts a-c. Show all work. For each question draw a diagram to show the vector/s. Show all the step and provide units in the answers. Provide answer to 2 decimal places unless stated otherwise.…
How is it that part a is connected to part b? I can't seem to solve either part and don't see the connection between the two.
