A. True. The ozone layer is very critical to our health.
Chlorine, Cl , is located in period 3, group 17 of the periodic table, and has an atomic number equal to 17 . This tells you that a neutral chlorine atom will have a total of 17 electrons surrounding its nucleus. Now, notice that the first energy level doesn't not contain a p-subshell,
2 m/s
Explanation:
The distance to school is 14.4 kilometers which are equal to 14400 meters.
Amy takes 40 minutes which are equal to 40 × 60 = 2400 seconds to arrive at school.
Bill takes 40 + 20 = 60 minutes which are equal to 60 × 60 = 3600 seconds to arrive at school.
Amy’s average speed = distance (m) / time (s)
Amy’s average speed = 14400 m / 2400 s = 6 m/s
Bill’s average speed = 14400 m / 3600 s = 4 m/s
How much faster (in meters/second) is Amy’s average speed for the entire trip?
Amy’s average speed - Bill’s average speed = 6 m/s - 4 m/s = 2 m/s
