With work pls a beach ball is inflated to standard atmospheric pressure. a diver then takes the ball underwater to a depth of 25 meters, but its winter and the water is cold! the original volume at 1.0 atm is 25.8 L , and the air temperature is 23 C. total external pressure is 3.5 atm. calculate the new volume of the beach ball.

Idid a lab for chemistry where we put nails in a copper (ii) chloride solution. 1. why did the reaction stop? which reactant was used up? how do you know? 2. describe what was happening to the atoms of iron and copper during the reaction. what is this type of reaction called? 3. what would happen to the ratio of copper to iron if you had placed more nails in the beaker? if you had let the reaction go for less time? 4. what is the accepted ratio of copper atoms to iron atoms in this reaction? account for differences between your experimental value and the accepted value. write the balanced equation for the reaction.
