If a balloon with a volume of 25.4 liters at a pressure of 1 atm is taken to the bottom of a 68 ft pool (34 ft of water= 1 atmosphere) how many atmospheres of pressure are now pushing on the balloon? What is the new volume of the balloon at the depth?

The big bang nucleosynthesis theory states that elements were produced in the first few minutes of the big bang while elements have their origins in the interiors of stars, forming much later in the history of the universe.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same
