Putting the bottle in the freezer causes the air to down. Cooling causes matter to (take up less space), and causes particles to move and move . When removed from the freezer, the air in the bottle starts to up and gain . Because it is warming, the air will (take up more space). The particles move and move . The expanding gas exerts enough pressure on the coin to cause it to rise up on one side.

Which statement is usually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution. calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
