Part 1. A slightly inflated balloon is placed about eight centimeters above a burning candle. Explain the change to the size of the balloon based on the kinetic molecular theory. Part 2. The same balloon is now placed in a bucket of ice cold water. Explain the change to the size of the balloon based on the kinetic molecular theory.

In both cases, assume the balloon is tied tight enough so that air does not escape.

Which of the following pairs of elements belong to the same groupa. h and he b. li and bec. c and pb d. ga and ge

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

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
