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

Select all of the statements which are true. electrons are located in shells or orbits around the atom. electrons orbit slowly around the atom. electrons travel in one flat path around the nucleus of an atom. the valence of an atom is determined by the number of electrons in the atom's outermost shell.

Measurements that have similar values are: a. usually accurate b. sometimes accurate c. always accurate d. never accurate

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.
