For an experiment, Yolanda rubs a cloth against a balloon and places the balloon next to running water. What happens? The balloon breaks from the pressure of the water. The charged balloon repels the water. The uncharged water is attracted to the charged balloon. The water spills over the balloon, and the balloon gets wet.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

Avariable that is not being directly tested during an experiment should be changed varied experimented controlled

Which of these is a physical property
