The gas-phase reaction between nitrogen and oxygen was carried out in a device designed to maintain constant pressure. there are two cylinders of equal volume with a reaction arrow between them. the cylinder on the left has two molecules of o 2 and two molecules of n 2. the cylinder on the right has four molecules of n o. a constant pressure is applied to both cylinders write the balanced chemical equation for the reaction between nitrogen oxygen. include physical states.

How have the competing explanations' experiments on atoms affected the development of the atomic model?

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.
