Decades from now‚ the present method of supplying energy to households (i.e.‚ with electricity‚ gas‚ or o11) may not be possible. Instead‚ housepersons will shop for their energy in supermarkets (Figure P4.5).

lightness of the metal. Both of these metals are reactive with acids. The most common acid in they react with is hydrochloric acid. In this lab‚ we collected a gas produced in a reaction and compared it with the volume that was actually collected to the “target volume” we calculated at the beginning of the class using stoichiometry and the Ideal Gas Law. We had to figure out what the temperature of the room was because the laboratory was not under the conditions of STP. We were given two different elements

theory is that gas particles are always in motion‚ like the other states of matter. But they are different in that they undergo random translational movement. In solids‚ the particles mainly experience vibrational motion and in liquids they mainly vibrate and rotate‚ with some translational motion. Gas particles move rapidly in straight lines‚ unless acted upon by another particle or the walls of a container. This continuous contact with the container leads to our understanding of gas pressure‚ the
