Trey and his friends are walking home when they get caught in a thunderstorm. they decide to find shelter to get away from the rain and lightning. after looking around, they see two places they can go: a wooden gazebo or an aluminum shed. trey has studied physical science and tells his friends they should stand under the wooden gazebo. which best describes why trey and his friends should go to the gazebo to be safe from the thunderstorm? a. if enough rain falls on the shed, the aluminum's property of tarnishing easily could cause the shed's door to be sealed shut. b. if lightning strikes the shed, the aluminum's property of fracturing easily under pressure could cause the shed to collapse. c. if lightning strikes the shed, the aluminum's free-floating electrons could easily conduct the electricity throughout the shed. d. if enough rain falls on the shed, the aluminum's free-floating electrons will lose their charge and attract lightning to strike the shed.

C. If lightning strikes the shed, the aluminum's free-floating electrons could easily conduct the electricity throughout the shed.

Explanation:

In metals there are many free flowing electrons that are shared by the metallic cation. The valence electrons are delocalized throughout the metal and therefore they can conduct electricity when lightning strikes the shed. Metallic bonds are different than covalent or ionic bonds.

In covalent bonds the electrons are shared between a pair of nonmetals. In ionic bonds electrons lost by the metal atom is gained by the non-metal thus giving rise to electrostatic forces of attraction between them.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
