From Friday's work, we were practicing how to determine what an atom's oxidation number is. Looking at Friday's worksheet it is the opposite of the Gain/Lose column. But what does the oxidation number represent. An atom that loses one or more electrons will have a positive charge For example. Magnesium would want to lose its 2 valence electrons to complete an outer shell What does that oxidation of 2- mean?

In the cathode ray tube experiment, j. j. thomson passed an electric current through different gases inside a cathode ray tube in the presence of an electric field. in which two ways did this experiment change scientists’ understanding of the atom?

When the speed of the bottle is 2 m/s, the average maximum height of the beanbag is m.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
