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?

What is the oxidation state of each individual carbon atom in c2o42−?

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

Which of these describes how heat is transferred by convection* a. sunlight travels through space without the aid of fluids or solids. b. warm air rises and takes the heat with it, eventually, it cools and sinks c. air at the equator rises and sinks at the poles. d. air molecules touch the warm ground, heating them up *not conduction
