I have been teaching chemistry and physics for about 14 years and look forward to helping out wherever I can to help you learn.
How is electricity similar to water flowing in a hose?
How is electricity mechanically produced in a power plant?
What is an electron-transfer reaction?
Why did chemists find it necessary to invent oxidation states?
Draw a Lewis dot diagram for $\mathrm{NF}_{2} \mathrm{H}$, and use the oxidation-state method of electron bookkeeping to determine how many electrons each atom should be assigned.

In the development kitchen for Gatorade, a food chemist was preparing a new flavor by measuring out 0.0350 mol of each ingredients into separate beakers. The fire alarm sounded after the first amount was placed and the chemist left without labelling the beaker. Because this happened late on Friday afternoon, the chemist left for home and came back on Monday. After the weekend the chemist didn’t remember what substance was placed in the beaker, but has the information below.
C3H7OH
How many moles of magnesium are in 5.00 g of MgO?
