Explain how to determine oxidation numbers. Oxidation Number: The specific number that will indicate the number of electrons remaining after undergoing oxidation or reduction (donated and accepted) by the atom to form a chemical bond is known as oxidation number. The ...
How to: Example 1: Find the oxidation number of C in CO2. The oxidation number of oxygen is always -2. So: C + 2 oxygen ions with a -2 charge each = 0 C + 2(-2) = 0 C - 4 = 0 C = +4 When you have a compound you can work out the oxidation numbers in two different...

These letters are based on a group of laboratory and engine tests that determine the oil’s ability to protect the engine from wear and high-temperature deposits and sludge. API has a full list of these standards here in case you’re curious, but make sure you’re buying an oil that’s...
To determine the amount of alcohol in that air, the reacted mixture is compared to a vial of unreacted mixture in the photocell system, which produces an electric current that causes the needle in the meter to move from its resting place. The operator then rotates a knob to bring the ...

Determine the number of valence electrons of each element by looking at the the oxidation number column of the chart in the resources section. Some elements have multiple oxidation numbers because there are a number of possible bond combinations between various elements. Use your judgment to determi...
