3. The sum of all oxidation numbers in a neutral compound is zero. The sum of all oxidation numbers in a polyatomic ion is equal to the charge on the ion. Example: In Fe2O3, the oxidation number of Fe is +3, and that of O is -2. The sum of all oxidation numbers is: +3 x...
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 ways. You can see ...

A driver might be found to have a level of 0.15, for example, while the legal limit is 0.08. To comprehend how we can gain access to such precise numbers, we have to ask ourselves: how does a breathalyzer work? What do those figures mean? And how do police officers find out if ...

If you want to see a hologram, you don't have to look much farther than your wallet. There are holograms on most driver's licenses, ID cards and credit cards. If you're not old enough to drive or use credit, you can still find holograms around your home. They're part of...
and processing. This identifier system consists of four digits, from 0004 to 3549. A total of 10,000 different United Nations numbers can be recorded. In the food industry, this system is also widely used, especially in the safety and transportation process of identifying and processing ...
How can one balance chemical equations with given oxidation numbers? If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? Aluminum is a main-group metal and therefore loses ...
