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 ...
Re: How to infer the strength of an oxidizing agent from its Lewis structure? « Reply #4 on: June 09, 2010, 05:35:58 AM » Read up on how to determine oxidation states.CrO3 has an oxidation state of 0, due to the chromium's oxidation state of +6 (to counter the -6 from ...

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...
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 ...
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 ...
Administering iodine containing contrast agents can have noxious effects on the microbiota by binding to the amino acids tyrosine and histidine on the bacterial membrane, as well as by oxidation of cytoplasmic and membrane components [4]. Excess intake of iodine triggers the Wolff-Chaikoff effect, ...
