Write separate reactions — called half-reactions — for the oxidation and reduction processes and include the electrons. The Mn(+7) in MnO4(-) becomes Mn(+2) by taking on five additional electrons (7 - 2 = 5). Any oxygen in the MnO4(-), however, must become water, H2O, as a by...
as you know by now the typical steps to balancing a redox reaction don't work well. (1) identify the oxidiation states of every atom (2) determine which atoms are oxidized and which are reduced (3) write half reactions (including e's) ...

In the end, the reason is simple: I decided to write this post and record a podcast to help out one of my audience members.Here’s what this struggling student wrote:“Hi Anthony. I want to memorize some physics, chemistry, and math formulas, and also some texts that I have to ...
First order reactions are reactions whose rate depends on the reactant concentration raised to the first power. This means that when the concentration of a reactant is doubled so is the rate. Many decomposition reactions are first order. An example is the decomposition of N2O5: ...

I need to ask about your work with Ariana Grande too, having just seenWicked. I haven't seen it, but I want to! Everyone’s talking about it. Did you work directly with her on "Imagine?" Yeah. We all went to New York for a week. I write really fast, so we wrote tha...
My water chemistry settled down almost right away, but then I awoke this morning to a few of the dreaded white spots on the molly. I knew the “rescue fish” had been treated for ich a couple months prior to when I acquired them – the concerned roommate of their former neglectful ...
that I envisioned, Kean explains that we are really the final result of a rather remarkable chain of events and chemical reactions that began in the hearts of ancient stars burning bright and eventually created all the elements that came together to form the Earth and everything that inhabits ...
