(5) combine half reactions and cancel e's (6) rearrange as needed and add counter ions (7) add any remaining chemical species... then balance them why doesn't it work well? *** 1 ** on the left Mn in MnO4(2-) is +6
I have performed these reactions neat without base in the past when doing the same reaction in solvent with base didn’t work, but it’s certainly not a universally compatible method. In general I would definitely agree, these reactions tend to go much better with than without.OP, another t...

"The prevailing assumption is that these metal atoms are strongly bonded to each other and simply provide 'landing spots' for reactants. What everybody has assumed is that metal-metal bonds remain intact during the reactions they catalyze," says Mavrikakis. "So here, for the first time, we...
As most experiments are done in the regular atmosphere, you can add O2 if necessary to burning reactions. If the equation is reversible, make sure it has a double-arrow to represent that. Step 4 Balance your equation. This is where the Law of Conservation comes into play: think of the ...
Question: How does mass change during a chemical reaction? Building Blocks Of Matter: All matter is made up of tiny building blocks called atoms. Atoms are bonded together to form molecules and compounds, which make up everything that exists in the universe. The amount of matter in a substan...
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 ...
Second, we attempt to show how the existence of views of science in textbooks and of chemistry teachers contributes to an impoverished image of chemistry. A varied design has been elaborated to analyse some epistemological deficiencies in teaching acid–base reactions. Textbooks have been analysed ...
Slime is a sticky, gooey substance that’s fun to touch and great to use for teaching about viscosity and chemical reactions. When kids make slime,they can learn about how different chemicals react with each other to create something new.They can also learn abouthow adding different amounts ...
We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To supp
