Mayhem replied to the thread Side reactions while dissolving silver.Your descriptions a little hard to follow. Gardening is irrelevant to the chemistry. What I'm seeing is Step 1: H2SO42 (aq) +... -
Mayhem replied to the thread Side reactions while dissolving silver.Impossible to say without knowing what corrosion inhibitor is in the product. Am I correct in assuming that 'lavender' refers to pale... -
Mayhem replied to the thread Gamma Radiation and Electrolysis.First of all it's H2O, not H20. To chemists, using 0 in place of O is like using n in place of π is to physicists. Anyway. Gamma... -
Mayhem reacted to Borek's post in the thread Racemic mixtures versus achiral compounds with
Informative.
Louis Pasteur (of the vaccination fame) separated racemic mixture of tartaric acid by drying it out and patiently sorting crystals under... -
Mayhem replied to the thread Why is AuCl4 an anion?.Granted, this approach is only strictly valid if you have knowledge of the bonding, but it is typically always valid for complexes of... -
Mayhem replied to the thread Chemistry Why percent yield sometimes less than 100% in chemistry experiments?.I see what you are asking. Understand that the problem you stated in the thread title is opposite of what actually meant to ask. When... -
Mayhem replied to the thread Chemistry Why percent yield sometimes less than 100% in chemistry experiments?.Small thing. Percent yield = (actual yield / theoretical yield) * 100. Without the 100 factor, you just get a ratio, not a % expression. -
Mayhem replied to the thread Why is AuCl4 an anion?.Both AuCl3 and [AuCl4]- exist. Chemistry principles get funky when you get to the third row metals (where Au sits) so I can't comment... -
Mayhem replied to the thread Chemistry Which of the following will decrease CO bond character?.Unless Ir is special for this, any option will change the bond properties of the CO ligand, even if the change is small. To convince me... -
Mayhem replied to the thread Cyano substituted hydrazines.Energy storage is one of my areas of interest and indeed, energy density is a key parameter for storage viability. But reversibility... -
Mayhem replied to the thread Cyano substituted hydrazines.It is well known that a high nitrogen to carbon ratio in a molecule is a predictor of positive energetic properties. I can't find a... -
Mayhem replied to the thread Cyano substituted hydrazines.This is the only published article I could find, and googling 1,2-dicyanohydrazine (or N,N') only returns a few relevant links, one of... -
Mayhem replied to the thread Cyano substituted hydrazines.Please provide a reference to those articles. -
Mayhem replied to the thread Chemistry Understanding Reaction Quotient and Molarity.Careful with describing a "reduction" in reactants. Say decrease/increase instead. Between reactants and products, the only thing that...
