When formulating a reaction equation from a text, it's certainly helpful to work with the valences of the elements. However, this isn't possible with tungsten(VI) oxide. This should be done purely according to logic, W206. Addendum/insight: Could it be that they are shortening it, so that W2O6 becomes WO3?
Using the example of alpha-glucose and galactose (as shown in the figure from my book), can someone explain to me whether and why the formula (shown in the figure) in the top right corner for alpha-glucose is NOT sufficient to ensure that it might not be galactose? Why do you need the lowest representation to…
So the rotation is exactly around the axis that connects the CH3 and H atoms with the two C atoms in the middle (the ones with the double bond), right? And this is a case of CONFIGURATIONAL isomerism and NOT CONFORMATIONAL isomerism, because rotation at the single bonds CANNOT make the two molecules equal, right?…
The chemical bond types are simple A) Si- must be covalent Csf-ionic Ne- stable (I would put it this way) Cu-metallic …bond. B)I usually know such diagrams with the energy level occupancy and not as a charge density distribution of the valence electrons. Question 1: Is the charge density distribution higher at c than at…
In my biochemistry book, the explanation of the amino group states, among other things: "In contrast to alcohols, nitrogen can react with a fourth carbon atom via its lone pair of electrons, forming the quaternary, positively charged ammonium ion." My question: Why can't an oxygen do the same, i.e. form another bond, even though the…
So does the + that is located right above the "N" of the nitrogen atom in the valence bond formula mean that the whole molecule is positively charged, or does it mean that the nitrogen atom is positively charged, or does it mean that the nitrogen atom is positively charged and at the same time…
What ingredients does cream of tartar/cream of tartar consist of? The ingredients list only potassium hydrogen tartrate, but there must be more in it, right? Cream of tartar is used as a baking powder substitute, so it can't just contain potassium, right?
I wanted to do the “flying can” experiment I wanted to calculate how much aluminum foil I need to put in naoh to fill the can to the brim with H and I calculated the following: You can imagine the word mass ratio away The circled is the volume of the can The result is…
Is there software where you enter what should be burned and the software outputs what combustion gases are produced? I want to know what happens when I try two smoking products. The first consists of: A rolled cigarette roller containing: a bit of dried blue lotus flower (Nymphaea caerulea) and a bit of cannabis. The…
Hello, I would like to know how the reaction shown in Figure 2 can produce the by-products shown For by-product C I would have thought of an azo coupling Thank you for your help and support
