So if I now consider the following: Do all the Cs of the main chain point behind the projection plane? Actually, it should alternate forward and backward at an angle of approximately 111°,…
I wasn't sure whether I should use only the mass of the individual oxygen atoms for the mass value, or whether I should use the molar mass of the entire molecule or just the oxygen atoms within it. I've now divided the 10.25g by the molar mass of the oxygen atoms, not the entire molecule….
What happens when NaCl reacts with HCOOH? Can HCl be produced this way? Is the reaction exothermic, or is an activation energy required? Can any other byproducts besides NaHCOO and HCl be formed? (NaCl + HCOOH -> NaHCOO + HCl) I would be happy to receive any professional feedback!
I have an exercise where 0.22 mol HCO2Na and 0.15 mol HCl are mixed in a volume of 1L. Now I'm supposed to calculate the concentrations of H^+, HCO2^-, and HCO2H. However, I'm not sure how to determine the concentration of the H^+ ions. I tried calculating the pH value and then using it to…

Nö. Magesium is freely available.
No, just money. Magnesium citrate should be good
But this is not an elementary magnesium…
The FS has written that he needs elementary.
