Hello chemists. Given: Acetic acid/ citric acid/ HCl; NaClO; water in a container. Plan: If I react NaClO with one of the three acids mentioned above, HClO + Na compound is formed (alkaline, except for NaCl). With HCl, an acidic environment is created and with the other two acids, a basic environment is created. I…
Why is O the central atom in the structural formula of HOCl, even though Cl can actually form more bonds? And how do I know in which "form" I have to record the structural formulas? thank you 🙂
Which endothermic and exothermic reactions are used in everyday life?
Hi, I want to calculate the mass with m=V•p. My volume is 25 mm3 and the density is 2.70 g mL to the power of -1. Do I need to convert the density? If so, how? Can anyone help me? Thank you. Best regards!

Potassium and sodium have a lonely electron in the outermost path and are therefore very reactive and occur in the form of salts and alkalis. This group of alkali metals also includes lithium and the rarer elements Rubidium, Caesium and Francium.
Magnesium and calcium have two electrons left and are called alkaline earth metals because their compounds are less soluble and therefore more earthy. These include beryllium, strontium, barium and radium.
these are all metals
