Ionic notation of calcium hydroxide solution? Ca(OH)2(aq) + CO2 (aq) -> CaCO3 (s) + H2O
Is that correct, so far? And can someone tell me the ionic notation with the charge?

Loading...Good afternoon, I still need a little help understanding the following task. I'm really looking forward to your helpful answers 🙋♂️ How do I even know that this is a solution of a weak conjugate acid-base pair? If I recognized this, I would know that I can use the Henderson-Hasselbalch equation to determine the pH…
I was titrating for my chemistry thesis, but forgot to measure the pH. The burette contained sodium hydroxide solution with a concentration of c=0.15 mol/l. In the Erlenmeyer flask below it, I had 10 ml of acetylsalicylic acid dissolved in ethanol (c=0.17 mol/l) and 3 drops of phenolphthalein as an indicator. It took 1.6 ml…
Suppose I first have an empty system, and then I add a single neutral Na and a single neutral Cl. Nothing else should happen here, right? The first ionization energy of Na is greater than the affinity energy of Cl, which means that the net energy to make both ions is positive, so you have…
Hello, How does one arrive at the oxidation number +3 Fe for FeBr3? For Br, I can understand that an electron is absorbed to form the noble gas atom krypton.
The gas cylinder for making sparkling water is empty again, and I want to buy a new one tomorrow. However, I'm going to a flea market before I can do my shopping, so my car might be sitting in the sun for a while. Could anything happen if the cylinder is left empty in the…
Hello, I've created a simple memory aid so that I can more quickly examine which spatial structure is present. For example, Bonding = 4, non-bonding = 0, 4+0= 4= tetrahedral etc. or you simply leave out the non-bonding element, e.g. H2O2 = bonding element = 3, non-bonding element = 4 = 3= triangle / planar…
