  1. Why does Co2+ have 7 electrons in the 3d orbital, and not 5 like Mn?

    Aug 3, 2014 · We are currently going over coordination complexes, ligands and transition metal ions. In particular, this question is in regards to the ligand field stabilization energy. Why does Co2+ C o 2 + …

  2. Regulators: CO2, N2, O2, Beer gas - Homebrew Talk

    Oct 9, 2017 · Assuming that the low-pressure side adjusts to the value-ranges I want, is there any reason not to use something sold as an O2 regulator on my CO2 tank, the sold-as CO2 regulator on …

  3. If CO2 is nonpolar how come much more dissolves in water than O2?

    Jul 26, 2014 · CO2 has no dipole moment, but that doesn't make it nonpolar. The combined opposed dipole moments give the whole molecule a "quadrupole moment" meaning that if there is a 4-pole …

  4. How much do you pay for a CO2 tank? Refill? - Homebrew Talk

    Sep 30, 2012 · CO2 is CO2, there is no food grade CO2. My welding shop traded my 5 pound tank for a 20 pound and refills are $12. Refill costs are pretty much all labor, here are the prices for my tanks: 2 …

  5. How can carbon dioxide be converted into carbon and oxygen?

    Aug 8, 2012 · CO2 should be heated at room temperature so carbon becomes gaseous and oxygen becomes part of air. What the hell are you talking about? That is obvious nonsense and clearly …

  6. Baking Soda + Citric Acid + Water = CO2, how much though?

    Aug 10, 2015 · Baking soda (sodium bicarbonate) + citric acid react when mixed with water to form some amount of carbon dioxide gas ($\\ce{CO2}$). I am trying to determine what percentage of the …

  7. How to transfer Co2 from large tank to small tank - Homebrew Talk

    Dec 24, 2007 · I have a full 20# tank and two empty 5#s. The recent thread on tank filling inspired me to ask question: how do I transfer Co2 from the large tank to the small tank and is there safety risk …

  8. Why is carbon dioxide considered a Lewis acid?

    $\ce {CO2}$ is considered a Lewis acid. How it is an acid? According to Lewis: “species that accept an electron pair are acids”. But $\ce {CO2}$ can't accept electron pairs because oxygen and carbon ...

  9. reaction mechanism - Why NaOH (s,l) + CO2 (g) → Na2CO3 (s)? Why …

    Mar 5, 2024 · $\ce {2NaOH + CO2 <=> Na2CO3 + H2O}$ tends to favor more gas molecules with fewer atoms apiece, which is seen to be the left side (the sodium compounds, even if ionic, exist in the gas …

  10. What is the total bond energy of CO2? - Chemistry Stack Exchange

    Feb 7, 2016 · How can you calculate the total bond energy of $\\ce{CO2}$? I've searched for the bond energy of C=O and found it was 745 kJ/mol, but sometimes 799 kJ/mol. Which one is the right one to …
