- Generating CO2 for an Aquarium with Yeast. - Homebrew Talk
HI everyone, this is going to be a odd question but here goes I have a planted tank aquarium at home, in the aquarium hobby we occasionally build our own DIY CO2 generators using a yeast, sugar and water An example: Its a crude method but it works and saves us hundreds of dollars in
- Regulators: CO2, N2, O2, Beer gas - Homebrew Talk
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 my N2 tank, etc? I'm thinking that they're all just gas-pressure regulators and sold as CO2 or O2 in an attempt
- co2 Pressure (PSI) for force carbonating water - Homebrew Talk
Hi, I just got my DIY water carbonation system delivered I bought a 5 lb co2 tank, a corny keg, a bottle cap for carbonating in 2 liter bottles, and the 2 gauge regulator Went and had a CO2 tank filled And tried to carbonate a 2 liter bottle of water first with that cap But when I
- Confusing Threads on CO2 and Beer Gas Tanks - Homebrew Talk
CO2 regulators can be used on beer gas tanks, but beer gas is under higher pressure CO2 is liquid in the tank, and beer gas being a mix of Nitrogen and CO2 is just compressed gas and usually a full tank of beer gas is in the neighborhood of 3000 psi
- 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
- Reaction between NaOH and CO2 - Chemistry Stack Exchange
So I wanted to know what the reaction between sodium hydroxide and carbon dioxide can be, and upon research I got 2 answers The first one is $$\\ce{CO2 + NaOH(aq) - gt; NaHCO3(aq)}$$ and the seco
- Why does Co2+ have 7 electrons in the 3d orbital, and not 5 like Mn?
Electronic configuration of $\ce {Co}$ is as follows: $1s^2\ 2s^2\ 2p^6\ 3s^2\ 3p^6\ 4s^2\ 3d^7$ When Cobalt loses 2 electrons to become $\ce {Co^ {2+}}$ it loses the electrons which are in $4s^2$, not the ones in $3d^7$ because the electrons in $4s^2$ have a high reactivity So $\ce {Co^ {2+}}$ still contains 7 electrons in it's valence shell The new configuration of $\ce {Co^ {2+}}$ is $1s
- Why is carbon dioxide nonpolar? - Chemistry Stack Exchange
I understand that polarity corresponds to an electronegativity difference and that the larger the electronegativity difference, the more polar the bond However, I have read that carbon dioxide is
