- 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
- 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
- Converting volumes of CO2 to PSI? - Homebrew Talk
The CO2 pressure setting has nothing to do with the volume of beer being carbonated, and everything to do with the temperature of the beer and the desired level of carbonation As well, the amount of pressure exerted by a carbonated beverage on a sealed vessel doesn't change with volume, either
- 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
