Bookmark or Share- Reaction between NaOH and CO2 - Chemistry Stack ExchangeThis question is a great opportunity to talk about state symbols, ionic bonding, and multi-step reactions. Very often when we write an equation for a chemical reaction we only look at the starting material and the products, like when you wrote the first form: $$\ce{CO2 + NaOH (aq) -> NaHCO3 (aq)}$$
- How to determine the equivalent weight of carbon dioxide correctly?My deal with the question: What am I doing wrong in the second method for finding the equivalent weight of $\ce{CO2}$ and if you wanna know why I added the equivalent weights of the elements was because I had read that for finding the equivalent weight of an electrolyte we add the equivalent weights of the cations and anions.
- Baking Soda + Citric Acid + Water = CO2, how much though?$$\ce{H+ + HCO3- -> H2CO3 -> H2O + CO2}$$ Let's start with a gram of sodium bicarbonate. How many bicarbonate ions are present? The molar mass of sodium bicarbonate is $84.0066\mathrm{\ g/mol}$, where a mole (mol) is a quantity equal to the number of carbon-12 atoms in 12 grams of carbon-12 or an Avogadro's number $(6.022\times 10^{23})$ of ...
- How can carbon dioxide be converted into carbon and oxygen?Thus two oxygen atoms and 1 carbon atom form a double bond between them so more energy is required to break this bond. In this way $\ce{CO2}$ is formed. For converting $\ce{CO2}$ back into carbon and oxygen atoms, $\ce{CO2}$ should be heated at almost $\pu{298 K}$ so carbon becomes gaseous and oxygen becomes part of air.
- How does Carbon Dioxide have a degree of freedom of 6?So since $\ce{CO2}$ has three atoms and is linear, it has 3*3 - 5 = 4 degrees of freedom which are independent of the global rotation and translation. We call these the vibrational modes. There's different ways you can decompose them, but the most useful one is 1) the symmetric stretch (both oxygens going out and in at the same rate while the ...
