Carbonate dot and cross diagram
WebI can't get the electrons to add up at all in the CO 3 and I'm completely lost where the Na comes into it, but this might be because I'm completely wrong about how it's all together. ! The carbonate ion is CO32-. so the total number of valence electrons is: C = 4. 3 x O = 18. 2 minus = 2. ------------. 24 electrons. WebCarbonatation is a slow process that occurs in concrete where lime ( CaO, or Ca (OH) 2( aq)) in the cement reacts with carbon dioxide (CO 2) from the air and forms calcium …
