K 2 O + CO 2 K 2 CO 3 [ Check the balance ] Potassium oxide react with carbon dioxide to produce potassium carbonate. This will not happen unless the K2CO3 is heated first, and the K2O will react very quickly with H2O and CO2 to reform K2CO3. Find out more about how we use your information in our Privacy Policy and Cookie Policy. Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. Examples of complete chemical equations to balance: Fe + Cl 2 = FeCl 3; KMnO 4 + HCl = KCl + MnCl 2 + H 2 O + Cl 2; K 4 Fe(CN) 6 + H 2 SO 4 + H 2 O = K 2 SO 4 + FeSO 4 + (NH 4) 2 SO 4 + CO; C 6 H 5 COOH + O 2 = CO 2 + H 2 O 4) So erase the 2 you put in front of the K on the left side when you first started, and replace it with a 4. Compound states [like (s) (aq) or (g)] are not required. non-spontaneous, decomposition reaction.

Examples: Fe, Au, Co, Br, C, O, N, F.     Compare: Co - cobalt and CO - carbon monoxide, To enter an electron into a chemical equation use {-} or e. To enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}. The Potassium carbonate decomposes into CO2 and Potassium oxide when heated. The answer will appear below, Always use the upper case for the first character in the element name and the lower case for the second character. Potassium oxide react with carbon dioxide. If you do not know what products are enter reagents only and click 'Balance'. The equation is balanced. Yahoo is part of Verizon Media.
