If you do not know what products are enter reagents only and click 'Balance'. Enter either the number of moles or weight for one of the compounds to compute the rest. Substitute immutable groups in chemical compounds to avoid ambiguity. 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. By using this website, you signify your acceptance of, calcium hydroxide + carbon dioxide = calcium carbonate + water, Enter an equation of a chemical reaction and click 'Balance'. Home Reactions Blog. In many cases a complete equation will be suggested. Find out more about how we use your information in our Privacy Policy and Cookie Policy. K 2 O + CO 2 K 2 CO 3 [ Check the balance ] Potassium oxide react with carbon dioxide to produce potassium carbonate. Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. Log in: Chemical reactions Сhemical tables. The Potassium carbonate decomposes into CO2 and Potassium oxide when heated. Information about your device and internet connection, including your IP address, Browsing and search activity while using Verizon Media websites and apps. 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 Compound states [like (s) (aq) or (g)] are not required. 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. 5) Now, you have 4 K's and 2 O's on both sides.
