3. Also oxygen in its original state is O2 so there when first put equation together it reads - Ca + O2 --> CaO but you then need to balance the equation to ensure there is the same number of moles of each element on each side of the equation therefore giving 2Ca + O2 --> 2CaO. Hi, the answer you are looking for is 2Ca + O2 --> 2CaO. Ca + O2=CaO.

To balance the above equation we should multiply by 2 on both the sides. Consider the equation: Ca+O2→CaO What needs to be done in order to balance the equation? O. O. B Place a 2 in front of the CaO only. 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. Question Bank Solutions 6585. Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. Write the word equation, including an energy term, for this reaction? (Points: 1) a Ca. In many cases a complete equation will be suggested. Also metals generally show the tenancy to loose electrons. Enter either the number of moles or weight for one of the compounds to compute the rest. ChemTeam. Hence, 2Ca+O2=2CaO d CaO. For the best answers, search on this site https://shorturl.im/axxJ6. This reaction takes place at a temperature of over 300°C. Calcium reacts with oxygen to form calcium oxide. 2Ca+O2 = 2CaO. The chemical equation for this reaction is Ca + O2 CaO. Syllabus. Calcium combustion in air. Enter either the number of moles or weight for one of the compounds to compute the rest. Answer link. The energy term would be on the right-hand side: carbon reacts with oxygen to yield carbon dioxide and heat. Anonymous . c Ca + O2. What is the reactant, or what are the reactants, in the equation? Is the mass of the reactants always equal to the mass of the products in a chemical reaction? Write word equation … See answer soccerjessi8 soccerjessi8 Answer: D. Explanation: I took this class last year seems right. But on the other side you only have: Ca. D Place a 2 in front of the Ca and the CaO . But on the other side you only have: Ca. Reaction stoichiometry could be computed for a balanced equation. Сalcium react with oxygen. So you need both O's and two Ca's, so you end up with. Would energy belong before the equal or after the equal sign? Hope that helped future questions too! This is the balanced reaction (it's ok to have fractions as the coefficient). A Place a 2 in front of the O2 and the CaO . Actually the calcium has valency 2 i. e. it has 2 electrons. Ca+O2=CaO. Reaction stoichiometry could be computed for a balanced equation. C Place a 2 only in front of the Ca . Compound states [like (s) (aq) or (g)] are not required. Write Word Equation for the Following Skeletal Equation: Ca + O2 → Cao - Chemistry . Сalcium react with oxygen to produce calcium oxide. 1 Answer. O. This is due to Calcium being oxidation state +2 and Oxygen oxidation state is -2, this means … Advertisement.
