C Place a 2 only in front of the Ca . Consider the equation: Ca+O2→CaO What needs to be done in order to balance the equation? The chemical equation for this reaction is Ca + O2 CaO. Relevance. O. O. Answer link. it needs 2 electrons to complete it's octate. Substitute immutable groups in chemical compounds to avoid ambiguity. Vous pouvez modifier vos choix à tout moment dans vos paramètres de vie privée. 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. Calcium reacts with oxygen to form calcium oxide. Answer Save. Сalcium react with oxygen. 5 years ago. Actually the calcium has valency 2 i. e. it has 2 electrons. Advertisement. Favorite Answer. See answer soccerjessi8 soccerjessi8 Answer: D. Explanation: I took this class last year seems right. But on the other side you only have: Ca. Balanced equation: 4 Ca(s) + O 2 (g) = 2 Ca 2 O Reaction type: synthesis. Chemical reaction. 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. Calcium combustion in air. This is the balanced reaction (it's ok to have fractions as the coefficient). This is due to Calcium being oxidation state +2 and Oxygen oxidation state is -2, this means … Pour autoriser Verizon Media et nos partenaires à traiter vos données personnelles, sélectionnez 'J'accepte' ou 'Gérer les paramètres' pour obtenir plus d’informations et pour gérer vos choix.

The energy term would be on the right-hand side: carbon reacts with oxygen to yield carbon dioxide and heat. Ca + O2 + C = CaCO3; Ca + O2 + H = Ca(OH)2; Ca + O2 + H2 = (Ca(OH))2; Ca + O2 + H2 = Ca(OH) Ca + O2 + H2 = Ca(OH)4; Ca + O2 + H2O = Ca(OH)2; Ca + O2 + P = Ca3(PO4)2; Ca + O2 + P4 = Ca3(PO4)2; NaBrO + H2O = NaBr + OH; CH3OH + CLO3 = CO2 + H2O + CLO2; CoCl2 + NaCl = Na2(CoCl4) K3(Fe(CN)6) + H2SO4 + H2O = K2SO4 + Fe(SO4)3 + N2O5 + CO2 + H20; Recently Balanced Equations Also metals generally show the tenancy to loose electrons. c Ca + O2. Textbook Solutions 6493. 9 years ago. O. Hence, 2Ca+O2=2CaO O. (Points: 1) a Ca. Hope that helped future questions too! Lv 7. At the same time oxygen is a non metallic element and it has also valency 2 i.e. Examples of complete chemical equations to balance: Fe + Cl 2 = FeCl 3 So you need to incorporatw your second O but you also need to make it so all the bonds are full. What is the reactant, or what are the reactants, in the equation? Concept Notes & Videos & Videos 104. 3. CISCE ICSE Class 7. Anonymous . See above you have: Ca.
