11. Balanced equation: 2 Rb(s) + 2 H 2 O(l) = 2 RbOH(aq) + H 2 (g) Reaction type: single replacement. Write balanced chemical equation for the following... "octane (C3H8) burns in oxygen gas to form carbon dioxide and water." Input Equation Balanced Equation; Rb(s)+H2O(l)=RbOH(aq)+H2(g) 2Rb(s) + 2H2O(l) = 2RbOH(aq) + H2(g) Rb + Br = RbBr: Rb + Br = RbBr: Rb + Br = RbBr: Rb + Br = RbBr Write balanced chemical equation for the synthesis of RbCl for RB and Cl2 13. Write a balanced chemical equation for the following... "When … Write a balanced chemical equation for the following... "calcium and oxygen react to form calcium oxide." The equation becomes, 14. This given equation is unbalanced, in order to balance this equation, multiply 2 with H2O and 2 with RbOH , The above equation can be written as, Rb(s) + 2H2O(l) → 2RbOH(aq) + H2(g) Total number of Rb in reactant is 2, in order to balance the total number of Rb in both the sides multiply 2 with Rb. 12. Reaction stoichiometry : Limiting reagent: Compound: Coefficient: Molar Mass: Moles: Weight: Rb(s) 2: 85.4678: H 2 O(l) 2: 18.01528: RbOH(aq) 2: 102.47514: H 2 (g) 1: 2.01588: Units: molar mass - g/mol, weight - g.
