Nuclear Transmutations (Section)
Complete and balance the following nuclear equations by supplying the missing particle:
(a) 25298Cf + 105B→3 10n + ? (b) 21 H + 32 He→42 He + ? (c) 11 H + 115B→3? (d)12253I→12254Xe + ? (e) 5926Fe→ 0-1e + ?
General Chemistry CHM-2045 Chapter 3 “Balancing Equations” Study Guide BALANCING CHEMICAL EQUATIONS: A balanced equation is one in which the same number of atoms of each element appears on EACH side of the equation. In order to balance equations, CORRECT stoichiometric coefficients must be assigned. Stoichiometry: RELATIONSHIP between amounts of reactants and products. 4 Al (s) + 3 O2 (g) 2 Al2 O3 (s) Numbers listed in front (in RED) are the stoichiometric coefficients. How to balance chemical equations: Step 1: Write correct formulas for the reactants and products. Here propane and oxygen are the reactants, and carbon dioxide and water are the products.
