Given the unbalanced equation: NaOH + H3PO4 ® Na3PO4 + H2O When the equation is correctly balanced, the coefficient of H2O will be 1)1 2)2 3)3 4)4 10. 2 Purpose of the Manual The objectives of this Manual are two-fold: (1) to provide guidance to industry and regulatory authorities for the development of accurate and consistent costs (capital costs, operating and maintenance expenses, and other costs) for air pollution control devices, and (2) to establish a standardized and peer reviewed costing methodology by which all air pollution. Given the reaction: C6H12O6 (s) + 6 O2 (g) 6 CO2 (g) + 6 H2O (l) How many carbon dioxide molecules are produced for every C6H12O6 molecule consumed? (1) 1 (3) 12 (2) 6 (4) 7 20. Use uppercase for the first character in the element and lowercase for the second character. The balanced equation will appear above. Given the unbalanced equation _Fe2O3 + _CO --> _Fe + _CO2. Choose the answer that is the sum of the coefficients in the balanced equation. The numbers in front of the chemical formulas are called coeffi-cients. The only time you'll see a number to the left of the formula for a chemical compound is when the compound is involved in a reaction, and you're looking at the equation for the reaction. Depth migration algorithms such as One-Way Wave Equation Migration and Reverse Time Migration are commonly used for imaging the earth's interior. Do not forget coefficients of "one". Is the equation C2H6 O2 yields CO2 H2O balanced? To be balanced it would be: 2 C2H6 + 7 O2 = 4 CO2 + 6 H2O What is the balanced equation for carbon dioxide and water?. We can multiply the number of waters on the product side by 4, to make 4 H20 molecules. Since we have O2 as the reactant, we can use a fraction as a coefficient to make the numbers come out right. Realize, however, that these coefficients represent the relative numbers of reactants and products, and, therefore, they may be correctly interpreted as ratios.
