Chemical Reactions with Isotopes The coefficients in a balanced chemical equation represent the relative numbers of each molecule or formula unit and the relative number of moles of each molecule or formula unit. In a balanced equation, the stoichiometric relationships among the substances allow us to convert between quantities of reactants and products in a reaction. Deuterium Deuterium (written as D or 2H) is an isotope of hydrogen known as heavy hydrogen. PART A QUESTION: Balance the given chemical equation...

3 pts It is handy to have an equation to quickly determine the number of atoms left in a radioactive sample as a function of time. For this we can divide the initial amount by two for every half-life of time, the following equation does exactly that: N No (24/01/2) N, 2 1/2 where N is the initial number of atoms at t=0, t is time passed and is the half-life. Use the above equation to help you answer the...

Question 1 6 pts Consider a hypothetical, non-linear molecule with three atoms. The symmetry number (o) is 1. The three vibrational wavenumbers are 1,071 cm 1, 1,385 cm 1 and 1,254 cm 1. Use Yates & Johnson equation 5.52 (and a finite difference approximation of the differential) to compute the contribution of vibrations to the molar internal energy at T = 435 K. Note: this assumes that the molecules are noninteracting. Uvid = — mo Note: the required precision is...

Problem 2: Below are several chemical equations. For each equation, identify which atoms are oxidized and which atoms are reduced. It is possible to have a type of atom that is both oxidized and reduced in the same chemical process. (How? Assign oxidation numbers to each element on both sides of the equation. If the number goes up, the atom is oxidized. If the number goes down, it's reduced.) a. N2(g) + 2 O2(g) → 2 NO2(g) b. CH4(g) +...
