Stoichiometry question: If you have a reaction that gives a 75% yield, how much product would you get if you add (for example: 3 g of vanillin + 3 mL of 10.6M acetic anhydride). First, determine which is the limiting reactant. Determine the molecular weight of the product. Determine how much product can be produced theoretically. Then, determine the actual yield when the reaction has a 75% yield.

Complete the stoichiometry of each reaction, making sure both stoichiometry and charge balance are correct. That is, find the values of the coefficients A, B, C, etc., for each reaction. Show your work and explain your reasoning. [2 Points each] (a) Oxidation of nitrite to nitrate (a chemoautotrophic process): A·O2 + B·NO2- = C·NO3- (b) Oxidation of organic matter using nitrite (a step of denitrification, a heterotrophic reaction): A·CH2O + B·NO2- + C·H+ = D·CO2 + E·N2 + F·H2O (c)...

II. Dimensions Involving Derivatives When we do dimensional analysis, we do something analogous to stoichiometry, but with multiplying instead of adding. Part A) Consider the diffusion constant that appears in Fick’s first law: J = −D dn dx. In this expression, J represents a flow of particles (the number of particles per unit area per second), n represents a concentration of particles (the number of particles per unit volume), and x represents a distance. We can assume that they have...

How do you do this? How do you set it up? One mole of a ideal gas initially at temp To=0C undergoes an expansion at a constant pressure of 1atm to four times it original volume. (a) calculate the new temp Tf of the gas. (b) calulate the wok done by the gas during the expansion.

1. Your stoichiometry reaction is C → 1/3 D A. You know the reaction order is second order in C. What is the rate law for this reaction? (Remember it has three parts) B. If the reaction rate is 0.150 M/s when the concentration of C is 0.800, what rate would you expect if the concentration of C is 0.400M? C. What rate of formation of D would you expect for your answer in part B (using the rate for...
