Sodium diuranate  [show article only]hover over links in text for more info DRIVING FORCES AND DOUBLE REPLACEMENT REACTIONS. 1) The formation of water is the strongest driving force. In an ionic reaction where water is a product, it. is almost a certainty that a double replacement reaction will take place. 2) The formation of a precipitate (insoluble compound) is another indicator of a strong driving force. We will assume that if a precipitate is formed than the reaction will take place. 3) The formation of a nonionic (covalent) compound. Some examples would be carbon dioxide gas, oxygen gas, or ammonia. We will assume double -replacement reactions that produce a molecular. compound will occur.

Assay If the assay involves addition of exogenous reactants (the reagents), then their quantities are kept fixed (or in excess) so that the quantity (and quality) of the target is the only limiting factor for the reaction/assay process, and the difference in the assay outcome is used to deduce the unknown quality or quantity of the target in question.

- A limiting reagent is a chemical reactant that limits the amount of product that is formed. The limiting reagent gives the smallest yield of product calculated from the reagents (reactants) available. This smallest yield of product is called the theoretical yield. To find the limiting reagent and theoretical yield, carry out the following procedure: 1. Find the moles of each reactant present. 2. Calculate the moles of a product formed from each mole of reactant. 3. Identify the reactant giving the smaller number of moles of product. This reactant is the Limiting Reagent: 4. Calculate the grams of product produced by the Limiting Reagent. This is the theoretical yield. THEORETICAL YIELD The theoretical yield is the amount of the product in g formed from the limiting reagent. theoretically possible (same as Step 4 above). The actual yield is the amount of the product in g actually formed in the laboratory. The percent yield is the percent of the product formed based upon the theoretical yield.

- 5. Predict the theoretical yield. Multiply the number of moles of the limiting reactant by the ratio of the product's coefficient to the limiting reagent's coefficient,then multiply by the product's molar mass ratio.. Calculate the amount (in moles) of each reactant. To do this, divide each reactant's mass by its molar mass. 1  To calculate a molecule's molar mass, add the atomic masses of each atom in the compound.

- 4) Mass of product: Since the limiting reagent determins how much product is formed we use the moles of limiting reagent to determine the moles and mass of product: 5) Excess mass of reactant: !.56 moles of O2 was initially present and 0.63 moles were consumed in the reaction.ince we need 2 moles of B to completely react with 1 mole of A, we will run out of B first (there is only one mole of B available). Whatever reactant runs out first is called the limiting reactant or limiting reagent.

Limiting Reactants & Calculating Excess Reactants That is because, 5 mols of A will require 10 mols of B to react, but we only have 9! Therefore, in this case, B is the limiting reactant. The amount we have of B is not enough, it has limited how much we can react. The limiting reactant completely reacts, but the other reactant (A) does not.

Reducing agent The oxygen (O2) is being reduced, so it is the oxidizing agent. The glucose (C6H12O6) is being oxidized, so it is the reducing agent. In organic chemistry, reduction more specifically refers to the addition of hydrogen to a molecule, though the aforementioned definition still applies.

- Thus, the MnO 4 - ion acts as an oxidizing agent in this reaction. Oxalic acid, on the other hand, is a reducing agent in this reaction. By giving up electrons, it reduces the MnO 4 - ion to Mn 2+ .Atoms, ions, and molecules that have an unusually large affinity for electrons tend to be good oxidizing agents.Elemental fluorine, for example, is the strongest common oxidizing agent.eaker oxidizing agent. weaker reducing agent. On the basis of many such experiments, the common oxidation-reduction half-reactions have been organized into a table in which the strongest reducing agents are at one end and the strongest oxidizing agents are at the other, as shown in the table below.
