Homework Answers
a) we know that for the formations in thermodynamics we need only elements as the reactants. As the formation reations are defined as the reaction in which one mole of compound is formed from constituting elements.
b) we can identify the reactants with the help of the compopund being formed. The elements which constitute the compound will be the reactants for the formation reaction of the compound.

Question 6 1 pts Mark all of the statements that are TRUE for the limiting reactant in any chemical process. You must know the balanced equation for the reaction to determine the limiting reactant The limiting reactant limits the amount of product(s) formed. The limiting reactant is present in the smallest mass. The limiting reactant leads to the formation of the smallest amount of product. The limiting reactant is completely consumed during a chemical reaction. Question 7 1 pts Take...

In a chemical reaction, the reactant that limits the amount of product that can be formed is called the limiting reactant (or limiting reagent). The reaction will stop when all of the limiting reactant is consumed. In the sandwich example, bread was our limiting reactant. The reactant or reactants in a chemical reaction that remain when a reaction stops when the limiting reactant is completely consumed are called the excess reactant(s). The excess reactant(s) remain because there is nothing with...

1. Moles of Reactant to Mass of Reactant: Identify the iodide ions and ozone in the balanced chemical equation. Use mole ratio, then convert to grams. A method used by the EPA for determining the ozone concentration in the air is to pass an air sample through a bubbler containing iodide ions. The iodide ions remove the ozone according to the following reaction: O3(g) + 2 I-(aq) + H2O(l) → O2(g) + I2(aq) + 2 OH-(aq) How many grams of ozone...

Objective Find the ratio of moles of reactant to moles of a product for the reaction below. Compare mass and mole amounts of reactants to determine the amount of products that can be/are made. Background Chemical reactions are represented by balanced chemical equations. Proper interpretation of an equation provides a great deal of information about the reaction it represents and about the substances involved in the reaction. For example, the coefficients in a balanced equation indicate the number of moles...
