The diagram has to be chosen for from the diagrams II through IV that is consistent with the product that is formed from the reaction mixture depicted in diagram I and associated with balanced chemical equation. Concept Introduction: Statement that uses chemical symbols and formulas instead of words in order to describe the changes that takes place in a chemical reaction is known as chemical equation. Reactants are the substances that are present in starting of the chemical reaction and it is entered in left side of the chemical equation. Products are the substance that is obtained from the reactants as a final outcome of the chemical reaction and it is entered in right side of the chemical equation. In order to write a chemical equation four conventions are used and they are, Correct formulas of the reactants are written in left side of chemical equation. Correct formulas of products are written in right side of chemical equation. An arrow is placed between reactants and products which point towards the products. If two or more substances are present in reactant and product, plus sign is used to separate them. Balanced chemical equation is the one that has equal number of atoms of each element that is involved in the chemical reaction on both sides of the chemical equation. An unbalanced chemical equation can be balanced by adding coefficients to the equation. It is a number that is placed in left side of the chemical formula so that it changes the amount only and not the identity.

Solution Summary: The author explains that chemical equations use chemical symbols and formulas instead of words to describe the changes that take place in a chemical reaction.
Definition Definition Transformation of a chemical species into another chemical species. A chemical reaction consists of breaking existing bonds and forming new ones by changing the position of electrons. These reactions are best explained using a chemical equation.

Interpretation Introduction
Interpretation:
The diagram has to be chosen for from the diagrams II through IV that is consistent with the product that is formed from the reaction mixture depicted in diagram I and associated with balanced chemical equation.
Concept Introduction:
Statement that uses chemical symbols and formulas instead of words in order to describe the changes that takes place in a chemical reaction is known as chemical equation. Reactants are the substances that are present in starting of the chemical reaction and it is entered in left side of the chemical equation. Products are the substance that is obtained from the reactants as a final outcome of the chemical reaction and it is entered in right side of the chemical equation. In order to write a chemical equation four conventions are used and they are,
Correct formulas of the reactants are written in left side of chemical equation.
Correct formulas of products are written in right side of chemical equation.
An arrow is placed between reactants and products which point towards the products.
If two or more substances are present in reactant and product, plus sign is used to separate them.
Balanced chemical equation is the one that has equal number of atoms of each element that is involved in the chemical reaction on both sides of the chemical equation. An unbalanced chemical equation can be balanced by adding coefficients to the equation. It is a number that is placed in left side of the chemical formula so that it changes the amount only and not the identity.

There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
