The mass of compound B that contains iron in its lower oxidation state is to be determined. Concept introduction: The redox reaction can be classified into three types depending upon the number of reactants and products as follows: 1. Combination redox reaction 2. Decomposition redox reaction 3. Displacement redox reactions Combination redox reactions are the reactions in which two or more reactants combine to form a single product. In displacement redox reactions, substances on both sides of the equation remain the same but the atoms exchange places in order to form the product while in decomposition reaction, one compound decomposes to form one or more product. A limiting reagent is the species that completely react in a chemical reaction and control the amount of product formed in the reaction. The calculation of product formed is done in accordance with the limiting reagent.

Interpretation Introduction

Interpretation:

The mass of compound B that contains iron in its lower oxidation state is to be determined.

Concept introduction:

The redox reaction can be classified into three types depending upon the number of reactants and products as follows:

1. Combination redox reaction

2. Decomposition redox reaction

3. Displacement redox reactions

Combination redox reactions are the reactions in which two or more reactants combine to form a single product. In displacement redox reactions, substances on both sides of the equation remain the same but the atoms exchange places in order to form the product while in decomposition reaction, one compound decomposes to form one or more product.

A limiting reagent is the species that completely react in a chemical reaction and control the amount of product formed in the reaction. The calculation of product formed is done in accordance with the limiting reagent.

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).
