Problems presented in this paper concern the chemical equilibrium of methyl alcohol, formic acid, and methyl formate when combined.

This thesis explores the Hicoria genus and focuses on the Stuart variety of pecan tree. Experimentation yielded the ash constituents, fats, fat constants, crude fiber, protein, and sugar in shelled pecan samples.

This thesis explores the seperation of isomeric paraffins in organic chemistry and how the resulting mixture of hydrocarbons might be examined.

This thesis presents the results of an experiment conducted to discover if selenic acid or monazite sand are possible catalysts that can be used for the alkylation of isobutane and isobutene.

This thesis examines the reactions of hydrocarbons exposed to chlorosulfonic acid in order to establish the reaction rate and associated molecular structure of each compound.

This thesis presents findings of experiments conducted to determine the most feasible method to electroplate metal.

This comparative study attempts to determine the importance of soil fertility in determining how much of an element a plant absorbs.

This study examines history, climate, and distribution in relation to the chemical content of yellow dent corn.

A study to determine the organic content of Lake Dallas, and study the influence on plankton growth.

This thesis explores the chemical contents of post oak and willow trees. Samples of each tree are compared to determine the amount of sulfur, phosphorus, potassium, sodium, silicon, iron, aluminum, calcium, magnesium, and manganese in them. Results indicated usefulness of each tree to humans.

A chemical analysis of representative samples of Windthorst sand, Denton sand, and Denton clay has been made, and this analysis shows that their composition has a strict correlation with respect to their geological origins. The analyses of the different soils have shown the Windthorst sand to be highly deficient in all of the essential elements, whereas the Denton sand is deficient in only one; namely, phosphorus. The analysis of the Denton clay showed it to be highly fertile. From the consideration of the pH and the lime content, it has been determined to some extent what crops will grow in each of the soils.

The purpose of this paper is to investigate the Kjeldahl method of nitrogen determination.

In this thesis, the process involved in the precipitations and separations of the metal of Group II and Group III studied. Suggestions have also been offered whereby students can make an analysis without loosing metals in the initial precepitation.

This study investigated mercury-sensitized photochemical action on a mixture of isobutane and isobutene. Flow runs of isobutane-isobutene 3.2.1 mercury-saturated gases illuminated with unfiltered radiation of mercury vapor lamp gave no detectable change to hydrocarbons heavier than C4 at reaction tempratures of 27C. and 99C.

This study attempts to discover what types of errors are commonly made by students in freshman chemistry classes. It considers the errors resulting from the students' lack of knowledge of the subject taught, and errors attributed to their failure to use correct English in their expression of ideas.

The purpose of this study is to collect sample soils from uncontaminated horizon (by digging completely through the soil profile or strata) and provide a chemical analysis of the important soils of Dimmit county, Texas.

The purpose of this study is to investigate the rate of natural fermentation of solutions at different temperatures. Whatever microorganisms that chanced to be present in the air and that chanced to fall into the inoculating medium are the ones which brought about fermentation when transferred to the fermentable solution.

This study attempted to determine hydrocarbons in the crude oil by comparing the results obtained using the two methods of analysis: chemical analysis and Kurtz-Headington analysis. The Kurtz-Headington analysis was found to be adequate to determine hydrocarbons in the crude oil.

The purpose of this study is to determine the amounts of the element sulfur, phosphorus, sodium, potassium, silicon, iron, aluminium, calcium, magnessium, and manganess found in the roots, hearts, sap, leaves, and bark of two plants, the short leaf pine and the blackjack oak.

The purpose of this study was to analyze the different soils in Denton, Texas. For the purpose of this study, the soils of Denton County are divided into three general groups with respect to origin: 1)those formed in place by the weathering of consolidated rocks, 2) those formed from the weathering of unconsolidated rocks, and 3) alluvial soils. A chemical analysis of representative samples of Bell Clay, Kirvin fine sandy loam, and San Saba clay has been made, and shown to have a strict correlation with their respective geological origins.

A sample of the surface-well water was taken from an area of the predominating soil of each of the three geological regions of Denton County, Texas, and a chemical analysis of each sample was made. This thesis deals with the area from which the samples were taken, the methods of analysis used, and the results of the analysis.

The purpose of this investigation is to attempt by correlation of chemical-physical factors to ascertain if any one of the necessary features might act as a factor limiting growth and reproduction of either plants or animals. The body of water used in this investigation is Eagle Mountain Lake, a reservoirs approximately five years of age.

The purpose of this study was to determine the chemical content of Denton County's (Texas) water. Based on the analysis of the three samples, the water of Denton County is classed as poor for irrigation.

This thesis aimed to study some of the general principles underlying electrodeposition together with experimental facts regarding the effects of changing constituents of the plating solutions, variations in hydrogen-ion concentrations, and variation in current density used in the electrodeposition of lead.
