Mercury-Sensitized Photochemical Action on a Mixture of Isobutane and Isobutene

Description: 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.

Molecular Dimensions

Description: This study attempts to calculate the areas of the cross section and diameter of the CH3 group, COOH group, the length of the carbon chain, and the longtiudinal distance between carbon atoms for each of the three acids. It also attempts to develop a method of measuring the effective diameter of molecules of gases. Equations for these terms as given by MacDougall and experiments were performed and the data applied to the equation.

A Quantitative Chemical Examination of Surface Well Water from the Three Principal Geological Divisions of Denton County

Description: 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 Rate of Natural Fermentation of Various Solutions with Regard to Temperature

Description: 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.

Determination of Nitrogen, Phosphorus, and Potassium in Various Plants

Description: This study attempted to form some conception, through the analysis of a representative group of plants in the vicinity of Denton, of the amount of the three essential elements in the leaves as compared with the amount in the woody portions. The comparison of leaf with stem as to the quantity of nitrogen, phosphorus, and potassium is explained.

A Chemical Analysis of the Soils of Denton County, Texas

Description: 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.

An Experimental Study of the Electrodeposition of Lead

Description: 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.
