This document summarizes research on measuring nitrogen permeance through ceramic zeolite membranes in the presence of other gases like methane, isobutane, and isobutene. The key findings are:
1) Nitrogen selectivity is highest at low temperatures and is not significantly affected by feed pressure or nitrogen concentration for nitrogen/methane mixtures.
2) Nitrogen permeance decreases when isobutane or isobutene are present due to concentration polarization near the membrane surface and external adsorption of these gases on zeolite crystals.
3) The decrease in nitrogen permeance is greater for isobutene mixtures since isobutene adsorbs more strongly to zeolites than

This experiment aimed to synthesize benzaldehyde through catalytic oxidation of benzyl alcohol using manganese oxide. Manganese oxide was first synthesized by oxidizing potassium permanganate and ferrocene in sulfuric acid. Benzyl alcohol, toluene, and manganese oxide were then heated to perform the catalytic oxidation. X-ray diffraction testing found the manganese oxide was in an amorphous phase. Gas chromatography was used to analyze the products and found the amorphous phase manganese oxide had higher conversion of benzyl alcohol to benzaldehyde than the gamma phase. In conclusion, the experiment successfully synthesized benzaldehyde through catalytic oxidation using manganese oxide as hypothesized.
Separation, analysis etc good
Sea water contains various dissolved ions that allow it to be used for industrial processes through electrolysis. Electrolysis of sea water involves passing electricity through it, breaking down water into hydrogen and oxygen gases and producing chlorine gas, hydrogen gas, and sodium hydroxide solution. The salt industry utilizes these products from sea water electrolysis in various ways, such as manufacturing chlorine for bleaches and hydrochloric acid for ammonia production.
Classification of dyes
Dyes can be classified as either natural or synthetic. Natural dyes come from plants and animals while synthetic dyes include water soluble dyes like direct, acid, basic and reactive dyes as well as water insoluble dyes like vat, sulphur and disperse dyes. Synthetic dyes are further broken down by their chemical structure and properties.
Presentation
This document describes an experiment to synthesize benzaldehyde through the catalytic oxidation of benzyl alcohol using manganese oxide.
Potassium permanganate, sulfuric acid, and ferrocene were used to synthesize manganese (IV) oxide, which was then tested through x-ray diffraction and found to be in an amorphous phase.
Benzyl alcohol, toluene, and the synthesized manganese oxide were heated in a round bottom flask with a condenser. Gas chromatography analysis found peaks indicating the presence of benzaldehyde, showing the reaction was successful in synthesizing the desired product. Further tests found the amorphous phase manganese oxide performed with higher conversion than the gamma phase.

This document provides information on various chemistry experiments and techniques. It discusses experiments on rates of reaction and factors that affect rates. Methods for separating mixtures like filtration, crystallization, distillation and chromatography are described. Tests for identifying cations and anions are outlined. Procedures for preparing and collecting gases in the laboratory are also summarized.
Lab Report
The document summarizes a lab report on observing physical and chemical changes. The lab involved experiments with copper chloride, magnesium, hydrochloric acid, barium chloride, glass, and sodium bicarbonate. Key results included copper chloride turning blue when stirred in water, magnesium burning brightly and leaving ash, and reactions between acids and bases producing gases. The conclusion distinguished physical changes that alter a substance's form from chemical changes that produce new substances through chemical reactions.

The document summarizes an experiment on the preparation and properties of acetylene gas. Key points:
1. Acetylene gas is prepared by the hydrolysis of calcium carbide with water. It is a colorless gas with a garlic-like odor.
2. Acetylene's properties include burning with a luminous yellow flame, reacting slowly with bromine and permanganate solutions, and forming precipitates with silver nitrate and copper chloride solutions.
3. The experiment allowed students to observe acetylene's preparation, combustion, halogenation, oxidation, and substitution reactions. It provided insights applicable to laboratory analysis of body fluids and blood samples.

Thy womb review
The document discusses the Badjao ethnic group who dwell in the Sulu archipelago in Mindanao. Some Badjao live in small wooden boats while others have stilt houses over the water or live on land. They fish and the women weave colorful mats. The government should support ethnic groups by tracking their populations, providing housing and jobs, and using local languages in schools. The movie "Thy Womb" aims to showcase Badjao culture and showcase the richness of Philippine cultures to promote Filipino pride. It explores their traditions like weddings and lifestyle living on the water through beautiful cinematography.

This document summarizes research on the enterovirus strain EV-D68 and its ability to cause respiratory illness in children. The key points are:
1) EV-D68 typically causes mild cold symptoms but in some cases can lead to wheezing and difficulty breathing as it affects the lower respiratory tract.
2) Studies are being conducted to understand why this strain may be causing more severe illness and if there are any genetic differences from past strains.
3) While most children recover on their own, those with underlying conditions like asthma are at higher risk and parents should seek medical care if their child's breathing becomes labored.
