Lab Report 1708 Mrs. Himler Ryan Nelson 9/20/2024. Lab Report INTRODUCTION: During this lab‚ the group used 3 food thickeners. These thickeners are used to thicken‚ stabilize‚ and prevent separation for our daily products such as ranch‚ ice cream‚ and other dairy products. The group used modified food starch‚ corn starch‚ and guar gum. They all are different from each other‚ each in a unique way. Firstly‚ guar gum is like pectin‚ a soluble fiber and polysaccharide. Furthermore‚ the body cannot digest

Abstract The primary focus of this lab was on microscopy and simple stains. Crystal violet and Carbol fuchsine‚ simple staining components‚ were used to stain the slide in order to see the different microbes in order to determine their cellular shape and identify unknown ones by comparing. Introduction Bacterial cells are usually colorless because cytoplasm‚ for the most part‚ is transparent. Since the bacteria are colorless‚ it is almost essential to add a stain to make the bacteria more visible

The main purpose of this lab is to explain what emulsifiers and emulsions are and how emulsifiers affect emulsion stability. An emulsion is a mix of to or more liquids that usually do not mix together. One liquid is evenly dispersed in small droplets throughout the other liquid. Many emulsions contain water as one of the phases. There are two different types of emulsions. One type of emulsion contains oil droplets that are dispersed within water. It is considered oil in water emulsion. The other

Shavonna Bailey Barbara Transue English 102A MW 6:30 – 8:40 pm Alchemy The alchemy lab proposed that Alchemy is a craft. The law is that in order to create something new‚ it must die first. You cant be reborn without dying first. This "becoming" is how they explain alchemy. Its process can also be expressed by the traditional formulas of initiation: the suffering‚ death‚ and resurrection of the god or the neophyte‚ represented by the substances in the crucible or by the material of the craftsman

Lab Report for Chemical Changes and Conservation of Mass Lab Previous to the reaction‚ the magnesium appeared to be a solid‚ white‚ black‚ and grey substance with many small dark particles within the substance. The hydrochloric acid was a clear liquid that looked like water It weighed 42.2 grams in total. During the reaction‚ the two substances produced bubbles‚ creating smoke and became warm with a smell that is irritating to the human nose. After the reaction‚ it appeared to be a clear‚ bubbly

EXPERIMENTAL PROCEDURE: 1. 2.07 g of the mixture of naphthalene and benzoic acid was weighed accurately on a balance. The mixture was then dissolved in 40 ml dichloromethane and the solution was poured into a separatory funnel. 2. 20 ml of aqueous sodium bicarbonate solution was added to the dichloromethane. A stopper was placed on the separatory funnel and was shaken and pressure was frequently released. The 2 liquids separated into clear layers and the lower layer (dichloromethane layer) was

The purpose of this lab was to separate and purify a compound. This was achieved using techniques that allowed the extraction of the acid‚ the isolation of the neutral compound and the melting point classification of the neutral compound to test the purity of the sample. Chemical Reactions: HA + OH- A- + H2O R-COOH + OH- R-COO- + H2O Organic Acid Insoluble in H2O Conjugate base Soluble in H2O Procedure: A 0.170g sample consisting of a mixture of 0.110g of an unknown

Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules

The Need for a Separation Between Government and Religion As Benjamin Franklin (One of the founding fathers) once said‚ “When a religion is good‚ I conceive it will support itself; and when it does not support itself so that its professors are obliged to call for the help of the civil power‚ ‘tis a sign‚ I apprehend‚ of it’s being a bad one” (Nord 134). The separation between religion and government‚ also known as “the separation of church and state” has been a controversial topic‚ and has progressively
