The Population Size of Multiple Microorganisms in Aerobic Compost Alison Pagano‚ Lauren Sammaritano Biology IV- Ecology 4-11-13 Abstract. The experiment provided evidence of microorganisms in aerobic compost. 18 buckets were set up with three different trials of compost‚ wet‚ dry‚ and moist. Although microorganisms were present they were too small to be identified and also conditions in the experiment were not stable enough to maintain life. Due to this we were not able to make

Introduction Percentage composition is the percentage of a formula mass represented by each element. Percentage composition compares the mass of one part of a substance to the mass of the whole. The law of definite proportions states that a specific compound always contains the same amount of elements in fixed proportions by mass. By finding the percent composition of magnesium oxide one will essentially be proving this law to be true. Purpose The purpose of this lab is to determine the percent composition

Environment ’s effect on Growth of Bread Molds I. INTRODUCTION A. BACKGROUND OF THE STUDY Molds are species of fungi. There are many different kinds of molds‚ some of which are specially adapted to grow in particular environments or on particular surfaces. Unlike plants‚ molds cannot produce their own food‚ so they need an external source of energy and nutrients. Molds (and mildew) are fungi. Fungi are neither plant nor animal but‚ since 1969‚ have their own kingdom. The fungi kingdom

A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically combined. All of these techniques involve changes in the physical state of a chemical compound rather than chemical changes. Sea sand‚ table salt‚ and two other unknown substances will be separated using the separation techniques in order to demonstrate the properties of mixtures and their ability to be separated by physical means. If we use

The process of naming compounds allows chemists to communicate formulae in words rather than in chemical symbols. There are‚ however‚ a few rules about naming compounds which need to be known in order to write a formula in word form or translate a compound in word form into chemical symbols. Ionic compounds If the compound is ionic‚ then the name of the cation (usually metal) comes first‚ followed by the ’compound’ name of the anion. To find the compound name of an anion‚ replace the end of the

Identifying Organic Compounds Problem: Based on the color of the indicator‚ which type of organic compound will be found in each type of food? Hypothesis: If Benedict solution is added to honey‚ then it will turn. If Biuret solution is added to egg whites‚ then it will turn. If Benedict solution is added to corn oil‚ then it will turn. If Benedict solution is added to glucose‚ then it will turn. If Benedict solution is added to gelatin‚ then it will turn. If Benedict solution is added to butter

Separating a Mixture of Compounds Exp. No. 2 name Chemistry 145 February 2‚ 2014 I. Purpose The purpose of this experiment was to separate this mixture into components‚ determine the mass and percentage of each component. In addition to test the accuracy of an alternative method of subtraction to find the mass of the sodium chloride directly. Start with a mixture of sand (SiO2)‚ sodium chloride (NaCl)‚ and ammonium chloride (NH4Cl)‚ and use these separation processes: sublimation filtration
