BIODEGRADABLE SUBSTANCES Biodegradable matter is generally organic materials such as plant and animal matter and other substances originating from living organisms‚ or artificial materials that are similar enough to plant and animal matter to be put to use by microorganisms. Some microorganisms have a naturally occurring‚ microbial catabolic diversity to degrade‚ transform or accumulate a huge range of compounds including hydrocarbons (e.g. oil)‚ polychlorinated biphenyls (PCBs)‚ polyaromatic

Liquids & Solids Pre Lab Questions: 3pts 1. What are the learning goals of this lab? The learning goal of this experiment is to view and experience the melting point and boiling point of different substances. 2. Why is acetamide not allowed in contact with your skin? What precautions does one have to take to work with this chemical? Acetamide is a carcinogen‚ which can cause cancer. Therefore‚ it should not be allowed to come in contact with a person’s skin. Any person working with this chemical

Date of Experiment October 7‚ 2012 Report Submitted: October 7‚ 2012 Title: Liquids and Solids Purpose: The purpose of this experiment is to determine the boiling point of liquids and the melting point of solids. Procedure: I got all of my materials together and set up. I poured rubbing alcohol in a beaker and rubber banded it with the thermometer. I logged the last bubble that came out of the capillary tubes. After that I crushed the acetamide and carefully put it in the capillary tube

Allison Oneal Chemistry I June 20‚ 2013 Dr. Michael May Properties of Gases I. Abstract The purpose of this experiment is to examine the properties of several gasses‚ which were the products of a reaction‚ and examine the way the gasses react under certain conditions. These conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Experiment Before I began the experiment I gathered all my supplies from the given list in the lab manual.

Non-biodegradable waste will NOT break down (or won’t for many many years). Examples are plastics‚ metal and glass. Some dangerous chemicals and toxins are also non-biodegradable‚ as are plastic grocery bags‚ Styrofoam (polystyrene)‚ and other similar materials but will eventually break down over time.

Free Recycling Waste Philippines
Turning biodegradable waste such as food scraps and yard trimmings into compost or recycling them through your local yard waste collection facility‚ eliminates a large portion of any household or business’s waste stream. However‚ the bulk of waste does not biodegrade quickly or ever. By thinking ahead‚ you can reduce your waste generation and reuse packaging rather than throwing it away. Consider Packaging When buying food or consumer goods‚ the U.S. Environmental Protection Agency recommends you

Is glass a solid or a liquid "The idea that glass is a fluid is a very widespread myth." (Yvonne Stokes:1999‚Discover Magazine) This myth has survived for centuries because glass is such a confusing matter which cannot be compared to the three ordinary kinds of matter described in our particle theory of matter. Gasses contain free flowing molecules which are much further apart then liquids and gasses which removes the possibility of glass being a gas. A liquid however contains tighter bound molecules

Objective:- The aim of this experiment was to find the molar mass of unknown volatile liquid under known temperature and pressure. Introduction Molar mass or gram molar mass is the mass of the substance under consideration without distinguishing whether a substance is an element ‚ a molecule or an ionic compound. These elements‚ molecules or ionic compound could be solid gas or liquid. The molar mass of gas or vapor could be measured if the gases obey the law of Ideal Gas . The mass of
