Conservation of mass

The Law of Conservation of Mass is a system where an isolated system cannot be created or destroyed by a chemical reaction or physical transforms. (from the website: https://courses.lumenlearning.com/introchem/chapter/the-law-of-conservation-of-mass/).The Law states that mass of products in the reaction must be equal to the reactans or the things that causes the reactants.Again from the same website.The History behind it is that the Greeks were the first to come up with the idea,but it wasn’t made by them.That came from Antoine Lavoiser.He described the law as a “fundemental prinicple of physics” in 1789.This was from the same website.The law was later then amended by Albert Einstien which he described the total energy in a system remains a…

Law of Conservation of Mass Have you ever wondered why certain things decompose faster than others? I was interest in doing this project because I’ve always wondered why certain things decompose faster than others, and why they decompose. For my science fair project I want to find out why what types of decomposition there are, and how the process of decomposition works. I like to observe the tiny things in life, and why it works, or why it happens, and I feel like I could gain some knowledge on…

oxide using the Law of Conservation of Mass. This states that in measuring the mass of each component of copper oxide and determining the percent composition of each the copper and the oxygen within copper oxide it is possible to find the ratio of the elements within the compound. Procedure: In order to conduct this lab, 25.1mL of distilled water then 25.5mL of 3M HCl must be added 2.11g of copper oxide. This solution must be stirred until it’s dissolved then continuing for stirring until the…

“The Law of Conservation of Mass states that matter can be changed from one form into another, mixtures can be separated or made, and pure substances can be decomposed, but the total amount of mass remains constant.” (University Of Wisconsin) The data the was found from our lab shows that the data is not consistent to the Law of Conservation of Mass because our results showed an increase in mass. To start the lab, .7 grams of copper was measured out and at the end, the total amount of copper was…

This practical experiment is based is based on the theory of Law of Conservation of Mass stated by Antoine Lavoisier. Antoine Lavoisier was a French nobleman who had a major influence on the history of chemistry and biology. Today he is considered to be the “father of modern chemistry.” In all his experiment he supported the Law of Conservation of Mass. Antoine stated this in his theory, “The law of conservation of mass states that mass can neither be created nor destroyed in a chemical…

The purpose of this observation is to prove if the concept of conservation is different for age groups of children described in the textbook Infants and Children by Laura Berk. Background Information I am observing my subject in the cognitive domain and will be focusing on conservation. The theorist that studied conservation is named Piaget. Piaget is a theorist that studies children development. Piaget believed that children are explores and needs to explore their surroundings by…

According to Piaget’s theory in child development, conservation is the understanding that something stays the same in quantity even though its appearance changes. To be more technical, conservation is the ability to understand that redistributing material does not affect its mass, number, volume or length. In cognitive psychology, the principle that properties of substance such as weight and mass remain the same (are conserved) when superficial characteristics such as their shapes or arrangement…

themselves from anything that get in their way. Most important, a game warden must have good prior experience with fishing, hunting and boating because it becomes very beneficial. There are 5 different divisions throughout the South Carolina Department of Natural Resources are they go as follows, land, water, conservation division, law enforcement division, marine resource division, outreach and support services division, and finally last but not least, wildlife and freshwater…

The Great Smoky Mountains, belonged to the Paleo Indians, which then was used by loggers and Civilian Conservation Corps in the year of 1800. The park’s great stretches even farther back, thus, having more valuation to the people now who own the park. A projectile point has been found was estimated to be 9,000 years old. The living, and non-living things that are native to the land, have a special meaning to this park, because of, their history in the park as well of human development in the…

Imagine being trapped in a cage and having to live based on someone else’s schedule. Well that is zoo animals feel every single day. Animal captivity has been around for hundreds of years. Animals were held as creatures of worship and used for gladiatorial contests. It wasn’t until the 1800s that public zoos became more common. As they became more common the focus on educational purposes became less and the animals began being treated abusively and being mishandled. Zoos should be shut down.…
