Law of Conservation of Mass Experiment CER Question: Does a controlled (closed system) zip lock bag experiment demonstrate the Law of Conservation of Mass? Claim In our class we did an experiment where we put different known supstances into a ziplock bag and closed the bag, that way we could achieve a closed experiment and attemp to support The Law of Conservation of Mass. The Law of Conservation of Mass states that mass can neither be created nor destroyed in a closed system. According to my data

The purpose of The Law of Conservation of Mass Lab in class was to conduct an experiment (by combining acetic acid and baking soda) to prove that in any chemical reaction, the total mass of the reactants and the total mass of the products are equal. In our experiment there was nothing that would indicate a chemical reaction other than the formation of gas. When the baking soda fell into the acid (in both trials), bubbles were created and the balloon that was on the flask filled with gas. This formation

ADI Lab Investigation - Law of Conservation of Mass The Law of Conservation of Mass states that mass is neither created nor destroyed. The law also states, that the mass of the reactants are equal to the mass of the products in a chemical reaction. Matter is composed of atoms, and atoms can be bonded to form different types of molecules. In a chemical reaction, no new atoms are created, and no atoms are destroyed. Also, in a chemical reaction, bonds between atoms in the reactants are broken, and

David Hamby Miss.Gregory World History 28 November 2017 Antoine-Laurent Lavoisier was born August 26, 1743 he was a French chemist and the leading figure in the 18th century chemical revolution who developed an experimentally based theory of the chemical reactivity of oxygen and co authored the modern system for naming chemical substances. Having also served as a leading financier and public administrator Before the French Revolution. Lavoisier was the first child and only son of a wealthy

Antoine Lavoisier, founder of the oxygen theory of combustion, leader of 18th century chemistry, and published author of “Elementary Treatise of Chemistry”. Born in Paris, France on August 26th, 1743, Antoine Lavoisier was born as the only son into a wealthy bourgeois family. In his young life, he showed an abnormal amount of public concern and studiousness. He was introduce to Collège Mazarins’ studies and sciences, and soon after went to study law. Due to the lacking demands of the students at

There is also taxes on ammunition and firearms which also benefit the cause, annually millions of dollars are dispersed to State conservation efforts and wildlife management programs. Without funding from these purchases many of the active programs that protect millions of wild animals and habitats would not be able to

Keeping Wild-Caught Animals is Inhumane Many wild animals are taken into people’s homes every day. Wild animals are causing harm to people in their homes. Some people argue that animal attacks are caused by the owners rather than the animal itself. Wild caught animals need to be taken out of people’s homes, and put in places fit for the animal. Keeping wild caught animals is unsafe. According to the article, “Keeping Wild Caught Animals - Unsafe, Illegal, Inhumane”, it is very dangerous to own

the Montana Wetland Council (MWC), led by DEQ, has developed statewide framework, Priceless Resources: A Strategic Framework for Wetland and Riparian Area Conservation and Restoration in Montana 2013–2017. This framework, which builds on the prior framework, Priceless Resources: Strategic Framework for Wetland and Riparian Area Conservation and Restoration in Montana 2008–2012, provides a focused approach to protecting MT’s wetland

Is recycled water really safe to use and drink? Environmental Engineering 3/9/2015 [Type the company name] Satellite   A clean water is very essential not just with the environment but most especially among humans. It is important for us to know if the water we drink is clean and safe to drink because we are pertaining to our health. If we drink contaminated water, we are drinking the risk of having bacteria and viruses into our body so it is essential for us to know how safe the water we are

the lower position. It also depends on a certain level, energy will changes while throwing an object up and down. Students will also learn about the principle of the physics, which are the law of conservation of energy. Energy cannot destroy or create; students can change one type to another type of mass to force. One of the most important energy students will learn about potential energy, kinetic energy, and elastic potential energy. Kinetic energy is energy that can be transforming into different

requirements and behaviors of various species, observing the dangers they encounter, and suggesting potential safeguards. In addition, advocacy writing, in which members of the wildlife protection community craft persuasive statements to support conservation efforts and impact policy choices, remains an important rhetorical situation. To gain support for their cause, they employ specific rhetorical techniques like visceral pleas, first-person narratives, and logical arguments based on statistics. In

a calorimeter. The goal of this experiment is to modify the calorimeter and to improve the energy capture from the combustion of the chips. Kinetic, Potential, and Law of Conservation energies are all used in our everyday life. Energy is neither created nor destroyed, though it can be transformed, which is the Law of Conservation of Energy (Castro). Kinetic Energy can be calculated by E = ½mv2 (Lucas). There are different types of potential energies too. “Gravitational potential energy is the energy

some scientist are wondering if bringing animals back to life is the right way to save the Earth’s endangered species. Reintroducing extinct animals could hurt today's ecosystems, lead to unforeseen consequences, and promote disregard to the current mass extinction problem. Many experts

Attention Getter: Have you ever read a story about animals attacking and eating humans? Transition statement: Well, That is what happens in this scary story… Background Information: It is the beginning of the winter and the birds are starting to act a little strange. They soon realize that tens of thousands of birds started to attack and eat people for no apparent reason. Whoever has the better survival skills will outsmart the birds and stay safe. Topic: In the story

Mass is anything that takes up space. Mass is made up of small subatomic particles called atoms. Atoms have three main parts electrons, protons, and neutrons. The mass of the atom is found in the nucleus. The Law of Conservation of Mass states that mass cannot be created nor destroyed, and that the mass of the reactants will be equal to the mass of the products. This means that no matter what, the mass of the reactants when mixed together should be equal to their original masses. A chemical reaction

Background: In this lab we used conservation of momentum, conservation of energy, and pendulums to complete the lab. Momentum is always conserved in collisions regardless of whether or not kinetic energy is conserved. The law of conservation of momentum states that momentum is always conserved in a collision (Mr. Patterson’s Class). The law of conservation of energy states that energy can not be created or

Background The law of conservation of energy is energy that can be transferred from one object to another. Energy cannot be destroyed nor created therefore; it can be changed from one form of energy to another type of energy. It signifies that energy might be passed on or wasted, but it can never be lost. In addition, if an object has wasted its energy, it is always gained by another object, commonly heat. The kinetic theory of matter is that substances are comprised of a large number of small

I. Title: Mass and Mole Relationships in a Chemical Reaction II. Background: Percent yield is the ratio of actual yield to theoretical yield. Amount in percent of one product formed in chemical reaction. Actual yield is the information found is experiments or is given. It is also the real amount. Theoretical yield is found through a mathematical equation. The amount produced is another way of identifying theoretical yield. The limiting reactant is the reactant that is completely used in the reaction

Bringing in billions of dollars every year, promptly following illegal drugs, firearms, and human trafficking, animal poaching is the prohibited act of slaughtering, capturing, and trading animals. Due to the approximated tens of millions of animals being poached for their fur, shells, horns, etcetera, there is a rapid decline in population, causing a multitude of species to confront endangerment and possible extinction. Furthermore, some of the most at risk animals include, but are not limited to

The question is, how does a physical or chemical change affect the mass of a substance within a closed system? To respond to this question, my group did a lab to determine whether or not the mass would change or not. Our lab was to have a plastic bag containing baking soda, then add a cup of vinegar and a block of clay to the mix. We made sure to weight every element separately and then add them up for our total mass of 31 grams before the reaction. During the reaction, as soon as the vinegar was
