Chemical Change Research Paper

A chemical change is a change that alters the identity of a substance. A chemical change can be identified by five things: change in mass, formation of a precipitate, release of heat and/or light, color change, or giving off gas.

Hypothesis: If we use these materials and use magnets, water, burners, and filters on the mixtures and elements given we should determine what kind of effect these materials given will have on these mixtures and elements, physical or chemical.

A physical change is one that affects only the physical properties of a substance, while a chemical change alters a substance at the molecular level.

Purpose: The purpose of this experiment is to observe a variety of chemical reactions and to identify patterns in the conversion of reactants into products.

A physical change includes a change in the material without affecting its composition, such as the physical state change. However, a chemical change includes the change in the composition of the substance. The change in color, formation of a gas or a solid product, and the production of energy are the evidences of a chemical reaction, thus, of a chemical change.

This would be a physical change because for it to be a chemical change the product would have to be a new

The students are introduced to the purpose and structure at the beginning of the course. The learners were introduced to the purpose and structure of the course in the course syllabus, in the orientation, and in the CHM 1025-Introductory Chemistry video. The course description in the syllabus clearly describes the purpose for this course.

Chemical Changes: Water to Carbonated water, it could impact on the environment because if extra carbon dioxide gets out of the Coca Cola it could increase the effect of Greenhouse gas and Greenhouse gas could impact global warming which is a BIG problem to the environment and Sunlight that’s coming from the Sun to Earth will escape into space. And also “Carbonated or Carbon” is Carbon Dioxide gas pressure so the water has carbon dioxide gas pressure in it to turn it into carbonated water. Another Chemical change is if you mixed the Coca Cola with something else it’s gonna change the Coca Cola and it’s gonna be mix with whatever you mixed it with. When you mix the Coca Cola, it changes the compound of the Coca Cola with turns the Coca Cola

Chemical changes happen on a molecular level when you have two or more molecules that interact. Chemical changes happen when atomic bonds are broken or created during chemical reactions. Anything that is burning is a chemical change. Or frying an egg is a chemical change cause it can not go back to wear it was before theres no fixing.

Chemical reactions make new things by rearranging other things. In a chemical reaction, the main change that occurs relates to the way atoms are bonded to each other, in order to change those connections, bonds must be broken and new bonds be formed.

This is a simple equation that doesn’t properly prove the reaction. It is very complex and starts with this:

An example of a chemical change that one could come into contact with daily is rust. Air and iron are the reactants in this situation while rust is the product. The chemical equation for this reaction would look roughly like this, O+FE= OFE or rust. This is clearly a chemical change because you cannot reverse it meaning you cannot take rust and pull out the iron to leave air or vise versa. All chemical changes are finite. One other example of a chemical change is the burning of any substance. For example if one were to burn a sheet of paper it would create ash. This chemical change is finite because you cannot change ash back into paper.

A chemical reaction is a process in which elements or compounds react with one another to create new or different substances. There are two parts to a reaction. Those two parts are the products and the reactants. The reactants are the chemicals or chemical compounds that are going through the reaction itself. The products are chemical elements or chemical compounds that are produced as a result of the reactant or reactants reacting. There are four key indications that there’s a chemical reaction is taking place. Those four signs include a change in color and/or odor, formation of a precipitate or a gas, the release or absorption of energy (light, heat, electricity), and if the reaction is irreversible. Along with this information, there are ways to predict the products of a reaction.

In our bodies we use fuel and energy from the foods that we eat to keep the body in motion. Digestion is considered a chemical change, because when you consume food and it goes through your digestive system, it turns from a solid to a liquid state. A chemical reaction occurs when the digestive process in the pancreatic acid dissolve the marinated foods then dissolves into a soapy liquid called chyme.

Chemistry is defined as, “the study of the composition, structure, and properties of matter, the processes that matter undergoes, and the energy changes that accompany these processes” (Davis 3). Chemistry has been around since the dawn of time, way before humans realized what chemistry was or its importance. The building blocks of the earth, such as minerals of the soil and atmospheric gases, all arise from chemical elements. Natural resources are all chemicals or chemical compounds, and the study of such resources is what began the Chemical Revolution of the 18th century. Today, chemists still toil away, attempting to understand the reactions of the universe. Chemistry is a timeless field of study, and will continue to be so long into
