Physical chemistry

Chemistry is a branch of science that deals with the identification of the substances of which matter is composed. It also involves the properties and the ways in which they interact, combine, and change. Chemistry is important to life. The environment is composed of many chemicals without identification of chemicals we wouldn’t know what chemicals are safe to have around or which chemicals are harmful and dangerous to our bodies. To answer the enduring question, how do we gain knowledge to understand a chemical system, particularly since we cannot see atoms or molecules? We gain knowledge on this by the reaction the atoms or molecules going through from testing different valuable like the reaction of the molecules; how fast or slow they are moving we can use three factors: concentration, temperature and a…

Year 10 Physical Chemistry Assignment By Marcus Rivera 1) Combustible Energy a)Combustible energy is energy which relies on fuel to make energy. Combustible energy ignites to produce heat which creates energy, this is our main current state of energy which we use day to day. Some advantages to combustible energy is that if you use it as energy it’s very powerful, it’s very easy to combust and it is an abundant energy source. Some disadvantages of combustible energy is…

In this study, multiwalled carbon nanotubes@poly(p-phenylenediamine)-prussian blue (MWCNTs@PpPD-PB) nanocomposites were synthesized and used for the nonenzymatic electrochemical detection of hydrogen peroxide (H2O2). The PpPD layer also helps the MWCNTs to be dispersed in the water together with the PB formation and fixing on the surface of the MWCNTs. Moreover, PpPD, a conductive polymer, increases the electronic conductivity and stability of MWCNTs. By combining the selectivity and catalytic…

Chemistry is a world many of us forget exist in our daily lives. We go about our routines, forgetting that chemistry plays a key role in our lives. As a skier, I noticed the unseen world of chemistry when I am preparing for ski races, waxing my skis. Preparing my skis for a race weekend requires applying multiple layers of wax to my skis. The wax we use is commonly a fluorocarbon mixture. In order for the wax to be saturated into the ski, the block must be melted with an iron. Once the…

What is a chemist? A chemist is a scientist that studies, physical and chemical properties of different forms of matter. There are two profound chemist whose findings were crucial to today's understanding of chemistry. There names were Marie Curie and Dimitri Mendeleev, both chemist made significant impacts on modern day science and society. Dmitri Mendeleev is responsible for the creation of the periodic table, while Marie Curie is responsible for discovering radioactivity, which advanced the…

Pursuing a career in the chemistry field has been one of my dreams ever since I fell in love with the subject in high school. I love the challenge, knowledge, and determination that is required to obtain a chemistry degree; and the formulas and statistics it involves. There are different types of jobs in the chemistry field, but I decided I want to become an organic chemist researcher. The duties a chemist typically follows are research projects, testing and analyzing components, writing…

Introduction Chemistry is one of the broadest scientific subjects that are primarily focused on the manner in which matter interacts with energy. However, chemistry tends to be more focused on the study of the properties of matter as well as the interaction between various types of matter. The interaction is often facilitated by the reactions that involve either electron loss or electron gain, as described by the American Chemical Society (2014). Unlike other sciences, such as physics, chemistry…

My desire is to become an experimental physical chemist who studies biological systems. I hope to combine my interest in physical chemistry, and the knowledge I have gained working in a chemical biology research laboratory, to understand biological macromolecules at a fundamental level. When I first attended organic chemistry seminars as a sophomore, I was impressed at the eloquence and the enthusiasm of the speakers. Endeavoring to have insights like those of experienced scientists, I took…

I. PURPOSE The purpose of this lab was to observe the physical properties of different samples of matter and to use your observations and knowledge of chemistry to classify each sample as an element, a compound or a mixture. II. MATERIALS 10 beakers containing different samples of matter III. PROCEDURE First off, put on a laboratory apron. Then, take a few minutes at each lab station and record three physical property observations of each sample of matter. Record the three physical property…

Alchemy was the earliest understanding of today’s chemistry. These two display Is Alchemy Chemistry? different pathways of thinking and rationalising rather than two diverse concepts. The practice of alchemy is the basis of chemistry, as it was a vital role of origin and evolution towards chemistry we know today. The comprehension of both alchemy and chemistry will aid in order to establish their connections and difference of opinion or belief. Discovering both histories of the two concepts will…
