Unsolved problems in chemistry tend to be questions of the kind "Can we make X chemical compound?"‚ "Can we analyse it?"‚ "Can we purify it?" and are commonly solved rather quickly‚ but may just as well require considerable efforts to be solved. However‚ there are also some questions with deeper implications. This article tends to deal with the areas that are the center of new scientific research in chemistry. Problems in chemistry are considered unsolved when an expert in the field considers it

What chemistry means to me and how it impacts upon my life From the foods we eat and the medicines we take to the products we regularly use‚ our lives are inextricably linked to chemicals and their operating principles. Chemistry is everywhere. The air we breathe‚ the ground we stand on‚ the seas we sail‚ and the variety of living things including our own bodies; all these are made of substances that we call chemicals. These chemicals interact with one another‚ and‚ in many cases‚ these interactions

Chemistry In Our Daily Life Chemistry is a big part of your everyday life. You find chemistry in daily life in the foods you eat‚ the air you breathe‚ your soap‚ your emotions and literally every object you can see or touch. We live in a world of matter. From the food that sustains our lives to various objects that have built up our physical culture‚ everything is made up of matter. The human body itself is a mixture of matter of differing types. The humans who used materials obtained from nature

Food Chemistry What is food chemistry? Food chemistry is the application of the actual science that goes into the production‚ development‚ and actual creation of the foods we frequently consume. In reality‚ much more thought as well as actual science goes into the food production and consumption that we as a society divulge in so regularly. It is up to the food chemists to design the most efficient and fastest way to make and preserve both the appeal as well as the nutrition of the food. With

Lab Report Marisa McKinney P. 2 Purpose: To investigate the periodic variation of density in Group 4A elements. Background: When the elements are arranged in order of increasing atomic number‚ they exhibit periodic recurrence of properties. Elements in the same group in the periodic table tend to have similar physical and chemical properties. These similarities are due‚ in large part‚ to similarities among the electron configurations of the elements in a group. You can find periodic
