Role of Chemistry in Every day Life Chemistry has played a key role in determining the nature of the modern world. In reality chemistry is much interesting for both study and practice. While defining chemistry let us consider a traditional definition which states ’Chemistry is the science of matter which undergoes changes during chemical reaction’. But in reality chemistry goes beyond its traditional definitions. From the evolution of mankind itself‚ chemistry had a close connection with the daily

Emission Spectra & Flame Tests Intro The emission spectrum is used in modern chemistry to help further studies of wavelengths and the spectrum. When a metal in a compound reacts in a flame and produces a color‚ it helps to show the strongest color in the emission spectrum. The purpose of performing these operations on the flame was to see how different metals would react. Using a spectroscope‚ it is possible to observe the line emission spectrum produced by sunlight‚ artificial light‚ and

Laboratory Report: Flame Colors of Metals Abstract The experiment about flame color of metals demonstrates how electrons jump into their excitedstate from their ground state as it came in contact with heat. As it return to its lower energy state‚it emits the absorbed energy in the form of light. A platinum or nichrome wire was dipped into aconcentrated HCL and was heated to clean it. The wire was dipped into different salt solutionsand heated in order to determine the metallic ion’s color and wavelength

Examples of Hypothesis A hypothesis- is an educated guess or proposition that attempts to explain a set of facts or natural phenomenon. It is used mostly in the field of science‚ where the scientific method is used to test it. Testing Hypothesis vs. Tested Hypothesis -An hypothesis can be testing a concept or it can be developed as a result of study:A testing hypothesis is one that can be tested‚ meaning you can measure both what is being done (variables) and the outcome.A tested hypothesis is
