Mass Production During the 1920’s‚ the United States industries and large businesses prospered greatly. Companies began to manufacture large quantities of their products using machines and a process known as the assembly line. This knew method was known as mass production. Mass production opened up many jobs for all types of people. For the first time women‚ immigrants‚ and African Americans were accepted into the work force. This time period marked a major change for women. It was found that more

What is molar mass?Molar mass is the weight of one mole (or 6.02 x 1023 molecules) of any chemical compounds. Molar masses of common chemical compounds that you might find in the chemistry laboratory can range between 18 grams/mole for compounds like water to hundreds of grams per mole for more complex chemical compounds.The lightest possible chemical that one can have under normal conditions is hydrogen gas‚ or H2. There is no limit to how heavy a chemical compound can be - it is not uncommon for macromolecules (large

Module 2 Mass Spectroscopy [pic] [pic] Diagram of a mass spectrometer Stage 1: Ionisation The sample is injected as a vapour and the atoms are bombarded by fast moving electrons. This causes the molecule to fragment into two or more pieces. When a molecule or part thereof fragments‚ one portion would be positively charged while the second portion will be uncharged. All uncharged fragments are ultimately lost in the machine as mass spectrometers only work with positive ions. Stage 2: Acceleration

The Atomic Mass of Metallo You may have noticed on the periodic table that the atomic mass of an element is usually not a whole number. That happens because of isotopes. An atom that is missing a neutron or has an extra neutron is called an isotope. They are still the same element; however‚ they are just a little different from every other atom of the same element. Most of the carbon atoms in the universe are Carbon-12‚ with 6 neutrons. A small percentage of carbon atoms are Carbon-13‚ with 7 neutrons

The hydrochloric acid was a clear liquid that looked like water It weighed 42.2 grams in total. During the reaction‚ the two substances produced bubbles‚ creating smoke and became warm with a smell that is irritating to the human nose. After the reaction‚ it appeared to be a clear‚ bubbly
