perfect than gold‚ it was reasonable to believe that nature created gold out of other metals found deep within the earth and that a skilled artisan could duplicate this process. It was said that once someone was able to change‚ or transmute a "base" chemical into the perfect metal‚ gold‚ they would have achieved eternal life and salvation. In this way‚ alchemy turned into not only a scientific quest‚ but a spiritual quest as well. Although the purposes and techniques were often times ritualistic and

What happens if an atom of an element gains or loses electrons? What happens if an atom of an element gains or loses neutrons? What happens if an atom of an element gains or loses protons? Atoms in which the number of

words‚ each element has a unique number that identifies how many protons are in one atom of that element. For example‚ all hydrogen atoms‚ and only hydrogen atoms‚ contain one proton and have an atomic number of 1. All carbon atoms‚ and only carbon atoms‚ contain six protons and have an atomic number of 6. Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic number of an element never changes‚ meaning that the number of protons in the nucleus of every atom in an element is always

Chemical Reactions Lab Synthesis Reactions: Synthesis reactions occur when two elements or compounds combine to create one single compound. The general equation of synthesis reactions is: A+B→AB. The following are the complete balanced equations for the five synthesis reactions performed in the lab. Reaction 1: Reaction 2: Reaction 3: Reaction 4: Reaction 5: The reaction of CO2 and water is a prime example of a synthesis reaction. This is a synthesis reaction because it follows the general

This image is Dalton’s table of elements and the number of elemental combinations described in his 1808 publication ‘New System of Chemical Philosophy’. It also shows the molecular of formula of known gases. His theory is all matter is made of atoms and unchangeable and indestructible. Also all atoms are given an element are identical in mass and properties. The theory continued; he believed that a chemical reaction was rearranged atoms and that compounds

Then he talks about a pathologically shy‚ absentminded‚ stuffy‚ women-hating chemist. This man did make some discoveries about inflammable gas and proved water to be an oxide.

Physical and Chemical Properties Purpose: The Physical and Chemical Properties lab provides the opportunity to investigate the physical and chemical properties of pure chemical substances and analyze the experiment results. Procedure: In the beginning of the experiment‚ I filled two 24-well plates half way with the given chemicals and sucked up these chemicals into their labeled pipets for later use. Following this‚ I performed a number of steps on each of the four test tubes and recorded observations
