Chemistry Matter Anything that occupies space Solids matter with definite weight, volume and shape Ice liquids matter with definite weight and volume but no definite shape Liquid Nitrogen liquid mercury Gases Matter with definite weight but indefinite volume and shape neon gas Gases in many forms..... Physical change a change in the physical characteristics of a substance without creating a new substance Chemical change change in a substance that creates a new substance The difference between the two http://www.youtube.com/watch?v=gCbqjs-pqJo Chemistry the scientific study of matter and the physical and chemical changes of matter Organic Chemistry deals with all matter that is now living or was alive at one time, with carbon present such as plants and animals inorganic chemistry studies all matter that is not alive, has never been alive and does not contain carbon, such as rocks, water and minerals Elements basic substances that cannot be broken down int simpler substances hydrogen gas atomic number 1 H Helium atomic number 2 gas He lithium atomic number 3 solid Li Carbon Atomic number 6 C solid Nitrogen Atomic number 7 gas N Oxygen Atomic number 8 gas O Aluminum Atomic number 13 solid Al Sulfur Atomic number 16 solid S Mercury Atomic number 80 liquid H Atomic Number http://www.youtube.com/watch?v=ufeZCeu_TS o Protons Nuetrons Electrons http://www.youtube.com/watch?v=Vi91qyjuknM Molecule two or more atoms joined by a chemical bond Molecule http://www.youtube.com/watch?v=qmgE0w6E6 ZI Chemical Bonds http://www.youtube.com/watch?v=_M9khs87x Q8 Amino Acids compound consisting of carbon, oxygen hydrogen and nitrogen. 22 common aminos Hair is a form of protein...Keratin 97% Keratin 3% trace minerals Peptide Bonds http://www.youtube.com/watch?v=va0DNJId_C M Polypeptide Bonds Backbone of all protien molecules When two amino acids are positioned end to end, the acide endo of one amino accid attaches to the amino end of another amino acid NO HAirdryer for Sodium hydroxide relaxer looses the characteristic of hair Side bonds Hydrogen salt disulfide vander Waal’s forces Hydrogen Bond http://www.youtube.com/watch?v=tv4Jrc06yLA Salt Bond result in attraction of unlike charges Disulfide Bond http://www.youtube.com/watch?v=O6eKuSbnO MA van der Waal’s Forces role in bonding protien chains experiment http://www.youtube.com/watch?v=5n7kBkBcXg o Page 117 Review Hair’s chemical structure Ph Potential Hydrogen ph explained http://www.youtube.com/watch?v=M8tTELZD5 Ek The scale Chemistry of Cosmetics solutions suspensions emulsions ointments soaps Powders Scavenger Hunt Bring back examples from clinic floor Water the universal solvent capable of dissolving more sublstanses than any other solvent Shampoos Go Go Go!! http://www.youtube.com/watch?v=i-hXcRtbj1Y Artist Access video Albert E http://www.youtube.com/watch?v=HZ_W3EAfp 6I
