Density = m/v Questions: Which liquid in the picture to the right is most dense? Which liquid has the greatest volume?

Classification of Matter

Acids & Bases Acids taste sour, are corrosive to metals, change litmus (a dye extracted from lichens) red, and become less acidic when mixed with bases. Acids release hydrogen ions in solution. HCl H2O→ H+(aq) + Cl-(aq) Bases feel slippery, change litmus blue, and become less basic when mixed with acids. NaOH H2O→ Na+(aq) + OH-(aq) The neutralization reaction of an acid with a base will always produce water and a salt, as shown below: Acid Base Water Salt HCl + NaOH → H2O NaCl HBr KOH KBr

Radioactive Decay

Radioactive Half-life The half-life of Cobalt-60 is 5.3 years. After 10.6 years how much Co-60 is remains? 25% of original or 1/2 x 1/2 = 1/4

Nuclear Fission 1)A neutron strikes a uranium atom 2)The uranium atom is split into a krypton atom and a barium atom releasing some binding energy along with more neutrons. 3)The neutrons strike other uranium atoms starting the process all over again.
