Mole Ratios Lab October 10‚ 2013 Mrs. Oliver Noah Kent AP Chemistry Block 3/4 Laboratory #4: Mole Ratios I. Hypothesis: If copper wire is placed in an aqueous solution with silver nitrate‚ then silver crystals will grow on the wire surface and the solution will gradually take on the color of Copper (II) ions. The relative quantities of reactants and products in this chemical reaction can be determined by measuring the mass of copper wire consumed in the reaction and the mass of silver crystals

Assess the importance of ideological differences in the outbreak of the Cold War. The two opposing ideologies of the 20th century were Capitalism and Communism and some consider them to be responsible for the growing tensions of what would later become the Cold War. Capitalism found its home in the West‚ and specifically in the USA and was based on private ownership‚ the means of production and the creation of goods or services for profit. It also incorporated competitive markets‚ wage labour and

Observation of Planarian Abstract: The objective of this lab report is to report our findings on the planarian. We extracted the planarian from a beaker and observed them under a microscope. We observed its sensitivity to touch on different parts of its body‚ its sensitivity to talcum powder‚ its reaction to a small piece of liver‚ and its sensitivity to light. Introduction: The problem we are investigating is how sensitive it is to touch on different parts of its body‚ its sensitivity to

Since the Grignard reagent can easily react with water‚ all glassware including the 25 ml round bottom flask‚ magnetic stir bar‚ 3 and 5 ml conical vial‚ 50 mL Erlenmeyer flask‚ claisen adapter‚ drying tube and 5 glass pasteur pipets were first added to a 250mL beaker and placed in the oven for 30 minutes. After the completion of the thirty minutes‚ 0.150 g of shiny magnesium turnings and a stir bar was first added to the round bottom flask and the claisen adapter along with the drying tube packed

the opposite force (air resistance)‚ which is acting on the wings will get weaker because the wings will fold upwards. This will cause less for the air resistance to act on which will cause the speed to increase. Method: For our helicopter lab‚ we first measured two meters on the wall so we have will drop the helicopter at the same place. Then‚ Eliah will drop the helicopter and Holly will time how long it takes with the stopwatch. We repeated this step for three mores tests and with two
