in the summer‚ Cedar Point has a positive impact on the economy of Erie County Ohio. Thru tourism‚ expansion and charitable works they have improved the economy of the area a thousand times over. Each year Cedar Point draws millions of tourists to the area. Those tourists stay in hotels‚ eat at restaurants and buy souvenirs. “Tourists spent more than $1.75 billion in the county in 2005‚ making it one of the most popular tourist destinations in the Midwest.” (Cedar Point Infuses Ohio Town with

Purpose: The purpose of this lab was to determine the freezing point of pure water‚ the experimental van’t Hoff factor for a substance and the molar mass of an unknown solution. Reagents: 25mL deionized Water ¼ to ½ inches of rock salt 25mL Sodium Nitrate (NaNO3 ) 25mL unknown solution – handle unknown solution carefully Procedure: For part 1‚ the freezing point of deionized water was determined. An ice bath was prepared by filling a 600mL beaker ¾ full of ice and covered with ¼ to

indirect control of a colonized area. Repressed ethnic and national groups around the world heard Wilson’s call for "national self-determination" as the herald’s trumpet for a new era as the 14 Points list the foundation for world peace. Despite their introduction after World War I in 1918‚ the 14 points are still relevant today as these ideas establish peaceful ideologies in other countries worldwide to maintain their people. Woodrow Wilson made the Democratic Party a “party of reform” by creating

HOW TO FIND OUT POINT GROUP Dr. Cyriac Mathew Symmetry elements can combine in a definite number of ways. For example consider BF3 molecule. It has the C3 axis as the principal axis. Also‚ there are 3 C2 axes perpendicular to the C3 axis‚ 3 σv planes‚ and one σh plane. All these symmetry elements can combine. Take NH3. It also has C3 axis as principal axis. There are 3 σv planes‚ but no C2 perpendicular to C3 or a σh plane. For the N2F2 molecule there exist one C2 axis and a σh plane but

(1) Evaporation: Surface Area: Evaporation is surface phenomenon.Greater is surface area greater is evaporation and vice versa.For example‚ sometimes a saucer is used if tea is to be cooled‚ quickly.This is because evaporation from the larger surface area of saucer is more than that of the smaller surface area of the tea cup. Temperature: At high temperature‚ rate of evaporation is high because at high temperature

Nick Boyea Billy Lee 3/9/11 Molar Mass by Freezing Point Depression Overview The purpose of this lab is to measure the freezing point depression of a solution of an unknown substance and BHT to determine the molar mass of the unknown substance. Summary of Lab Procedure If not already completed‚ crush a small amount of BHT and pack it into a capillary tube. Use a small rubber band to clamp the capillary tube to the thermometer‚ and fasten the thermometer to a ring stand. Fill a Thiele tube

This paper is a full determination for certain chemicals and their boiling points. It lists some already but given the atomic numbers of any material this project includes a conversion and calculation chart to find the freezing point of most any material. GOOD LUCK! Abstract: In this lab we determined the freezing point‚ and Kf‚ of pure 2‚4‚dichloralbenzne as well as a 2‚4‚dichloralbenzne/biphenyl solution. We used this information to determine the molar mass of an unknown (#24) by the 3rd step
