Kinetics of an SN1 reaction: the effect of solvent on rate Object The purpose of this experiment is to determine the rate of hydrolysis in acetone/water (50/50 v/v and 60/40 v/v). Background and Theory An SN1 reaction of tert-butyl chloride takes place in two steps. First‚ the Alkyl Halide will leave the molecule. In this step the bond is breaking‚ which takes a longer amount of time‚ so it will determine the rate of the reaction. As a result‚ it forms a tertiary carbocation‚ since this

science fiction films began portraying technology and foreign invaders as potential threats on our national security‚ as a result of the growing international tensions and rapid technological growth between nations. The 1999 science fiction film The Iron Giant by Brad Bird is a film that want to revamp the Cold War view of technology by comparing the 1950s view with the modern age audience. The story takes place in the 1950s and is about an extraterrestrial robot that becomes a concern for many people

In chapter one of The Iron Cage‚ Rashid Khalidi sets the stage for the premise of his book‚ by examining the conflicting evidence of the Palestinians’ plight. In order to do so‚ the narrative begins in 1948‚ following the eviction of more than half of the Arab Palestinian population as a result of the Arab – Israel conflict of that year. Khalidi goes on to enumerate a few of the respective differing Arab and Israel accounts of how it was that a people that once constituted the majority of the population

uniform disk of radius R = 0.25 m has a string wrapped around it‚ and a m = 3 kg weight is hanging on the string. The system of the weight and disk is released from rest. a) When the 3 kg weight is moving with a speed of 2.2 m/s‚ what is the kinetic energy of the entire system? KETOT = KEwheel+KEweight = (1/2)(I)(w2)+(1/2)(m*v2) =(0.5* v2)(m+1/2M) =0.5*(2.2^2)*(3+(.5*15)) J b) If the system started from rest‚ how far has the weight fallen?

The Iron Heel- Jack London The book I read titled The Iron Heel by Jack London was written as a dystopian novel. A dystopian has the opposite of what one would expect in a Utopian society. This as I see it means that what could have been a society of happiness and leisure was turned into a horrible and oppressive government. The middle class were used and bankrupted. People such as farmers were turned in serfs. This was a portrait of what might be to come from an oligarchy type of government

detail is meaningful because it shows that Emily had lain in that bed‚ next to that man‚ after he had died. Faulkner had given great detail to the change in color of her hair throughout her life on page 36. By the time she had died‚ her hair was an “iron-gray” color. Just like the strand of hair found on the pillow. 2. The unnamed narrator seems to be a representation of the townspeople as a whole. He is most likely a member of the town.

In this essay‚ it will be discussed how the Kinetic Molecular Theory explains many gas law specifically Boyle’s gas law‚ Charles’ gas law‚ and Avogadro’s gas law. To understand what will be talked about is to first know what the Kinetic Molecular Theory is. In our textbook is says it is “A simple model for gases that predicts the behavior of most gases under many conditions.” First off‚ we will take a look at Boyle’s Law. As stated in our lab manual “at constant temperature the pressure which a given
