Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy D. F. Nachman 6/23/2010 Abstract: An ice calorimeter was used to study the reaction of magnesium metal and 1.00M sulfuric acid solution: Mg(s) + H2SO4(aq) →MgSO4(aq) + H2(g). We found the experimental molar enthalpy of reaction to be ΔH = –355 ± 17 kJ/mol at 0°C‚ 24% lower than the textbook value of ΔH° = –466.9 kJ/mol‚ reported at 25°C. Introduction Whether a chemical reaction occurs spontaneously or is driven by an outside

I believe Robert Frost’s poem “Fire and Ice” is meant to express. Although the poem is short‚ it holds a very interesting question to think about. What way would you prefer the world to end? There are two choices. In his poem “Fire and Ice”‚ Robert Frost compares and contrasts the two destructive forces: fire and ice. In the first two lines of the poem he presents two options for the end of the world‚ “Some say the world will end in fire‚ Some say in ice”. I feel that he uses the term fire‚ not

On the surface it seems to just be about the possibilities of how the world will end in either fire or ice‚ and how Frost personally would prefer the world end in fire over ice. However under all of that‚ Frost lays bare to the

Caribbean history begins with an examination of the indigenous peoples (Amerindians/neo-Indians) who populated this area thousands of years ago. These indigenous peoples had developed societies that spread across the Americas‚ the Caribbean‚ and parts of South America and Central America.

I lacked the basic skills that other skaters my age had already mastered. However‚ as an athlete‚ I had heart.

Although‚ ice hockey gave me confidence I would otherwise not have‚ digging
