change the activation energy needed. A catalyst increases the reaction rate by lowering the activation energy needed. Although catalysts affect a reaction s rate, they are not permanently changed by a reaction and are not considered reactants. Many chemical reactions can normally only happen at temperatures that would kill living things.

Structural Isomers Just how many structures can you make

As before, we will begin with a five carbon straight chain isomer. There are 12 additional bonding sites, all filled with a hydrogen atom. C5H12 is saturated and it is ambiguous. Rotation is possible about any of the carbon-carbon single bonds, generating different conformations. Build a model and try it. C C C5H12 C H C H H condensed formula

b. Change ane to yne and assign a position number to the first carbon of the C tC. Note: The Group B functional groups (alkene and alkyne) are considered to have equal priority: in a molecule with both a double and a triple bond, whichever is closer to the end of the chain determines the direction of numbering.

Chemical Property: Any characteristic that gives a sample of matter the ability/inability to undergo a change that alters its composition. Examples: Alkali metals react with water; Paper's ability to burn. Chemical Change: Change in which one or more kinds of matter are transformed to new kinds of matter with altered compositions (or

and a system can even change in size with time. An isolated system is a system that does not exchange heat, work, or material with the surroundings. If heat and work are exchanged across a system s boundary, but material is not, it is a closed system. An open system can exchange heat, work, and material with the surroundings. Examples.

Determining the Formula of a Hydrate

hydrate is heated. However a color change does not usually occur for white crystalline hydrates. This experiment will also illustrate the law of conservation of mass and the law of definite proportions. The law of conservation of mass states that the total mass remains constant during a chemical change or chemical reaction. Atoms are not destroyed,

Large numbers { using Stirling s approximation to compute multiplicities and probabilities Thermodynamic behavior is a consequence of the fact that the number of constituents which make up a macroscopic system is very large. We need to get good at dealing with large numbers.

δ= is used to signify chemical shift. Because the frequency depends on the field strength, one uses a relative units scale of parts per million or ppm Chemical shifts reported as ppm units give the same values for the same compound regardless of the instrument used! δ = (v (compound)- v (TMS))/ v (TMS)

Causes of Climate Change - United States Environmental

Causes of Climate Change. Climate change is a term that refers to major changes in temperature, rainfall, snow, or wind patterns lasting for decades or longer. Both human-made and natural factors contribute to climate change: Human causes. include burning fossil fuels, cutting down forests, and developing land for farms, cities, and roads.
