measurement. Changing to the metric system will make the United States be on the same system of measurement with the rest of the world. It will also prevent incidents like NASA’s Mars Climate Orbiter incident due to a failure of the engineers to convert units from customary to metric. According to NASA‚ peer review findings indicated that the cause of loss of the Mars Climate Orbiter was because one team used the customary system of measurement‚

calculations and understanding the results. The system decimal system makes it extremely easy to perform conversions and tracing children the metric system puts them in an advantage in the international marketplace. What are the disadvantages? The system does not work well with fractions un less it is divisible by 10. What about 1/3 it does not work with those types of fractions at all. One large difficulty is just the Us learning to use it and convert everything over to the system. There are economical

INTRODUCTION Thermodynamics is a branch of physical science in which deals with the relations between heat and other forms of energy. The ability to predict if a chemical reaction will occur spontaneously or non-spontaneously is an important aspect of thermodynamics. Spontaneity is determined from free energy‚ or Gibbs free energy. The equation (1) gives the relationship of how entropy (∆S) and enthalpy (∆H) along with temperature affects the amount of free energy‚ and henceforth the spontaneity

Chem Final Exam Combination Combination reactions‚ also known as synthesis reactions‚ involve the combination of two or more substances into a single new substance: A + B ---> AB Many metal oxides‚ for example‚ absorb carbon dioxide (CO2) from the air to form carbonates: CaO(s) + CO2(g) ---> CaCO3(s) Decomposition Decomposition reactions represent the reverse of the combination process in that one substance breaks down into two or more substances: AB ---> A + B Water‚ or H2O‚ for example
