BIOL 101 September 15‚ 2012 Assignment 1 Chapter 1 2. What is Homeostasis‚ and why is it important? Give some examples that show how systems work together to maintain homeostasis? Homeostasis is a term used to describe an internal environment being in a state of constant conditions‚ such as constant temperature‚ pH‚ and etc. It is important because staying at an equilibrium requires the least amount of energy and provides the perfect environment for desired reactions to occur. If at any given

Abstract In the Lab Determining the Empirical Formula of Magnesium Oxide‚ students set out to find if there is a true 1:1 ratio in the empirical formula of MgO. This was determined by burning the Magnesium until a white smoke started to protrude. This showed the reaction of Oxygen combining with Magnesium to form Magnesium Oxide. This was then measured again and turned out to be slightly heavier than the measurement before. This added weight is Oxygen‚ forming the combustion of Magnesium Oxide.

moles of wanted substance to desired units. Converting from Grams to Moles NOTE: One mole of anything contains 6.022 x 1023 atoms Atomic weights on the periodic table are given in terms of amu (atomic mass units)‚ but‚ by design‚ amu correspond to the gram formula mass. In other words‚ a mole of a 12 amu carbon atom will weigh 12 grams. The gram formula mass can be used as a conversion factor in stoichiometric calculations through the following equation: Moles = Converting between Volume
