Conclusion 1) One error could be if the Magnesium did not heat all the way, then there were still solid pieces of Magnesium that could have made the mass greater. Extra mass in the crucible could cause the oxygen to be too low because extra mass would consume more space and would lessen the amount of space for oxygen within the crucible. 2) a. If you put more water in to the crucible than is needed for reaction 3, and did not wait for the excess water to dry out, then there would be to little oxygen. This is because the product in the crucible and the water would increase the amount of weight of the crucible/product as a whole and would leave little space for oxygen.

9.1: Catabolic pathways yield energy by oxidizing organic fuels. Redox reactions: oxidation and reduction. The stages of cellular respiration. In redox reactions the loss of e- from one substance is called oxidation. The gain to the other is known as reduction. The harvesting of energy from glucose by cellular respiration is a cumulative function of three metabolic stages: Catabolic pathways and production of ATP Organic compounds possess potential energy because of the arrangement of electrons in bonds between atoms. Compounds that participate in exergonic reactions can act as fuel. Enzymes help cells degrade complex organic molecules that are rich in potential energy. This breakdown can provide energy to

Chapter 5: Thermochemistry ?Introduction- Energy is defined as the capacity or the ability the to do work i.e. in order to do work energy must be involved Mathematically Represented- Work or Energy = Force x Distance The view of energy can be thought of as physical in nature and contact via the exerted force Chemistry, however, must view energy differently. The study of energy and its transformation, as it applies to chemistry, is know as THERMOCHEMISTRY, along with spontaneity, the two are referred to as THERMODYNAMICS Section 5.1- Nature of Energy The study of chemistry and thermodynamics will involve the concepts of energy, work, and heat KINETIC and POTENTIAL Energy Kinetic ? energy due to an objects motion

Ecosystems- consists of all the living things in a particular area, along with all the nonliving components of the environment with which life interacts. Ex. forest The biosphere is composed of ecosystems Communities- the entire array of organisms inhabiting a particular ecosystem. The set of populations that inhabit a particular area Populations- consists of all the individuals of a species (forms of life) living within the bounds of a specified area

Glowing Tonic Water Fountain Diana Luna 2B Purpose The purpose of this demonstration is to display the fluorescence of tonic water under a black light and a recreation of Hero?s fountain, which defies the laws of gravity. Supplies Tonic water (preferably 0.75 L) 2-2L soda bottles Fountain connector Black light (or UV light) Tray (to catch overflowing tonic water) Procedure Obtain and clean out two 2- liter soda bottles. Fill one bottle ? full with tonic water. Screw fountain connector onto both bottles. Turn bottles over and fountain will erupt. Why does tonic water glow?

Name: ________tyler antebi___________________________ Pg.___1 Mrs. Strype - 8 Acid Rain Internet Activity Sulfur dioxide and nitrogen oxides from the burning of fossil fuels react with water and oxygen to form acids. Rainwater is naturally slightly acidic, but this additional acid makes it even more so. Acid rain harms wildlife and upsets the balance of an ecosystem. In this activity, you'll learn what acid rain is and how you can help reduce it. Go to the website What is Acid Rain? What's the definition of acid rain? Acid rain is referring to a mixture of wet and dry materials from the atmosphere containing high amounts acid. Compare wet and dry deposition. Wet Acidic rain, Snow, Fog Acids fall in types of wet or moist weather. Dry Dust, Smoke
