Lab 4: Le Chatelier’s Principle Name: Cammey Mahowald Lab Partners: None Date of Experiment: March 16‚ 2015 Course: CHE 112 Abstract: The purpose of this experiment is to understand the components of a reaction at chemical equilibrium and use Le Chatelier’s principle to predict the direction an equilibrium position will shift upon changes in the concentration‚ temperature‚ and pressure. It was determined that in the equilibrium of chromate and dichromate it is an exothermic reaction and in the

Ecosystem and Living Organisms By: Tiepha Bridges University of Phoenix Instructor: Jonathan Neville February 29‚ 2012 Ecosystem and Living Organisms Gray wolves were once free to roam across Northern America‚ but this was before people hunted‚ trapped‚ and poisoned them. The drastic reduction of the Gray wolves in Northern America was a devastating blow to the ecosystem‚ but their extinction marked a critical loss

Observing Ecosystems Ecosystems-The sums of all the organisms living within its boundaries and all the abiotic factors with which they interact. Chemical Elements such as carbon and Nitrogen are cycled among abiotic and biotic components of the ecosystem. Photosynthetic organisms assimilate these elements in inorganic form from the air‚ soil‚ and water and incorporate them into their biomass‚ some of which is consumed by animals. Both energy and matter are transformed in ecosystems throught

In the rainforest ecosystem‚ everything is connected to one another. There is an interconnectedness existing in this ecosystem. To continue to function‚ the ecosystem depends on the interactions between the biotic and abiotic factors. An ecosystem survives by a combination of energy flow and matter recycling. To understand the interconnectedness of the ecosystem‚ food webs and food chains could be observed. Each organism depends on each other to survive and maintain their populations. In the food

The Ecosystem of the Florida Everglades The Florida Everglades is a vast wetland ecosystem made up of marshes and swamps. This ecosystem begins at Lake Okeechobee‚ a large lake in central Florida‚ and ends in the Gulf of Mexico and Florida Bay. It is nearly 50 miles across and 110 miles long and contains mile after mile of shallow water flowing through thick mats of

Lab 4: Endocrine System Physiology | 1. | | Refer to Activity 1: Determining Baseline Metabolic Rates. How did the baseline metabolic rates of the three rats differ? Answer: | The metabolic rates for the thyroidectomized and hypophysectomized rats were lower than that of the normal rat. | | | 2. | | Why did the metabolic rates differ? Check all that apply: Answers: | The hypophysectomized rat lacked thyroid-stimulating hormone. The thyroidectomized rat lacked thyroxine hormone.

this project because in previous years and class we were just well known about the term “ecosystem” but now as we have done this project we have now learned various things about ecosystem in depth and that will help us in our course study in coming days. This project is based on term “ecosystem” and “Food chain” after going through it many will be able to answer these questions: * What is an ecosystem‚ and how can we study one? * Is the earth an open or closed system with respect to energy

Greenhouse Effect And Ecosystem Environment plays an important role in human life. Nowadays‚ people are trying to take care of this environment‚ to ensure the prosperity and happiness of their life . Environment or ecosystem is the interaction and interface between living things (biotic) and non-living (a biotic) in nature. Biotic component includes all kinds of living creatures such as humans‚ animals‚ plants and micro organisms. Whereas a biotic components include non-living components such
