mol-1 and +33.86 kJ mol-1 respectively. Calculate the standard enthalpy of reaction, in kJ mol-1 for the formation of N2O4 from NO2. 4. The combustion of one mole of ethylene (C2H2) gas to form carbon dioxide and water releases 1299.4 kJ of heat energy. (a) Write a balanced thermochemical equation for this reaction. (b) State whether the reaction is exothermic or endothermic. 5. Enthalpy changes for the following reactions can be determined experimentally. 4Al(s) + 3O2(g) → 2Al2O3(s) ΔH =

space and has weight. It comprises of atoms and molecules that are constantly in motion due to energy that they possess. Energy is present in all matter mostly in form of heat energy. Energy takes various forms and can change from one form to another form. Other than heat energy, various forms of energy include electrical, light, mechanical, chemical, sound and nuclear energy. These different forms of energy can cause a substance to heat up by simply increasing the speed of the molecules in the matter

Introduction Most of us have had a job at some point in our lives. In my experience, younger people today take advantage of the fact that they get additional breaks other than their lunch breaks while working. Unfortunately, what they don't realize that these additional breaks that they've received while working in their retail jobs are mandatory based on the companies that they work for, not mandated by federal law. Up to 75% adults who are in the throws of their careers don't take their lunch

substances present in its surroundings, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis). They are the producers in a food chain, such asplants on land or algae in water, in contrast to heterotrophs as consumers of autotrophs. They do not need a living source of energy or organic carbon. Autotrophs can reduce carbon dioxide to make organic compounds for biosynthesis and also create a store of chemical energy. Most autotrophs use water as the reducing agent

PROJECT IN SCIENCE 9 Submitted by: Rogie Marie C. Abecia Submitted to: Ms. Teresita Nanales March 20, 2015 THE FLOW OF ENERGY AND MATTER IN ECOSYSTEM When we think about ecosystems, we need to think both big and small. We need to consider the recycling of atoms between organisms and within their environment and the flow of energy through living organisms and its changes from one form to another. We need to appreciate the relationships between organisms, and between organisms and their

To be led like a machine is when things run smoothly and the same way at all times. It would be very boring and just something that is possible for humans because we are not robots. Some advantages of having robotic employees are: * Everyone would perform at the same rate and produce the same level of quality * If a person was broken one would only need to call a repairman to make a quick repair then back to work * No one would have feelings or egos * The could work for as long

Problems: When Derek was hired there was a lot of was worry that he would be underqualified and unexperienced. As well that he was only being hired because he was the owner’s son-in-law. These worries were reinforced when Derek was unable to accurately quote customers on the jobs that his department was supposed to do. As well Derek didn’t complete many invoices meaning some jobs where the work had been done were not being billed to the clients. When approached about these invoices Derek pawned
