The Identification and Production of Materials 1. Fossil fuels provide both energy and raw materials such as ethylene‚ for the production of other substances. Students Learn To: .2 Identify the industrial source of ethylene from the cracking of some of the fractions from the refining of petroleum. • Ethylene is produced either from natural gas or crude oil‚ which are mixtures of hydrocarbons. One method involves… Cracking: a process by which hydrocarbons with higher molecular

IV/ Written work: 2. Waiting for the Shop to Open Waiting for the shop to open (1943) is a painting by L. S. Lowry. Laurence Stephen Lowry was an English painter and became well-known for his oil paintings of industrial and urban landscapes of the North of England in the mid-20th century. The scene of the painting takes place in a street which is in front of a greengrocer’s shop called “fish and fruit”. Furthermore‚ the number of the street‚ 117‚ on the door’s shop was the same as Lowry’s house:

Copper Sun By: Sharon Draper The novel Copper Sun is a searing work of historical fiction and is action-packed‚ multifaceted‚ and character-rich. It describes a young girl’s life that was stolen from her village‚ sold to the highest bidder‚ enslaved‚ beaten‚ and mistreated. It expresses the different emotions that were felt as the girl went through her long and tiresome journey. Throughout‚ the young girl named Amaris journey‚ she encountered several different characters with similar but different

f) An ionic compound is a giant structure of ions. Ionic compounds are held together by strong electrostatic forces of attraction between oppositely charged ions. These forces act in all directions in the lattice and this is called ionic bonding. g) When atoms share pairs of electrons‚ they form covalent bonds. These bonds between atoms are strong. Some covalently bonded substances consist of simple molecules such as H2‚ Cl2‚ O2‚ HCl‚ H2O‚ NH3 and CH4. Others have giant covalent structures (macromolecules)

Introduction This lab proposed the question of what happens when copper chloride and iron are combined and what is the balanced equation.By completing this lab‚ the goal was to determine the equation and product for the reaction of iron (Fe) and copper chloride (CuCl2). It was predicted either solid iron or solid copper would form. Methods To begin‚ 6.00026 grams of copper chloride was dissolved in 50ml of distilled water in order to have a solution with charged iron and chlorine atoms. Then‚ 6

Problem Does temperature affect the resistivity of different sized copper wires? Hypothesis I think that the resistivity will increase with higher temperatures because with higher temperature‚ resistivity is higher due to the fact the atomic lattice structure increases. Background Electrical resistivity is the measurement of how a material opposes the flow of an electrical current. On the other hand‚ electrical conductivity () is the inverse of resistivity. It is the measurement
