Student Guide Laboratory: Drop and Bounce Different matter responds differently to force. In this lab‚ you will explore the relationship between matter and energy by dropping objects made of different materials from different heights to see how high they bounce. You will be dropping these objects in a virtual lab setting where objects behave the same as they would in the real world. Goals for the Lesson Solve a problem using the scientific method. Use the metric system in a scientific experiment
Premium Chemistry Science Laboratory
Purpose=The purpose of this lab was to combine reactants‚ which we would pick ourself‚ to make 2 grams of Copper Phosphate and another product. Background: Chemistry is the branch of science that deals with the identification of the substances of which matter is composed. Chemistry has to do with many things we use today. For example‚ fireworks are made by the chemical combining magnesium‚ titanium‚ copper‚ aluminum‚ strontium‚ or other periodical elements. Things also like making plastic‚ jewelry

Flame Lab Objective: How an electron absorbs energy and re-emits it as light and why different elements have different spectra. Also to learn how to use flame tests to determine the identity of unknown mixtures. Hypothesis: We know that certain compounds will burn certain flame colors because they emit different wave lengths. Introduction: Neils Bohr made the “Bohr’s Model” in 1922‚ he found that electron travel in specified fields – which‚ when excited‚ will jump to different rings

McLean 1 Creating Acetylene Gas Introduction The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel

of Oxalate Ion in Ferric Oxalate Trihydrate using Titrimetry Abstract: In this two-part lab‚ we will learn about coordination compounds and their uses with stoiciometry. We will also find out about how theoretical yield is calculated from a reaction we will create. We will also synthesize Potassium Ferric Oxalate Trihydrate (K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O) using a two step reaction. In the second part of this lab we will calculate how much Oxalate Ion is present in the K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O using

Introduction: The question investigated in this lab was which drugs have the greatest and least affect on the pulse of the Lumbriculus variegates. Ethanol will cause the worms to become inactive‚ caffeine will cause the worms to become overactive‚ and nicotine will cause the worms to become more active. Lumbriculus variegatus is also known as black worm. This small species of worms currently lives in North America and Europe within marshes and ponds. They survive by eating microorganisms and organic
