These remains form sediments eg at the bottom of seas‚ and become buried under layers of sedimentary rock. They decay‚ without air (oxygen)‚ under the action of heat and pressure to form crude oil over millions of years. It is a fossil fuel because it is formed from

Epoxidation Reactions Lab Report 2 Abstract An oxygen atom is transferred from a peroxy acid to the carbon=carbon double bond thus forming an epoxide. Scheme 1. Oxone Epoxidation. Scheme 2. mCPBA Epoxidation. The percent yield for the Oxone epoxidation reaction was 65% yield and the mCPBA epoxidation reaction was 70% yield. Oxone is the greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic

Tashia & Tobi Lab Report experiemt 5 INTRODUCTION In this experiment we were wanting to find the specific heat of an unknown metal and determining what metal it was by using the formula q=c X m X change of temperature. We did two trials to compare the two and see what we come up with. EXPERIMENTAL First we chose an unknown metal‚ in which our unknown was unknown metal 2‚ the metal was gray and irregular shaped. We setup the calorimeter and got a mass of it just being empty then we got
