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‚ which leaves

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules

Lava This presentation will discuss two questions which are How is Lava Produced? And What hazards/dangers does lava pose? It will also study one example of a Lava Flow in Hawaii. Lava is molten rock expelled by a volcano during erupting. It is produced/ formed in the interior of planets including Earth and their satellites. When the lava is first erupted from the vent in a volcano otherwise known as the volcanic vent‚ lava is a liquid and varies from 700°C to 1‚200°C. Although lava is

Introduction The Delphi method was developed in the 1950’s with the purpose of soliciting expert opinion in order to reach consensus (Dalkey & Helmer‚ 1963‚ p. 458). It was so named because it was originally developed as a systematic‚ interactive means of forecasting or prediction‚ much like ancient Grecians came to the Oracle at Delphi to hear of their fortunes. The approach relies on a collection of opinions from a panel of experts in a domain of real-world knowledge‚ and aggregates those
