The Effect Of Cellulose On The Chemical Equation

Combustion Reaction: A chemical reaction between a fuel and an oxidizing agent that produces heat.

2. Used a test tube clamp to held the test tube and gently heated the tube in a laboratory burner flame for about 30 seconds.

This device was able to extinguish small, controlled fires created with an alcohol accelerant, proving that the concept is viable

burned was observed and recorded. Throughout part A and B, a centrifuge was used to separate

The experiment can also be done to compare the burn rate of different colored candles.

The experiment first started by the calculation of the net oxygen production under white light, it started by putting the Elodea in a volumeter tube containing 3% sodium bicarbonate solution, which was assembled to the volumeter by covering the tube with the plug/pipet/syringe assembly (a 1-2cm air space between the bicarbonate solution and the top rubber cover of the volumeter tube should be left.) Then, clamp the volumeter onto the clamp stand using the tube clamp and fill 2000ml beaker with cold tap water. The beaker should be placed on the clamp stand between the volumeter tube and the light lamp. A five minutes stabilization

Oxygen, O2, is a kind of gas. A lot of the air we breathe as human beings is oxygen. Which is good since we need oxygen to stay alive. Oxygen is also a primary element in fire. Fire is a chemical process. Three elements are needed for this process: oxygen, heat and fuel. Without one of those

In a combustion reaction, a compound or element reacts with oxygen, releasing a large amount of energy in the form of light and heat.

Place the Elodea in the water, start the stopwatch and measure and record the amount of oxygen bubbles produced by the Elodea over a 5-minute period.

Turn on the gas burner and bring it a low heat, only to the point that there is a blue flame. Carefully push the gas burner under the crucible and heat for around two minutes in order to properly rid the crucible of any bacterias or other impurities that may affect the lab.

Light a butane safety lighter and bring the flame close to the alcohol in the evaporating dish.

A more detailed explanation of procedures can be found in the lab packet.1 To summarize, samples of benzoic acid and naphthalene were combusted using the Parr 1341 Calorimeter with a Parr oxygen bomb. A massed benzoic acid pellet was placed onto the center of the combustion pan and 10 cm of nickel alloy fuse wire was massed and then threaded through both electrodes on the head of the bomb so that it lay firmly against the acid pellet. 1mL of distilled water was then placed in the bottom of the bomb in order to ensure that all the water produced by the

Fire is explained in a tetrahedron of necessary requirements a fire needs before it is able to spring to life. First, is sufficient fuel. Different types of fuel coincide with different types of terrain. In dry, sparse areas, dead grass and shrubs provide the best fuel. In lush, green forests, pine needles, leaves, twigs, and other such things typically underfoot makes for the best fuel . Second, is an oxidizing agent. This could be the oxygen

Fuel is a less combustible material that burns slow and steady once lit, like tree trunks, coal and oil. To start a fire, first the tinder is lit on fire. Then the kindling on top of it catches fire. When the kindling produces enough heat, the fuel will catch on fire. When all three ingredients are present in the correct amount, oxygen, heat, and fuel will start a fire and keep it burning.

1. Number four clean test tubes 1-4. 2. Place 1 ml (or 20 drops) of the following solutions into each tube: water, egg albumin, starch, and chicken broth. 3. Add 3 drops of Buiret reagent to each tube and gently shake
