Essay importance chemistry agriculture

Chemistry deals with the matter that form our environment and the transformation that the matter undergoes. Chemistry is therefore, useful in understanding the changes taking place in the constituents of the environment and the resulting advantages. Chemistry is connected with composition, structure and properties of the matter.

Next, I will pour the tetracosane crystals onto a clean sheet of paper crush them into a fine powder with the back of a spoon. A small amount of the powder will be collected and placed in the bottom of a glass capillary tube. My goal is to have the power occupy no more than 2mm of tube space; too much material will misguide a true melting point.

Once inside the tube, I will secure the tube alongside a thermometer with a small rubber band; careful to place the bottom of the tube directly above the bulb of the thermometer. The finished structure is then placed into the water bath.

It is critical at this point that water does not enter the glass tube. Once the compound is secure in the beaker of water, the entire unit is placed onto the burner stand. Ignite the burner fuel and gradually increase the temperate while closely observing the compound for changes.

Use caution in increasing the temperature gradually, as not to miss the correct boiling point and alter the data. A good standard to follow is increasing the bath temperature by no more than 5 degrees per minute. Record the temperate when the first drops of liquid are noted, as the crystals begin to collapse; also, record the temperature when all the crystals have become liquid.

These two measurements are the melting point range for tetracosane. Once the range is obtained, remove the thermometer and beaker. Pour out the hot water and allow both the thermometer and the beaker to cool.

Once cool, repeat the previous steps with the second compound, tetradecanol. At the conclusion of the second experiment, repeat the steps for a third and final time using an equal mixture of both compounds.

Be sure to record the melting point range for all three experiments. The reason for this instruction is that polymers and unpure substance melt over a range of several degrees. Based on the melting point ranges for both substances, it is difficult to differentiate the two based on its melting point data alone.

The ranges of the substances are close enough to one another that one could argue for experimental error when presenting the data as a solo identifying property. Based on these conclusions, I do not believe the tetracosane is a pure substance because I observed the compound melt over a range of degrees Celsius.

If both compounds in the mixture were composed of tetracosane, its melting point would be theoretically, identical to the melting point of the original experiment. However, the melting point of the mixture was below that of the original data, reinforcing the knowledge that adding a derivative to a compound will lower its melting point.

During the experiment, heating the water too quickly would create inaccurate data. If the water is heated too quickly, the thermometer may have a hard time keeping up with the temperate, thus displaying an inaccurate measurement. It would be must harder to obtain an accurate range, if this were the case, as the substance may melt faster than observable.

Melting points disrupt intermolecular forces, spreading atoms over a greater surface area; melting points do not affect covalent bonds, thus are not chemical changes.Chemistry is a Part of Life Dear Reader, For you to understand my personal importance placed on chemistry, you would first need to understand who I am in reference to chemistry.

So for starters I am a Christian, second a human, third a survivor, and fourth a biochemist. · Essay on the Importance of Study of Biology Biology and Agriculture.
