Sun light vs articical light One of the main benefits of artificial light is that you can control how many hours of light per day your plants receive. This way‚ those living in northern or southern latitudes can provide their plants with light for growth and development even when the sun sets early‚ in essence tricking the plants into believing that it is summertime and that they should continue to grow rather than become dormant or‚ in the case of annuals‚ die. In addition‚ your plants will receive

The Melting Pot 1. Why has it been so difficult for Hmong refugees to adjust to life in the United States? It has been so difficult for Hmong refugees to adjust to life in the United States because lifestyle was very different from theirs. They didn’t know a telephone‚ an air conditioner‚ a light switch‚ etc. even existed. They wanted to keep their traditions‚ their culture. They were empty about new ideas and new experiences. This means that they were full of the past. Also‚ because they

Mixture Melting Points Abstraction Determining the melting point is very significant in order to identify an unknown. In this experiment‚ measuring the melting point was done by using melting point apparatus. The melting point of the unknown sample #10 was 111.5˚C. There were two possible compounds which were dibenzoyl ethylene and o-Toluic acid because their melting points were 111.2˚C and 109.8˚C when each compound was mixed with the unknown. Therefore‚ the unknown #10 was dibenzoyl ethylene

Introduction The melting point is defined as the temperature at which the solid is in equilibrium with its liquid‚ and this characteristic is very unique‚ so a substance can be determined by the melting point. Determination of the melting point is very important technique in many areas of chemistry especially‚ in organic chemistry area because the melting point is really significant in order to identify the purity and the identity of a substance. Measuring the melting point is a fast and cost-effective

The melting pot is a theory used to describe the American society in its first years. In the very beginning‚ the settlers in the “New World” had to create a totally new nation from many different origins and the proximate result of this situation was the birth of the melting pot theory. The idea behind it is that every immigrant

The two different views of America could change a whole country. The poster represents the "Melting Pot" America. The immigrants were to blend into the American culture and society. Rather than bringing their old country into America‚ and changing it. The poster is promoting to "Keep America Great‚" and "Learn the Language." The article states

Lab/ Chem 234 02/17/13 Lab 2: Melting Points Purpose: To determine the purity of a substance using melting point as physical property. We must also learn how to identify an unknown compound using its melting point. We got to identify an unknown compound using mixture melting point and finally we must learn to obtain an accurate melting point using Mel-Temp apparatus. Procedure: Set voltage to obtain the desired heating rate at the anticipated melting point range. The voltage control controls

Melting Point Determination Lab Materials: Graduated pipette Capillary tube Tin wipe Sample Melting temperature apparatus Thermometer Procedure: Take open end of capillary tube and tap it gently into sample. Take tin wipe and place over the opening. Gently tab it so the sample will funnel to the bottom of the tube. You may also use a graduated pipette to accomplish this. Now‚ place the capillary tube in the designated spot in the melting apparatus‚ and once placed‚ turn the apparatus
