Lab Questions On Environmental Solutions

In this experiment, there were 6 different test tubes, each containing a different amount of phosphate concentration. Using a balance, 1 g of phosphate in a 400 mL beaker was measured and then inserted into a 100 mL graduated cylinder. 5 mL of ammonium vanadomolybdate (AVM) was added, along with deionized water until the solution reached to 25 mL. Then the solution was poured into one of the six test tubes. Another test tube contained 2 g of phosphate (phosphate was again measured using the balance) and the step described earlier was repeated until five of the six test tubes were filled, each with the same volume of 25 mL. The sixth test tube was filled with only deionized water, with 25 mL as the volume. A spectrophotometer was then used to determine the percent transmittance for each solution. The absorbance was also calculated using the equation A = -log (T). Each given amount of phosphate was converted into moles and then applied the value of .025 L for the volume to calculate the molarity of phosphate in each solution.

electromagnetic spectrum. If there is enough of each chemical to be visible when energized, the light bands that can be seen with a spectroscope may be used to identify the various ions (metal). Light emitted from each is different, allowing for a viewer to say what unknown is what chemical.

Electromagnetic radiation are electromagnetic waves, or photons, that are emitted by astronomical bodies and travel in all frequencies (Auger, 1964). Particle radiation, on the other hand, are charged particles traveling at high speeds, protons, and even nuclei of other heavier elements. These particles tend to travel near the speed of light, so fast that their electrons are completely striped from

Secondly we have Electromagnetic Radiation. Basically the study of Electromagnetic Radiation is dealing with how much electrically charged particles come together with each other with Magnetic fields. EM

The post is quite interesting and the ethical considerations come handy for our projects currently in construction. Certainly, there is no secret that human beings throughout history have always being determined to better themselves. However, the issue here presented is that more than taking advantage of the combination of technology with other fields to correct health issues, address the environmental conundrums, or in simple terms to improve the quality of life of other humans beings in need. Humanity is entering the point that the so call transhumant evolution changes are far from what is necessary to the point where the manipulated change is simple by will, depending more on the personal interests, a lifestyle.

Electromagnetic Radiation can help us in various ways to learn about matter in the universe. It helps us by determining the location of matter in the universe, planets for example. The waves that bounce back at a certain time can determine the distance between you and the planet. NASA and other people have come up with many ways of finding matter in the universe. There is a lot of ways to find matter in the universe but this is the most popular. The type of wave it sends back may be ragged or straight because of the surface that it is bouncing on. Radio waves and microwaves are used to observe interstellar clouds and track where the dark gas might be heading. Infrared waves that we can see from very powerful telescopes

Spectroscopy is a field of chemistry used to analyze chemicals in food and pharmaceuticals all the way to determining the age and compositions of the stars and galaxies (Santiago et al. 2015). For the lab we performed over the past two weeks we were using spectroscopy to test and understand the interactions of UV-visible radiation and organic molecules in commercial products such as food dyes. The spectroscopy is used in commercial products to find the exact concentrations of each dye, how much UV-light is absorbed correlates to how concentrated the dye is in the commercial product; or in our case how much concentrated dye is in each solution. We were give three dyes to perform the experiment they were red dye 3, yellow dye 5 and

Tracing- a tracer is a chemical compound, where more atoms have been replaced by a radioisotope so by its virtue radioactive decay it can be used to explore mechanisms of chemical reactions by following the path that the radioisotope follows from reacted products

Electromagnetic radiation which includes waves such as radio waves, microwaves and visible light. Theses waves all fall under the same spectrum known as the electromagnetic spectrum. Electromagnetic waves occur when orbital transitions take place such as ionization and excitation and can produce radiation such as characteristic x-rays and Auger electrons. Particulate radiation is radiation that is made from fast moving particles also known as a particle beams. Some examples of particulate radiation are alpha and beta particles. Particles have mass unlike photons in electromagnetic radiation.

EM Waves are used all over the world and help the human life easier to live. They have helped discover and make things way easier. Electromagnetic waves are used all over the place everyone uses them. For example your camera uses Electromagnetic waves to get the picture that simple. Mankind could not live without EM waves because it would be hard to come up with devices that don’t use EM waves. Electromagnetic waves were found and made a huge impact to mankind.

For instance, the speed of light has been measured at roughly 670 million miles per hour (Wile 365). With some math, scientists have learned that light can travel the circumference of earth approximately 7 times each second and that it takes around 8 minutes for the sun’s rays to reach earth. Scientists can now calculate the wavelength, which is the distance between two crests, and frequency of a light wave, but also the energy of a photon at the same time and use the values interchangeably (Wile pp. 352 and 373). The electromagnetic spectrum, the collection of all forms of light, shows that visible light is only a small fraction of all light. The spectrum ranges from energetic gamma, X-ray, and ultraviolet radiation to relatively low-energy light waves such as infrared, microwave, radar, TV, and FM and AM radio. Visible light, also known as the visible spectrum, sits between ultraviolet and infrared. It is the only portion of the electromagnetic spectrum that humans can see (Wile 370). Although much of the spectrum is unperceivable to the eye, it has numerous uses. For example, X-rays are used to find broken bones and treat cancer, infrared light is used in remote controls, microwaves heat food, and FM and AM waves are used in

Background: Electromagnetic Field: (noun) a field that is made up of associated electric and magnetic components that result from the motion of an electric charge. It also possesses a definite amount of electromagnetic energy.

It consists in measuring the number and energy of ions in a beam backscatter after collision with the near surface of a sample , wherein the beam was targeted region atoms .

* Light is part of the electromagnetic spectrum, the spectrum is the collection of all waves, which include visible light, Microwaves, radio waves ( AM, FM, SW ), X-Rays, and Gamma Rays.
