Chemical vapor deposition

Atomic mass: the mass of an atom of a chemical element expressed in atomic mass units; approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes Molar mass: a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance Mole: the amount of a substance contained in 6.02 x 10²³ particles of that substance…

concerns the fact that sulfur holds much blame for the nasty occurrence. In fact, this mother of repulsive odors earns its spot on the periodic table as one of the world's 118 chemical elements, or substances that contain only one type of atom. Much like any other non-metal, it does not retain the typical physical and chemical properties of metals, such as luster. The tenth most abundant element in the universe, sulfur additionally sports a multitude of unique characteristics- some even…

The goal of this lab was to determine the heat of fusion of ice (or water). According to Chem.Libretexts.org, Heat of fusion is where solids are heated to a specific heat capacity (The number of heat units needed to raise the temperature by 1 degrees) in order to break the bonds that are keeping them attached, which is called the attractive force. This lab also dealt with the concept of the direction in which a temperature follow. According to chemistryexplained.com, temperature is the measure…

The purpose of today’s lab was to determine how effective antacids are at neutralizing HCl. This experiment required us to place 3 antacids tablets into 3 Erlenmeyer flasks. Next we were required to add 50.00 mL of 0.500M HCl and five drops of phenolphthalein. Finally, we needed to titrate NaOH into the flasks. Each antacid brand required a different amount of NaOH in order for it to be completely titrated. The data collected from the experiment allowed each group to calculate the cost…

There are many different types of mass destruction that have and can kill individuals. The four chemical agents include nerve, blood, choking, and blistering agents. The first type of well-known chemical agent is nerve agents. Nerve agents affects individual’s nervous system within the body and that is how it gets its name. Nerve agents were heavy used during the second World War (“Nerve Agents,”2017). According to “Nerve Agents” (2017), nerve agents are within the group of organo-phosphorus…

Conclusion At first, my hypothesis was that P-waves would move faster than S-waves. I thought this because P-waves went straight and S-waves where lobbed to the side. My hypothesis was correct, since P-waves had a more focused channel of energy unlike S-waves, which bended to the side. This causes S-waves to go slower and P-waves to go faster. When the experiment was done, P-waves averaged at .64 seconds and S-waves averaged at .68 seconds. On the P-wave experiment, I pulled the spring back…

In this lab procedure, lab groups were split by the type of lab procedure they would perform. Half the lab groups were tasked to perform simple distillation while the other half performed a fractional distillation. Before beginning the procedure for the fractional procedure, materials were gathered. The lab procedure with the lab manual called for a short neck round bottom flask; however, this was not followed during the actual lab. Instead, the long round bottom flask was used. In addition to…

Discussion Enzymes are biological catalysts that help speed chemical reactions. In part A (table 2), it was seen that a normal reaction of catalase and hydrogen peroxide resulted in the release of bubbles (oxygen gas) and the release of energy in the form of heat which shows that the reaction was a exothermic reaction. The reaction was given a reaction rate of four and acted as the control with which we could compare the other results to. When testing whether or not catalase is reusable in part…

Over the course of the roller coaster height lab My group and I had to answer the question “ does the height of the ramp affect the speed of the marble”. We answered that yes the height of the ramp will make the speed of the marble increase. Our hypothesis was wrong, but, My group and I have discovered that the height of the ramp will not affect the speed of the marble. We also Discovered something new which was that the speed increased and decreased abnormally as we went along in the lab. Over…

~~~Science Project~~~ Experiment 1: Materials~ 2 eggs Needle Scale Bowl Marker Question? What is the difference between weight and mass, and can two objects that have the same mass be different weights? Hypothesis The difference between weight and mass is that mass is the measurement of how much matter is in an object and it will remain constant regardless of gravity. Weight is how heavy an object is depending on the gravitational pull on the object. Step 1: Zero out the scale. Step 2:…
