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:…

The Reaction of a food dye with bleach Introduction The overall purpose of the experiment was to determine the order in respect to the blue dye and the rate constant (K). With these found however, the overall rate law in the reaction between blue food coloring and the bleaching agent within commercial Clorox can be found. The orders in a rate law equation represent the relationship between the concentration of a given element or molecule and the overall rate, for example, when a reaction in…

following tests were performed using Erlenmeyer flasks containing NaCl.² The BioMnOx batch experiments were initiated by adding 150 mL of the buffered test solution to BioMnOx pellets and to the diclofenac stock. The chemical 〖MnO〗_2 batch experiments were initiated by adding the chemical 〖MnO〗_2 and diclofenac to 150 mL of the buffered test solution. The controls of this experiment consisted of distilled water and Pseudomonas putida cultures, which were grown in manganese free medium. Lastly,…

The purpose of the experiment is to perform a series of chemical reactions involving copper. The goal is then to perform precipitation, acid-base, decomposition, and redox reactions using the copper cycle. The mass of the copper was then analyzed using the percent recovery formula. Reaction 1: The Formation of Cu(NO3)2: Reaction 1 of the experiment involved performing a redox reaction to create Cu(NO3)2. Immediately after HNO3 was added to the copper wire (Cu), the brown NO2 gas was emitted from…

As macromolecular machines, enzymes conduct their designated work in the confined and crowded spaces inside living cells. How does a protein work in such a condition? Functions of proteins are strongly dependent on their structural stability and dynamics while the (macro) molecular interactions are arguably affected by the complexity and diversity of their environments. To date, two interrelated cellular conditions — ‘macromolecular crowding’ resulted from the effect of volume exclusion by…

Experimental Section - Chemicals Pyrrole, substituted benzaldehydes (p-anisaldehyde, p-nitrobenzaldehyde, 2,6-dichlorobenzaldehyde and benzaldehyde), triethylamine (TEA), p-terphenyl (TP) and ferrocene (Fc) were purchased from Sigma-Aldrich. Tetraphenylporphyrin (TPP) was purchased from Frontier Scientific. Acetonitrile (MeCN), dichloromethane (DCM), 1,4-dioxane, and other organic solvents used were spectroscopic grade. These solvents were distilled from appropriate drying agents under argon…

In this week problem, the students are presented with a table with data on altitude and temperature gathered by a weather balloon. The data is in the first column shows the data of the altitude in feet, and the second data shows the air temperature in degrees Fahrenheit. Part A asked the students to pretend that they are making a comparable metric table of the data with the same variables. The altitude need to be change into kilometer and the temperature is measured in degree Celsius, what is…

Tin is a Chemical element its symbol is Sn. Its location on the periodic table of elements is period 5 group 14. Its atomic number is 50 and the atomic weight is 118.71. It has 50 protons, 50 electrons, and 69 neutrons. Tin is a solid, ductile, malleable, silvery-white metal. Tin melts at a low temperature of about 232 °C (450 °F). Tin resists corrosion from water, but can be attacked by acids. Around 5000 years ago, humans first began mining and incorporating tin with copper to create bronze…
