Abstract: A 50mL (we used 100mL) volumetric flask was used to determine the amount of sugar in a can of Coke per mL in 5 different solutions. Using the calibration curve we determine the amount of sugar per mL in a can of coke. This experiment concluded that there is 43.83g of sugar in a 12oz can of Coke.…

In order to prove this, I conducted a lab to determine the solubility, conductivity, and melting point of each substance. First, I made sure to obtain a Bunsen burner, evaporating dish, ethanol, the four substances, distilled water, conductivity probe, wash bottles, test tubes, and a beaker. I made sure the materials were cleaned to…
Materials and Methods: I first pulled out the small wells and place two drops of the Cobalt (II) Nitrate in seven of the wells. I then moved to the next row and placed two drops of Copper (II) Nitrate in the next row, into seven of the wells, and so on with the other three Nitrates. I then cut off the top of the Sodium Phosphate and added two drops to the Cobalt (II) Nitrate and observed the reaction and recorded the results. Then two drops into the Copper (II) Nitrate, observed and recorded, same with the remaining three Nitrates. I then moved to the second row, and place two drops of Sodium Iodine into each of the five nitrate wells. I repeated these steps with all seven Sodium compounds. I observed and recorded after each combination. Below are my results:…

In The Laboratory, the courtesan chooses poison as her murder weapon. Poison is often the weapon of choice for female killers. It requires little or no physical strength to administer, and can be done secretly. It also leaves little evidence thus making it difficult to detect the culprit. We believe the act of murder is because of another woman that her lover is with and she feels physically inferior to her rival. We know this because she starts saying ‘What a drop! She’s not little, no minion like me.’ The murderer is also fascinated and excited about the poison and power of the poison, she says ‘And yonder soft phial, the exquisite blue sure to taste sweetly’ She thinks that her rival who she is out to kill will think nothing of it and will believe it’s just an ordinary beverage. She then also goes onto say ‘to carry pure death in an earring, a casket.’ Meaning she is so excited about the whole aspect of being able to carry death in such a small item. So she plans to slip her rival only known as ‘Pauline’ and give her thirty minutes to live until ‘her breast and her arms and her hands should drop dead!’ This is what she believes will happen in her head, she believes the murder will happen quickly and she also chose poison because she didn’t want to see it happen. Browning writes ‘The delicate droplet, my whole fortunes fee’ showing that she’s incredibly dedicated in getting this guy and she’s spent her whole fortune on the poison and she’s not going to give up until the deed is complete. The character is quite evil in a way; not only has she murdered someone but she says ‘ Not that i bid you spare her the pain; Let death be felt and the proof remain; Brand, burn up, bite into its grace- He is sure to remember her dying face!’ Which is almost saying that he is going to remember this moment for a long time and this is her perfect revenge on him for leaving her for this other woman. The character is also quite optimistic about the whole thing as she doesn’t feel…
Density is one of the fundamental principles of physics. Density is the reason why a plank of wood floats on water while a piece of metal several times smaller will sink. Density of an object is measured in g/cm³ or g/cc. The equation is D=M/V, D being the density of the object, M being the mass of the object, and V being the volume of the object. Mass is the space an object takes up. It is the amount of matter present in an object. Mass is measured using a triple beam balance. Units used to measure it are grams, metric tons , milligrams , and kilograms . Volume is the amount of space enclosed by a shape or object, how much 3-dimensional space it occupies. It can be occupied by a solid, liquid or gas. The volume can be measured in cubic meters, cubic centimeters, or liters.…
