1. a. My data demonstrated the law of conservation of mass in part 5 of the experiment, dissolving sugar in water. The law of conservation mass states that matter cannot be created or destroyed by can enter or leave the system. The system’s change in mass was 0.00 grams, resulting in support of this statement. The balance had an uncertainty of 0.05 grams.
b. With this experiment, we had a closed environment within the vial, not allowing any particles to come in or out, further explaining why there was no change in mass. The experiment also did not cause a visible reaction. The system was the vial, cap, water, and sugar.

c.

2.
a. My data failed to support the law of conservation of mass in part 3, the melting of ice. Our group

    Alka Seltzer Lab

    The purpose of this lab was to understand the Law of Conservation of Mass and how it works, using half of an Alka-Seltzer tablet, concealed in a water to fill the container, while a balloon sealed the top to keep it a closed system. The hypothesis was, if the Alka-Seltzer chemical reaction is a closed system, then the mass of the products will equal the reactants. The data did not support the hypothesis because the products were almost always a different mass to the reactants but only the last trial revealed that the mass of the reactants was equal to the products. Usually, the trials indicated a loss of mass until the third trial was done, which was a success. Since the experiment was a closed system, matter could not leave or enter.…

    In the experiment, I tested how soapy water would affect the amount of droplets the penny can hold. The results of my experiment show that the penny holds less droplets of soap water. When the soap is added to the water, the soap collides with water breaking down the tension. As a result, it harder for the droplets to hold together. To find whether my hypothesis was right, I did several of trials to figure out whether my hypothesis was correct.…

    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 the solution.…

    The authors created the Accelerated Sensor of Action Potentials 1 (ASAP 1) using a green fluorescent protein source on the extracellular side of the plasma membrane to highlight the membrane potential changes as demonstrated by the fluctuation in the fluorescent brightness. Neuronal action potentials generated are monitored up to 200 Hz in frequency using this device. The general purpose of this experiment was to further understand information processing in the brain and how brain activity is affected by electrical activity between neurons. A genetically modified indicator of this kind can provide a real time account of how the chemical signals are being received by the membrane and translated into action potentials during depolarization. Advancements in this field of representing membrane potential changes could lead to improved treatment for a variety of disorders affecting brain tissue and regulating electrical impulses between neurons.…

    The guiding question is that which changes are examples of a chemical change and which are examples of a physical change? Our claim is that 100ml water mixed with salt paraffin wax melting are examples of physical change. While magnesium strip heated, sodium hydroxide and copper chloride mixed and hydrochloric acid added to sodium bicarbonate are chemical change. For task 1, we measure 100ml of water, weigh 5g of table salt and mix the 5g of salt and 100ml of water.…

    Truc-Nhi Do Separation of a Mixture The purpose of this lab was to separate a mixture, calculate the percent composition by mass, and find percent error. I first started out by taking the mass of each component of the lab. I used the infiltration method to allow the salt and water solution, a blended mixture, to pass through the filtration paper and into the beaker. A trick to know if something is a solution is to see is it has the aqueous sign (aq) in the formula, like NaCl(aq).…

    In this lab, we carried out a variety of reactions using different chemicals and metals. A chemical reaction is when the chemical state of the substance you are testing rearranges its ionic and molecular structure. One of the reactions we experienced was single replacement, this consists of one ion switching places with another ion to form a new compound. Another reaction we saw was double replacement. In this reaction, two compounds ions are switched to form two new compounds.…

    After putting each compound into the blended meal, then it was determined whether it contains organic or inorganic in it. The bacon ranch salad reacted negatively to the solutions. While also being tested on a well-plate and hot-plate, it still remained the same color. Therefore, the blended mixture does not contain any organic substances such as protein. We began our experiment by gathering our materials and began to test the change in the blended mixture by putting a small amount in well plate and putting the same amount of water in the container next to it.…

    Homeostasis is maintained when a cell reaches equilibrium inside and outside the cell, equilibrium is when the cell balances equally creating a stable environment. This is an important factor for living things because if there isn’t a stable environment this would have a negative effect on the body. A plasma membrane is important to this process it lets things in and out of the cell, the plasma membrane is selectively permeable which means that it only allows certain things inside and outside the cell. Diffusion releases molecules from high concentration to a low concentration, osmosis is another form of diffusion but deals with water the molecules move from a high concentration to a low concentration. The goal of this investigation was to test if the cell gains or loses mass after coming into contact with alcohol after a period of time.…

    Purpose Of A Sludge Lab

    • 1 Pages

    The purpose of this lab was to use the knowledge gathered this year about chemical and physical interactions, mixtures, and single substances to separate a “sludge” into its components while demonstrating the Law of Conservation of Mass. Scientist determine the substances in an unknown mixture by looking at their chemical and physical properties and characteristics. It can be determined that one substance in the mixture was wood, because a characteristic of wood is that it floats, which the substance did. A physical property is a property of an element that can be seen without changing it. To observe a chemical property, a chemical reaction must be involved. In this lab, mostly physical properties were used in determining the substances.…

    Purpose: The purpose of this experiment was to illustrate how to determine the density of a liquid and regulate volumetric glassware properly. To determine the mass of liquids using a scale, the density of water and (unknown) liquid D were weighed, inside of a volumetric flask. Once the mass was determined in grams, the density was easy to determine, by using the density equation. The second portion of this experiment was to calibrate a 10mL pipette. Once the density was determined for this section, the pipette volume could then be determined, regarding the amount.…
