Science 11
SEMESTER 1
PROJECT
We are making a mole for this project and writing an essay about the use and significance of stoichiometry in business and the manufacturing of goods. Finally, we must compile a table listing the masses of all the materials we employed as well as the total mass of the mole. We determine the percentage error between them based on that. My creative thinking has improved as a result of this project, and I now understand why there is a percent error.
*Our mole base was inspired by the mermaid.
LAB REPORT
Double Replacement Reaction
As you can see above, we perform the double replacement reaction for this reaction when we use KI to react with Pb(NO3)2 to produce PbI (precipitate) and KNO3. It indicates that we are interested in how the reactants' positions change and whether the element survives the reaction.
Hydrate
Heat a known mass of the hydrate to drive out the waters of hydration, then weigh the anhydrate mass that is left over to measure the percentage of water in the hydrate experimentally. The difference between the two masses represents the mass of water lost. A hydrate is located on the left, and an anhydrate is located on the right, as shown in the diagram.
Silver Jar
In this experiment, potassium hydroxide, D-glucose/dextrose solution, and M silver nitrate solution (AgNO3) are combined to create silver diamine ions. The reaction's color changes from white to black and then back to white when ammonia is added. The bottle must then be quickly shaken until a silver layer envelops it, as seen in the picture. I also discover that it was an outdated technique used to create mirrors in the past.
Fussy G' parents Tea
We want to demonstrate how stoichiometry is used in this reaction to make a milk tea. Sugar, water, and tea make up the ingredients. The next step is to weigh everything proportionally. Then, everything is combined in a beaker.
Chromatography
We color pieces of paper for this experiment using a variety of colored pens. We then submerge them in water to observe how the color ages. The experiment has altered the colors of the pens, despite the fact that they are all blue. Additionally, the gradual movement of the water until it covers the entire sheet of paper serves to illustrate how water collides in this experiment.

SEMESTER 2
Scientist Poster
In this project, we design a unique periodic table based on our personal interests. Yuki and I decided to research well-known billionaires because we care about them and are interested in how they became wealthy. The atomic mass in this case is the net worth of billionaires, and different groups of billionaires with different ages and net worths were selected. According to our trend, the age will rise as we move down, and as we move from left to right, the net worth will rise.

GASES LAB
I am aware that when we alter volume, temperature, and pressure, the behavior of the gas alters. These characteristics relate to the typical kinetic energy of the gas molecules because we alter them. The average kinetic energy will vary depending on the change.
Gases Laws summary:
Boyles's Law: pressure is inversely proportional to the volume
P1.V1=P2.V2
Charles's Law: pressure is directly proportional to the2. temperatures
P1/T1=P2/T2
Gay-Lussac's Law: volume is directly proportional to the temperature
V1/T1=V2/T2
