Pressure in Popcorn Lab

Image
1-4) calculations, conversions, and formulas used are all listed above. found our total pressure was 21.3 atmospheres. initial mass was .0033 mole of H2O. 5. The atmospheric pressure we receive daily throughout our lives is constantly around us while the pressure of the water vapor in the kernel was trying to escape and the pressure on the kernel eventually could not endure any more and became popcorn 6. I believe not all the kernels popped due to differences in the amount of water in the kernel, the more the water the easier it was to pop but the kernels with less water had a harder time to pop 7.A potential error for this lab could be the exact temperature at which the kernels popped because if kernels pop at different times there can be differences in temperature.

Hall of Fame event EC

The Bellarmine Hall of Fame Event was a very special experience that i am very grateful to have witnessed. The Hall of Fame honors former Bell graduates who have excelled as athletes, scholars, business men, men of fine arts, science/ medicine developers or men who have taken a big role in serving our community are given the chance to celebrate their accomplishments. For me it was inspiring to see former Bells come back to the community to inspire and share their accomplishments/ knowledge with current Bellarmine students. Each and every person nominated clearly showed ignation values and acted as men for and with others. Truly inspirational and i am grateful to have had the chance to come to this event. Someday i hope i can be up there just like them.

mentos

the chemical reaction that takes place when dropping a mento into a bottle of soda is called nucleation. What causes the pressure is the build of carbon dioxide in the plastic container of the coke. Boyles law can be used to explain this because there is a build up of pressure which caused the bottle to fly up into the air. In my opinion the reason why the bottle flew up was because of the drastic increase in pressure.

Limiting reagent lab

Image
 1. What are the limiting and excess reagents for each flask? How did you determine this? the limiting reagent was the sodium bicarbonate because during each test it was completely used. while the excess reagent is the vinegar because there was always some vinegar left. 2. How is the amount of product in a reaction affected by an insufficient quantity of any of the reactants (reagents)?  The amount of product is reduced because if there is an insufficient amount of any of the reactants then only so much of the final product can be made until there is only one of the reactants remaining. 3. Which balloon was the largest? Explain. The largest balloon was the purple balloon because it had the largest volume from pouring in the most sodium bicarbonate which caused a reaction that produced the most CO2 filling the balloon  4. Which balloon was the smallest? Explain. The blue balloon was the smallest because in contrary to the purple the lest amount of sodium bicarb

electrolytes and conductivity lab

Today in chemistry, we used pennies, a vinegar-water-salt solution, matboard to construct a battery to power an LED light. We started by first collecting five pennies and shaved the copper off of the tails side. We then created a vinegar/salt solution in which we dipped the matboard into. To construct our battery, we would place a penny shaved side up, then place a soaked piece of matboard on top of it. Finally we placed an unshaven intact penny at the top of the stack and place an LED on each end of our battery. Our end result lit up, causing us to then question the factors that caused this. for example, we placed more pennies onto the battery which ultimately made the LED light up brighter. In this lab I think that the solution soaked onto the matboard was a source of chemical energy and conductivity through acetic acid, sodium, chloride, and water, which was converted into an electrical current and passed through the pennies zinc and copper makeup, then finally through the lea

Reactivity of Metals

Sodium Calcium Lithium Start color for all elements All elements total  Aluminum and Magnesium Analysis - From this lab I learned that different elements have different reactions when placed in an acidic solution. Sodium and Lithium reacted the fastest quickly changing the color from an acid which is red to a base which is the color blue. The other 2 elements, Magnesium and Calcium took much longer but eventually turned the red liquid to blue. Aluminum never turned from red to blue.  What causes this reaction is when an element is placed in the acidic solution causing it to loose one of its valence electrons. What went wrong - first the lab took a very long time to actually record all the results a total of three days. Second the lab was very dangerous. Third there was unmeasured amounts of each element throwing off some of the accuracy.
