Limiting reagent lab








 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 bicarbonate was placed inside during this reaction, thus producing less CO2 making the volume of the balloon the smallest.

5. Rust is produced when iron reacts with oxygen. How many grams of Fe2O3 are produced when 12.0 g of iron rusts?4Fe(s) + 3O2(g) → 2Fe2O3(s)  6 grams of Fe2O3 are produced when 12 g of iron rusts.

6. What real-life applications can this concept of limiting and excess reagents be applied to? when building a car you need 4 tires + 2 head lights= 1 car. You need this exact amount of products to make the final outcome which is the total car.

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

Intro to Chemistry

1)  Chemical changes through chemistry can be seen in our daily lives. (For example, a piece of bread turning to mold, or milk turning souring.) Its very interesting that basic everyday things around us are causing chemical reactions, 2) I found it very impressive that they are more than five types of chemistry including, physical chemistry, organic chemistry, inorganic chemistry, analytical chemistry, and biochemistry. This opens my eyes to how large the world of chemistry is. Organic chemistry- is the study of chemicals containing carbon.  inorganic chemistry- the branch of chemistry that deals with inorganic compounds. Biochemistry- is the study of chemical processes within and relating to living organisms.   physical chemistry- the branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems. analytical chemistry- studies and uses instruments and methods used to separate, identify, and quantify matter.  3)
