Lab 10: Mole-Mass Relationships Lab

   The purpose of the Mole-Mass Relationship Lab is to further understand the mass to mass relationship in a chemical equation and interoperate the balanced chemical equation. During the lab, we were required to heat NaHCO3(s) + HCl(aq) which yields NaCl(aq) + CO2(g) + H2O(g). In this process, a chemical reaction of bubbling occurs when the hydrochloric acid is added to the sodium hydrogen carbonate. After this, water is added and the mixture is boiled. The water evaporates out and NaCl( sodium chloride) powder is left.


1. Which reactant is limiting? How do you know?
   The limiting reactant is the NaHCO3. There is a limited amount of NaHCO3, so there could be remaining HCl( hydrochloric acid) if extra was added in.

2. Find the theoretical yieald of NaCl based on your limiting reactant. Show your work below.
3. Find the mass for the reaming solid product after the evaporation of water based on your experimental data.

4. Find the percent yield for the experiment for the solid product. 
The product yield is over 100% because all of the H2O (water) did not evaporate out.

Lab 11: Flame Test Lab

Image
   During the Flame Test Lab,  metallic ions were burned and vaporized to exhibit specific colors. Nine solutions and two unknown solutions were burned and displayed colors ranging from pink to blue. Pre-Lab Questions 1. What is the difference between ground state and excited state?    When an atom is in its ground state, it is in its lowest but stable energy level. When an atom is in its excited state, an electron has jumped from its orbital level to another one. 2. What does the word "emit" mean?    Emit means to produce or release something. 3. In this experiment, where are the atoms getting their excess energy from?    The atoms are getting excess energy from the heat. 4. Why do different atoms emit different colors of light?    The atoms emit different colors of light because the energy that was absorbed from the heat emits electromagnetic radiation at different wavelengths.

Lab 4: Atomic Mass of Candium

Image
   The purpose of the Atomic Mass of Candium lab is to determine the average atomic mass of the element candium. The lab requires the measurement of the mass for each isotope of candium by using a balance. Then the samples of each isotope has to be individually counted. The average mass of each isotope is then calculated by dividing the total mass by the total amount of each isotope. Next, the percent and decimal abundance is determined. Finally, the average atomic mass is calculated by using the formula. The average atomic mass comes out to 1.1g Conclusion Questions 1. Ask a group nearby what their average atomic mass was. Why would your average atomic mass be different than theirs?     The average atomic mass of the other group was 1.053 g. The mass is different because our grouop has different amounts of each isotope compared to the other group. 2. If larger samples of candium were used, for example if I gave you a whole backpack fil...

Lab 1: Density Block Lab

Image
In the Density Block Lab,  the purpose is to calculate the mass of the block of material. This experiment consists of finding the mass of a cubic block  by multiplying the density and the calculated the volume. The lab concludes with comparing the experimental mass with the mass the instructor calculated. The experimental mass is compared with the actual mass to calculate the percent error.  Density is the amount of mass per unit of volume. Mass is the amount of matter in an object. Volume is the quantity of three dimensional space taken up by an object. Significant figures is each of the digits of a number that are used to express it to the required degree of accuracy. The equipment used in the lab are a ruler and a balance. The material needed for this lab was a cubic block of an unknown material.  First, the volume of the block was calculated by measuring the length, width, and height. Next, the mass was determined by multiplying the volume, 13.834 cubic cm, b...
