Double Displacement Lab Report

In this lab experiment our main focus was to get skillful in using tools such as the metric ruler, balances, thermometer, and graduated cylinder to capture measurements of length, mass, temperature and volume. Additionally, this lab helped us to become more familiar with the uncertainty of measurements, as well as becoming efficient with rounding our measurements to the correct numbers of significant figures. Our results are measured consistently with rounding to the closest answer we could possibly acquire as the data can tell you.

The purpose of this experiment is to distinguish the relationships between reactants and products, in addition to expanding on concepts such as single displacement reactions, mole ratio values, moles to mass, theoretical yields, limiting reactants, excess, stoichiometric relationships and percentage errors.

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

2. (5 pts) List and explain the names and affiliations of the various characters/stakeholders in this story – I’m looking for us to use the story to map out the complexities that are generally associated with solving public health puzzles – the stakeholders you list and explain here should apply to many of the cases we consider going forward.

The purpose of this lab is to study some of the physical properties of two types of solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour, hardness, melting point, solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours, hard, a high melting point, soluble in water and insoluble in 2-propanol; some of the physical properties of camphor are a strong odour, soft, a low melting point, insoluble in water and soluble in 2-propanol. A few conclusions can be drawn from these

The purpose of this experiment was to explore the properties of chemical substances that can be used to identify the types of bonds in a chemical substance using a laboratory procedure. The two types of bonds being identified were ionic and covalent. Based on a substance’s properties, how can you determine whether its bonds are ionic or covalent? This is the question I posed before starting the experiment.

The main objective of this experiment is to differentiate between a physical change and a chemical change.

During the last lab, two properties were highlighted to facilitate the experiment. This lab had demonstrated the use of the properties of hydrates and the law of conservation of mass using hydrates. There were four differents experiment which were used to defined the final product. Hydrates being defined as compound were combined with water. Water had played a big role in some part of the experiment.

In this lab, we were introduced a new tool called Dip Trace. We were asked to create a simple schematic and PCB (Printed Circuit Board) by using DipTrace.

The objective of this experiment was to learn how water displacement affected density. Another objective was to identify the metals used in our experiments. We used a variety of different metals to test their correlation and to find out if it was negative or positive. I did not expect to learn much from this experiment as we had already discussed density in class and learned that water displacement is basically volume so as it increased the density would have decreased had we used metals of the same mass.

5 / 10 To prep our purified PCR product and our PCR control for electrophoresis, we added 4 microliters of Blue Juice loading buffer to each sample. The samples were then loaded into the wells of the gel along with a DNA Size Standard. The electrophoresis chamber was then turned on and the voltage setting was switched to high. The electrical current applied to the chamber caused negatively charged DNA molecules to move from the positive end to the negative end, with the smallest fragments moving the furthest.

Title: Separation Lab Purpose: The purpose of this lab was to successfully separate a mixture of iron filings, poppy seeds, sand and salt. Hypothesis: In my opinion, I think it is possible to successfully separate the mixture.

In this experiment, we experimented finding the fundamental quantities of length, mass, and time using many laboratory tools. We used a Vernier caliper, stopwatch, rulerm meter stick, wooden block, metal block, Dial-o-gram, different masses, and circular objects. We took into consideration the uncertainties of many different tools and objects into our experiment. The inherent uncertainties of different measurements and ways to propagate those uncertainties were learned during this experiment.
