Na3po4-6 Lab Report
The identities of cations and anions were determined by using solubility rules for ionic compounds. The mixing of solutions was classified if precipitate was present or absent. Cation A was determined as Ag+ and formed a precipitate in NaBr-, NaOH-, and Na3PO4-3. Cation B was Ba+2 because it formed precipitate in Na2SO4-2 and Na3PO4-3. Cation C was classified as Cu+2 not only because the solution was blue; but also it was insoluble in NaOH- and Na3PO4-3. Cation D was found as Fe+3 for its rustic color and insolubility in NaOH-, Na2SO4-2, and Na3PO4-3. Cation E was determined as K+ because it was soluble in every anion solution. Cation F, Mg2+, was only insoluble in Na3PO4-3. Pb+2, Cation G, formed precipitate in every anion solution. Anion

    What are the factors that lead to evolutionary change? Using mathematical equations, Hardy & Weinberg in the early 20th century showed that evolutionary change – measured as changes in allele frequencies in a population from one generation to the next – will not occur unless certain kinds of “evolutionary agents” are affecting the population. The Hardy-Weinberg equation can be used to describe the allele frequencies in populations that are not changing evolutionarily – and also can be used to determine if populations are changing over time.…

    To determine the ionic compound from compound B and compound C, a conductivity test and solubility test were carried out. Both compounds were mixed with water. Both compounds were soluble in water. Therefore, the type of compounds could not yet be determined. Both solutions were then tested with a conductivity meter. The larger value of conductance of solution of compound C significantly assured that compound C is the ionic compound whereas compound…

    When given two equations the goal is to make the equations equivalent to one another. These two equations are equivalent. Two equations are known to be equivalent if they have the same solution set. A solution set is a set of numbers that that solve an algebraic equation. In the first equation, the solution set is {5}. In the second solution set both sides of the equation must be equal. Equal means that both sides are balanced. The equality of addition property states that each side of the equal sign must have the exact same numerical value. On both sides, we have a which is the same “number” or “letter”. Since 5 is on one of the sides 5 must be on the other side due to the equality of addition property. That makes x {5}. Finally, because both of their solution sets are {5}, we know that the two equations are equivalent because they have the same solution set.…

    The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation, the process in which a cell takes up and expresses a new piece of genetic information, the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their tools, and other supplies for as long as they need, and keep them from touching anything. They must also learn that tools can never be shared between specimens, and when they use a tool, they should dispose of it and get a new one. Next they need to learn how to transfer a bacterial colony. To do this, one must use a sterile loop and scrape one colony off of the dish. Then they must insert the loop into…

    The primary function of the heart is to transport blood throughout the body, which delivers oxygen, nutrients and chemicals to the cells of the body to ensure their survival and proper function and to remove the cellular wastes. For the body to achieve this, it must maintain a certain blood pressure within the body to overcome gravity and orthostatic changes. If the body did not keep a certain pressure, distal cells and organs would not be able to receive a constant blood supply and cause a homeostatic imbalance. This experiment will show the possible changes in blood pressure due to gravity and orthostatic changes, but first, what is blood pressure and why is it important?…
