Experiment #8: Limiting Reactant Abstract In chemical reactions, the significance of knowing the limiting reactant is high. In order to increase the percent yield of product, increasing the limiting reactant, possibly, is the most effective. In this experiment we were able to calculate limiting reactants from the reaction of CaCl2. 2H2O + K2C2O4.H2O(aq). As a group, we obtained our salt mixture of calcium chloride and potassium oxalate, and weighed the mixture. We were able to make an aqueous
The program had to compute y=x^2-x-1 for x = -2 to x=+2 Assumptions made were that a u shaped graph would appear due to the type of equation given. Exercise 3 The problem to be solved in this exercise is to get the Fibonacci sequence in the right order to get the first 50 values. The relationship given in order for us to get the sequence was : “fn=fn-1+fn-2” “f0=0 and f1=1” The program
Charles H. Duell, US commissioner of patents, famously quipped in 1881 that everything that could be invented already had been. It took until 1908 for the first Model T to roll out of a factory. It is a provincial viewpoint that has been around since Ecclesiastes (1:9) that we have reached the pinnacle of our technological game and yet as each new paradigm rolls to a close and our imaginations are saturated with the reality of the world we begin to question whether or not this is the time that the
The initial rate law is used instead. Initial Rate Law utilizes varying the concentration of the bleach and measuring the differing initial rates of reaction and using the rate relationship shown in Equation 5. The variable x represents the reaction order. This concludes that the reaction order of the Commercial Bleach used in this reaction is first-order because the value of x found was 0.913. The percent error of this first order reaction value is
The objective of this experiment was to discover how the concentration of hydrochloric acid affected the rate of reaction in a reaction with calcium carbonate. It was deduced through the experiment that an increase of concentration principally results in a greater rate of reaction. This can be justified through each data point increasing from the previous value, aside from the anomaly when the concentration was at 2 M. The correlation between the two variables was positive. The correlation was not
existence on Earth being the only source of life in the universe is incredibly slim. Organizations such as SETI (Search for Extraterrestrial Intelligence) use math to try to figure out the amount of potential life in the universe with the Drake Equation (Drake).
As illustrated in Table 1, increase in temperature resulted in the increase of the rate of catalase activity to a certain range. After the range, the temperature would continue to increase, but the rate of catalase activity will decrease significantly. Rate of enzyme activity increased as temperature increased is supported by the Collision Theory. The collision theory states in order for a reaction to occur, reacting particles must collide with one another (McGraw-Hill Ryerson Chemistry 12). Particles
IVF Thesis Sentence The cold equation by tom godwin was a story about a girl who snuck onto a ship called the stardust. She strolled away on this boat to see her brother but still aways were not allowed on the ship if they were found they would be jettisoned into space. Summary (1) The stardust witch is the name of a cruiser was a vessel that soared through space, on the side of the cruiser was EDS (emergency dispatch ships) Summary (2) They would only allow a certain amount of people because they
In The “Cold Equation” by Tom Godwin, Marilyn starts of the story as a girl who jumps on a ship to go see her brother who is in war. She is quickly haunted by the news that she will have to sacrifice her life to save the lives of other people. Through Marilyn’s actions and words, she could be described as oblivious, loving, and courageous. Marilyn’s obliviousness to this cold equation adds verbal irony to the story. Marilyn’s obliviousness is seen in this quote when she exclaims, “I was willing
