The reaction between sodium thiosulphate and hydrochloric acid forms the word / chemical equation below: sodium thiosulphate + hydrochloric acid -> sulfur dioxide + sulfur + water + sodium chloride Na2S2O3 (aq) + 2HCl (aq) -> SO2(aq) + S(s) + H2O(l) + 2NaCl (aq) When sodium thiosulphate reacts with diluted hydrochloric acid, a mixture of…

could easily colonize the galaxy. Nevertheless, with no physical relics, chemical traces, or biological influences suggest the existence of any alternate life form, many may assume that there is not intelligent life beyond Earth. Beyond the Drake Equation and much speculation from the scientific world, no evidence suggests that extraterrestrials have visited Earth or have attempted communication. Without any evidence, accordingly, scientists assume that the resolution of the Fermi Paradox must…

1. Iodide proved to be the more reactive nucleophile in this reaction. This nucleophile was faster than Chloride, because on the periodic table, Iodine has a bigger atomic size, while Chlorine has the higher electronegativity, but size trumps electronegativity, as according to ARIO rules. This means that Iodine is more acidic than Chlorine, which means that in the reaction, the Iodide could displace the Bromine from the 1-bromooctane, because it has a bigger size, much faster than the Chloride,…

Chemical change is any change that results in the formation of new chemical substances. Chemical changes take place on the molecular level. Another way to think of it is that a chemical change accompanies a chemical reaction. To find if a Chemical Change is occurring you need to determine whether a new substance has formed because of the change. If a new substance has been produced, then a chemical change has occurred. The new substance formed in a chemical change could be a solid, liquid or…

The solution of the Frank and Doris race problem looked to be simple at first. Although Doris speed began faster, Frank gained speed and passed her and thus seemed to be the winner of the race. After looking more closely at the problem I discovered this was not quite the case. I first sketched Frank and Doris given values onto the one Velocity-Time graph. Originally looking at this graph, it looks as if Frank passes Doris at 10 seconds, because that is when his speed becomes greater than Doris’s…

Aim: - The aim of this experiment is to find out on how the independent variable which is the temperature changes that reaction rate of the magnesium and hydrochloric acid (HCI). Hypothesis: - As the concentration increases, the rate of reaction increases as well. Variables: - The independent variable is the volume of hydrochloric acid - The dependent variable is variable is the volume of the hydrochloric acid and the duration of reaction. - The controlled variables are length of the strip of…

Mood in the Cold Equations Sometimes, even the most innocent and smallest of mistakes can have a drastic effect on things. Since space is pretty much the full extent of human exploration, small mistakes almost always have a very drastic effect. In the short story “The Cold Equations” by Tom Godwin, he creates an intense and tragic mood, by foreshadowing the inevitability of Marilyn’s death, even when she was innocent and…

(2) through transposing Eq (2) The activation energy was found from the following equation E = 8.314 * slope (3) The activation energy values were later used for computing the pre-exponential factors (A) by equation (1). In the meantime, activation energies (Ea) for these energetic compounds were calculated by the Ozawa method. The Ozawa equation according to ASTM E698 is equal to the following…

A rate law is an equation used to determine how much the concentrations of solutions will change as times goes on. In this experiment, the rate changed based on the five degree Celsius temperature change and concentration change in three different reactions. In this lab,…

All the scenes in the play were short and barely any characters were called by name. They also did not go in order of the pamphlet that spells “Shakespeare.” Throughout my paper, I try to describe each scene to the best of my ability with the info of which play they are acting out or about just the scenes in general. The beginning of the play began with people cleaning up the stage with brooms. The three people were slouched over sweeping close together. This showed medium topography and close…
