Diction is the precise choice of words and style of expression used by an author. The use of diction is observed multiple times in the short story A Temporary Matter by Jhumpa Lahiri. In A Temporary Matter, married couple Shoba and Shukumar experience the loss of their newborn baby during childbirth. The fatality of their child results in their marriage to slowly deteriorate and eventually cease. The conflicts within their marriage are perceived to be the result of a communication barrier; however, Lahiri's use of diction reveals they are experiencing greater conflicts. Diction has the capability to deliver powerful messages to readers; such as the concept that Shoba and Shukumar’s marriage is in a state of war.
The hypothesis that was formed in this experiment was that decantation and distillation were the techniques that would be successful in separating the three layered substances. The oil on top of the mixture was to be decanted solely, and the salt and sand layers would be distilled and separated together on filter paper on top of boiling hot water. The reason that the oil is decanted is because it doesn’t mingle with the salt and sand layers, and in addition it was the top layer, which was thought to have been easy to separate first. And as for the sand and salt, sand doesn’t mix and dissolve in water compared to salt, which does in fact dissolve, so distillation was thought to be the proper solution to separating the two
A: The reaction with water and vinegar was the most useful in this experiment. The physical properties were very self explanatory because the texture of the powders was all different expect icing sugar and cornstarch. Also the Ph levels were very similar of six and seven for corn starch and icing sugar respectively. d) Q: How confident do you feel about your identification of the

1. Explain the differences between operating budgets and capital expenditure budgets. How are they used?

Investigating the Effect of Drop Height on the Depth of Sand Aim: To investigate the depth of the sand depending on the height at which the ball is dropped from. Variables: Independent variable chosen: The height at which the ball is dropped Dependent variable chosen: The depth of the sand after removing the fallen ball from it. Constant variables and how they will be controlled: Variable How we will keep it constant Amount of sand We leave the sand in the bucket and make sure that none spills over. Type of sand Use the same one for each trials Ball Use the same ball for each trial, with the same size, volume, material and brand.
Chromatography is the laboratory technique for separating mixtures into their components for analyzing, identifying, purifying or quantifying the mixtures or components. The mixture dissolved in the mobile phase (gas or liquid) is passed through the stationary phase (liquid or solid), which separates the analyte from the other molecules in the mixture. The differences in the migration rate of the compounds in these two phases effects the separation.
While traveling through the park, I observed a White colored box truck. The vehicle was backed in between two trees facing North. Furthermore, there was a teal Ford pickup approximately 20 feet from The Ford was also parked and facing West.
The crew doesn’t have an official place they call “Home” such as a football stadium for football. This is mostly because they travel to different races every weekend; however, they do use...
Have you ever stopped and thought, “ what would i do if my kid had a disability?” Or ever question why you act a certain way or if you 're strong enough? In the Articles “Notes From a Dragon mom, What we hunger For and the speech “ This is Water” These authors all share there thoughts on what makes a person act the way they do.
The simplest experiment for this type of situation would be to use red and blue litmus paper to distinguish between acids, bases and salts. Hydrochloric acid (HCl) makes blue litmus paper change color going from blue to red, making it an acid. Sodium hydroxide (NaOH) makes red litmus paper change color going from red to blue, making it a base. Sodium chloride solution (NaCl) is neutral, since it would only soak blue and red litmus paper, considering that it is a by product of when an acid and a base mix together, neutralizing each other.
Saferstein lists the three forms that fall under: solid, liquid, and gas. “A solid is rigid and therefore has a definite shape and volume. A liquid also occupies a specific volume, but its fluidity causes it to take the shape of the container in which it is residing. A gas has neither a definite shape nor volume, and it will completely fill any container into which it is place” (2011, Pg. 120). Chromatography, spectrophotometry, and mass spectrometry are used to identify or compare organic materials.
It’s race day and life in the pit crew is like being a goalie, 99% boredom and 1% panic, working 12 hours a day every day. When I arrived at LOWES motor speedway in North Carolina, everyone was in this 99% boredom phase, or their “down time”. It’s 7 a.m. and the cars of each team sit in the one story tin garage building with unfinished concrete floors looking almost like it was temporary, halfway equipped for the upcoming race and surrounded by their respective crewmembers. As I walk through the inside of this garage, big enough for twenty-five cars but filled with about fifty cars, the walking paths are carved through the clutter of race cars, roll-a-ways and loose parts. It is right to say that it is crowded. The U.S. Border Patrols pit crew had to prepare for any possible mishaps on the track. Working on and off throughout the day wanting the car to be as safe as possible but also try to exceed the natural laws of physics.
Since the days of Aristotle, all substances have been classified into one of three physical states. A substance having a fixed volume and shape is a solid. A substance, which has a fixed volume but not a fixed shape, is a liquid; liquids assume the shape of their container but do not necessarily fill it. A substance having neither a fixed shape nor a fixed volume is a gas; gases assume both the shape and the volume of their container. The structures of gases, and their behavior, are simpler than the structures and behavior of the two condensed phases, the solids and the liquids
