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.
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
Based on our observations during the separation techniques and some speculation, we were able to identify eight components of our mixture: graphite from the filtration residue, Epsom salt from crystallization, water and acetic acid through distillation, red and orange dye, iron metal, marble chips, and sand.
1. Explain the differences between operating budgets and capital expenditure budgets. How are they used?

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.
A mixture, according to definition, is a combination of components and substances mixed together to form one particular substance, uniform or not. Mixtures can be classified down to two types, homogeneous and heterogeneous. Homogeneous mixtures are generally uniform, or have the same consistent composition throughout, whereas heterogeneous mixtures are not entirely defined and vary in
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 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...
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.
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 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.
Solids are more stable than liquids and gases. One type of solid is a Crystalline solid. The particles in a crystalline solid have a regular repeating pattern. The types of crystalline solids are metals, alloys, salts, valence crystals, molecular crystals, polymers, and plastics.
