During the Roaring Twenties, the government ratified the 18th Amendment, also know as…

The roaring 20’s was an innovative time in American History. New inventions that we still utilize to this day were created. Although we were striving with our excellent creations, we also had many economic downfalls during that decade. Food in the 1920’s was greatly affected by prohibition and the overproduction of produce. The alcohol ban lead to violence and rebellion against the government. Meanwhile the overproduction of food affected the farmer’s quality of life. Prohibition began in 1919…

In the 1800s, many Americans began to drink excessively. This was partly due to economic and social problems that occurred during and after the time of the American Revolution. Alcohol was abused daily. Instead of money, workers were given drinks as a method of payment. It was not long before people learned that alcohol caused health problems such as anxiety, permanent brain damage, and alcoholism. Americans also came to the conclusion that alcohol was the cause of many crimes. There were over…

Aim: The aim of this investigation is to determine the effect of water temperature on the time it takes for an aspirin tablet to dissolve. Hypothesis: The boiling water will have the quickest time to dissolve the aspirin tablet. This is because its molecules have more energy and are vibrating more rapidly than the cold water. Cold tap water will have the slowest time to dissolve the aspirin tablet because it has the least kinetic energy. Why? Apparatus: Equipment: Image Kenwood Kettle Pyrex…

The definition of an accelerant is a substance that accelerates the speed of fire or makes a fire more intense (Accelerant | Define Accelerant at Dictionary.com, n.d.). When forensic laboratories have debris that was collected from a crime scene they can use either the Headspace or the Vapor Concentration techniques to determine if there was an accelerant used. Both techniques use Gas Chromatography, which is separating mixtures based on their distribution between a stationary liquid phase and…

How to make slime Some people know how to make homemade slime but some people always have to search on how to make homemade slime. So here it is how to make homemade slime. The first step, is to Start by filling one of your cups up with water, and stir one spoonful of Borax into the water. Then, put about an inch of glue into the other cup. Add three tablespoons of water to the glue and stir. You can add color (food coloring). If you would like colored slime, add a few drops of food coloring…

The purpose of this lab is to observe the different colors produced by different compounds. My hypothesis is that each compound will produce a different color. For the procedure, we first took a wooden splint and placed it in distilled water. Then, we lit matches we received from Mr. Maloney, and turned on the gas which turned on the bunsen burner. We then took one compound from the front table. We took the wooden splint in the water, and scooped up a tiny bit of the substance and placed the…

The unknown base concentration of a sodium hydroxide solution can be determined by titration potassium hydrogen phthalate (KHP) with an unknown concentration of sodium hydroxide NaOH. The average molarity of NaOH determine by the moles and volume of the KHP and NaOH. (Eq 1). KHC8H4O4(aq) + NaOH(aq) = H2O(l) + NaKC8H4O4(aq) (Eq 1) The unknown concentration of white vinegar can be determined by the white vinegar with the known concentration of…

1. Existing knowledge, research and views: The separation of the sulfur and iron powder was accomplished through magnetism. When combining the sulfur and iron powder to form a mixture, a magnet can be used to attract the iron separating it from the sulfur. Unlike the iron and powder, the salt and sand were separated through filtration. This is a method which separates solids from liquids. In the experiment, the mixture of salt, sand and water are separated as it is poured through a funnel with…
