Formula and Percent Composition of the Compound Magnesium Oxide (MgO) Nice sounding title Date Performed Lab: 8/31/06 Purpose: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner in a crucible. Using molar masses of both magnesium and oxygen‚ an expected percent composition

Albert Einstein supposedly once said “Everyone is a genius.” What he was trying to point out to us is that no matter what subject or issue‚ everyone has a talent where they excel‚ and (Coordination) in which they are classified as a genius. But what exactly is a genius? The dictionary states it as an exceptional natural capacity of intellect where intellect is the power or faculty of the mind by which one knows or understands. However‚ there can be various types of geniuses: of the arts‚ inventors

Determining the Limiting Reactant and Percent Yield in a Precipitation Reaction Objectives: Observe the reaction between solutions of sodium carbonate and calcium chloride. Determine which of the reactants is the limiting reactant and which is the excess reactant. Determine the theoretical mass of precipitate that should form. Compare the actual mass with the theoretical mass of precipitate and calculate the percent yield. Materials: Balance 0.70 M sodium carbonate solution‚ Na2CO3(aq)

In the late 1880’s Nikola Tesla and Thomas Edison battled over what type of electricity {Alternating Current or Direct Current} would become standard in the United States (Nix). People today take electricity for granted‚ but during this time period people were just beginning to dawn the idea of having electricity in households. The vast majority of people had to utilize more dangerous types of electricity such as gas lamps. Nikola Tesla and Thomas Edison both invented a type of electricity and the

Acetic acid is monoprotic and belongs to the carboxyl family of organic compounds. The titration method is used to neutralize the acids by using the standardized sodium hydroxide solution. It reacts with

Determining the Limiting Reactant and Percent Yield in a Precipitate Reaction (SMG 6D) AP Chemistry One example of a double replacement (metathesis) reaction is the mixing of two solutions resulting in the formation of a precipitate. In solution chemistry‚ the term precipitate is used to describe a solid that forms when a positive ion (cation) and a negative ion (anion) are strongly attracted to one another. In this experiment‚ a precipitation reaction will be studied. Stoichiometry

How do you obtain inspiration on theater? What do you think inspiration means? ‚ Inspiration is an emotion when you love something and you do it because you like how it feels? Or is it something that promotes you to do something? Well its a little of both‚ its not an emotion its a feeling that promotes you to do something. But‚ how do you obtain inspiration? Is it different to obtain normal inspiration and inspiration on theater? You only obtain inspiration if you like something and if it is

Analysis of the Biography "Edison" by Matthew Josephson Matthew Josephson does an excellent job of covering all the aspects of Edison’s life and career. He portrays Edison as both a great scientist and inventor‚ but also gives the reader a look inside his personal life. Aside from writing about Edison’s life works‚ Josephson also tells us of Edison’s boyhood‚ home life‚ and finances. He even speaks of Mr. Edison’s relationship with Henry Ford. Josephson remains objective as he describes

The Inspirations Edgar A. Poe finished the last line of ‘The Tell-Tale Heart’ with a flourish. “Now to put them onto clean sheets of paper”‚ he said looking at the blood stained pages. “And of course‚ put away the body.” This was directed to the body of Mr Harper which slumped next to the desk. He gripped the body by the legs and thought with pleasure of his new deeds and the new novel which rose from it. He dragged it to the cellar next to the bodies of Lady Lenore‚ Mr Roderane‚ Mrs Magdalene
