In the first reaction‚ magnesium was burned to produce magnesium oxide. The reaction produced a bright light‚ which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to

The Yield Curve is very similar to the term structure except that it is based on coupon bond yields whereas the term structure is based on only pure discount bonds. In looking at the current Yield Curve we can see that the general shape is that of an upward-sloping structure. In relation to anticipated future inflation this curve indicates that inflation is expected increase which is evident by the increasing size of the inflation premium wedge that is causing the overall curve to slope upward

P2 2. Judy Johnson is choosing between investing in two Treasury securities that mature in five years and have par values of $1‚000. One is a Treasury note paying an annual coupon of 5.06 percent. The other is a TIPS which pays 3 percent interest annually. a. If inflation remains constant at 2 percent annually over the next five years‚ what will be Judy’s annual interest income from the TIPS bond? From the Treasury note? b. How much interest will Judy receive over the five years from the

Copper-Iron Stoichiometry Lab Report 10/3/12 Abstract: The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate‚ CuSO4‚ mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was

factors. Many believe that it is hard work that bring them success‚ others think that luck is more important. I totally agree with the quotation‚ because I believe that success comes from hard work‚ as Newton said “Genius is one percent inspiration and ninety nine percent perspiration”. People often believe that luck is something that is beyond our control. How can we know when we get a big contract? How can we predict when our experiment give way for a new discovery? I disagree with this kind

Identification of a Copper Compound by Percent Mass Unknown Compound: #9 Abstract: The objective of this experiment was to identify the unknown pure copper salt compound of #9. To do this‚ the mass of copper in the unknown was calculated and then divided by the mass of the whole compound to get the percent copper. The molecular weight was also calculated by dividing mass of copper compound used by moles of compound in unknown sample. The percent copper averaged out to 31.6% while the molecular

CHEMICAL EQUILIBRIUM Reversible reactions and dynamic equilibrium Ammonia (NH3) is an important industrial chemical that is used in the manufacture of fertilisers. It is manufactured by reacting hydrogen with nitrogen. The reaction is said to be reversible and the conversion of reactants to products is never complete. N2 + 3H2 2NH3 A reversible reaction is a reaction which can take place in either direction When the concentrations of the reactants and product have become constant‚ a

The chemical element copper‚ with Atomic Number 29‚ has been extensively used for thousands of years because of several primary properties that have dictated its use throughout history. Among them we can count durability‚ strength and‚ as a semi-noble metal‚ good resistance to corrosion. With a hardness of 3 on the Mohs scale‚ pure copper is relatively soft and malleable‚ which makes it an easy metal to work with. Analyses of artefacts from lithic civilizations have shown that native copper had not
