enrolled in an Investments class has picked a project on bond price theorems. The two main theorems that she decided to illustrate dealt with coupon rate and term-to-maturity and how these factors influence the price. Thus she included 2 bonds with the same rating and term with a different coupon rate‚ as well as two bonds with the same rating and coupon rate with different terms. She thought that if the bond markets were efficient‚ bonds with similar characteristics would be priced so that there

is to learn to demonstrate a double-replacement reaction of ionic compounds. To accomplish this‚ two ionic compounds will be mixed together and the product will precipitate out of solution. In this procedure‚ the product must be precipitated out of the solution and then weighed. For this lab‚ lead (II) nitrate (Pb(NO3)2) and potassium chromate (K2CrO4) will be reacted together to demonstrate double replacement reaction between 2 ionic compounds. This was shown when chromate replaced the nitrate

a much more polar molecule than 2-propanol. How does the polarity of the liquid seem to influence the solubility of these solids? Water is more of a polar molecule then the given 2-propanol which allows ionic soild‚ sodium chloride that breaks off and becomes soluble. Camphor is not an ionic solid which means that it is not soluble in water although of the given molecular polarity. 9.

and melting point. Some substances came very close to passing all the tests‚ but only one substance was able to pass all of them. I recommend using sodium carbonate as your substance. Of all the substances‚ only two were covalent and two were ionic. The ionic substances‚ sodium chloride‚ sodium carbonate‚ and salicylic acid‚ came close to the description you requested. The covalent substances‚ sucrose and salicylic acid‚ did not match the descriptions. The best substance would definitely be sodium

Under strong electrolytes we have NaCl and CaCl2 which are ionic compounds‚ HCI‚ HNO3‚ HBr and H2SO4 are under acids and NaOH‚ KOH‚ and LiOH are under bases. Weak electrolytes are ionic compounds and slightly soluble such as CH3COOH‚ under acids we have HF‚ H2CO3‚ H2SO3‚ and NH3.While nonelectrolytes are nonpolar covalent compounds such as O2 and H2O‚ and under acids we

In a single replacement reaction there is typically a metal and an ionic compound consisting of a metal cation and a non-meatl anion. Singel replacement ractions occur when the reacting element is more active‚ whihch means it is more likely to lose electrons than the product element. There was two parts to this experiment‚ in Part A we mixed various aqueous solutions of ionic compounds and observed

Problem How can the understanding of colligative properties be applied to making ice cream? Hypothesis Adding salt to the water lowers its freezing point (freezing point depression‚ which is a colligative property). The water will now stay liquid at lower temperatures‚ which is required to make ice cream. Procedures 1.

In the case of bankruptcy‚ bonds generally provide more safety than stocks. You can read more about why here. Bonds vs. Stocks: Lender vs. Shareholder When you buy a stock‚ what you are buying is a small piece (or a large piece if you are someone like Warren Buffet!) of ownership in a company. As an owner you have special privileges‚ including the ability to vote on matters that affect the future of the company. More importantly however‚ is the fact that as a stockholder you have the right to

Home Products stock and bond valuation HOME PRODUCTS - Case 9 STOCK AND BOND VALUATION In all textbooks‚ the valuation of stocks and bonds is simply stated as the present value of all the future cash flows expected from the security. The concept is logical‚ straightforward‚ and deceptively simple. The valuation of bonds is usually presented first‚ since the relatively certain cash flows are broken into an annuity and a payment of the par value at some specific date in the future.
