Shinoda Corp. has 9 percent coupon bonds making annual payments with a YTM of 8.4 percent. The current yield on these bonds is 8
Genrish500 [490]

Answer:

6.33 years

Explanation:

In this question, we determine the NPER or the time period that is shown in the attached spreadsheet

Given that,  

Present value = (9% × $1,000) ÷ (8.75%) = $1,028.57

Assuming figure Future value = $1,000

Rate of interest = 8.4%

PMT = $1,000 × 9% = $90

The formula is shown below:

= NPER(Rate;PMT;-PV;FV;type)

The present value come in negative

So, after solving this, the answer would be 6.33 years

With examples of amino acids, explain the type of isomerism that exists in amino acids.​
Maslowich

Answer:

All amino acids are stereoisomers with the exception of glycine (because it has no chiral centers) and the two types are enantiomers and diastereomers

Explanation:

Not sure how in depth you need but the most fundamental categories are:

Enantiomers: non superimposable images which means that they cannot be placed on top of one another and look perfectly identical and instead are structurally the same but flipped in the opposite direction. An example being D-alanine and L-alanine.

Diastereomers: The molecules are superimposable which means they have an identical structure that will look the same placed on top of one another however, the compounds attached to the structure are placed in different orders an example being, L-isoleucine and D-allo-isoleucine (compounds in same place but isoleucine has two hydrogens positioned forward while allo-iso have one positioned forward and one positioned in the back)

The next 11 questions are related to the titration of 40.00 mL of a 0.0900 M acetic acid solution with 0.0700 M KOH. Assume that
liberstina [14]

Answer:

2.9 is the initial pH of the analyte solution.

Explanation:

The dissociation constant of acetic acid as per theoretical value =  K_a

K_a=10^{-4.756}=1.8\times 10^{-5}

The initial concentration of acetic acid = c = 0.0900 M

HAc\rightleftharpoons Ac^-+H^+

initially

c       0    0

At equilibrium

(c-x)      x  x

The expression of dissociation constant :

K_a=\frac{[Ac^-][H^+]}{[HAc]}

1.8\times 10^{-5}=\frac{x\times x}{(c-x)}

1.8\times 10^{-5}=\frac{x\times x}{(0.0900-x)}

Solving for x:

x = 0.001264 M

[H^+]=0.001264 M

The pH of the solution :

pH=-\log[0.001264]=2.898\approx 2.9

2.9 is the initial pH of the analyte solution.
