nocyclic. compietely conjugated polyene to he aromat 3. Which of the follow ing would be a correct number ol p electrons for a planar. mo A, 3 B, 14 20 D, 24 Which of the follow ing is an alkylacetylene o O COOH C A. Solution 3. The answer for question no 3 is B as for a polyene to be aromatic, it must have 4n+2 pi electron. This is known as Huckel\'s rule for aromaticity. So, here 4*3+2 = 14. 4. The answer is C. acetylene denotes triplebondCH or alkyne and alkyl group may be methyl, propyl groups etc so answer C corrosponds to methylacetylene. 19. The answer is D. as we know that for a molecule to be aromatic, pi electrons should be conjugated. In A and B option, positive charge also plays a role in conjugation however, there is break in conjugation due to CH 2 group. 20. The answer is A. Although the conjugation is not complete, still among all, the molecule possess higher conjugation.than other molecules .

Neuron cells generate electrical signals by concentration gradients across membranes. Assuming a potassium ion concentration of 0.00350 M inside the cell, and a concentration of 0.135 M outside the cell, what is the electrical potential across the cell membrane? Body temperature is 315 K. The sign identifies the change in the electrical potential across the membrane and which way the ions flow. (answer in mV) Solution Let us consider Nernst equation: E = (RT/zF)ln([X] out /[X] in ) where, R = gas constant , 8.314J/Kmol T = Temperature, 315K z = Charge of the ion , for K+ it is +1 F = Faraday constant, 96485C/mol Therefore, E =((2.303Ã— 8.314(J/K mol) Ã—315K)/(+1Ã—96485C/mol))log(0.135M/0.0035M) = 0.0625VÃ—log(0.135/0.0035) E= 0.099V .

nest Rutherford was a prominent scientist who contributed significantly to the theory of atomic structure. Which of the following statements are true? Select all that apply. Rutherford devised the solar system model to describe the layout of the atom. Rutherford disproved the plum pudding model of the atom. Rutherford theorized that atoms contain a positively charged region called the nucleus. Rutherford devised the plum pudding model to describe the layout of an atom. Solution Correct one: c) Rutherford theorized that atoms contain a positively charged region called the nucleus. After completing the alpha-particle scattering experiment, he theorized the presence of nucleus. Due to which plum pudding model given by J.J. thomson got disapproved. .

Need some help!! Explain why all polynomial functions are continuous. Explain how to find an irrational zero. Describe the concept of continuity. Provide one example of a continuous function and one example of a discontinuous function. Why is it important to know synthetic division? What is another way to accomplish the same thing? Solution yes. all polynomials are continuous. reasons for discontinuity: 1. there is a denominator (which becomes 0 for some value of x) 2. there is a split in the definition of the function - this is for a piecewise function 3. there is a radical (even-indexed) for a polynomial, none of these cases occur.. . . thus there is no value of x where you expect a discontinuity. .

On January 1, 2014, Richards Inc. had cash and common stock of $62,150. At that date, the company had no other asset, liability, or equity balances. On January 2, 2014, it purchased for cash $20,810 of equity securities that it classified as available-for-sale. It received cash dividends of $4,700 during the year on these securities. In addition, it has an unrealized holding gain on these securities of $6,260 net of tax. Determine the following amounts for 2014: (a) net income; (b) comprehensive income; (c) other comprehensive income; and (d) accumulated other comprehensive income (end of 2014). Solution a. Net Income = $4,700 b. Comprehensive Income = $4,700 + $6,260 = $10,960 c. Other Comprehensive Income = $6,260 d. Accumulated Other Comprehensive Income = $6,260 .

On January 1, 2014, Jay Company had 10,000 shares of $1 par common stock outstanding, and 4,000 shares of $100 par value, 7% cumulative, nonconvertible preferred stock. On April 1, 2014, Jay Company had a 2-for-1 stock split. On July 1, 2014, Jay Company issued 5,000 additional shares of common stock. What is the weighted average shares outstanding to be used in basic earnings per share for 2014? A) 20,000 B) 22,500 C) 25,000 D) 27,000 Solution Weighted average shares outstanding to be used in basic earnings per share for 2014 = 10000*2*12/12 + 5000*6/12 Weighted average shares outstanding to be used in basic earnings per share for 2014 = 22500 Answer B) 22,500 .

On January 1, 2011, Phoenix Co. acquired 100 percent of the outstanding voting shares of Sedona Inc. for $600,000 cash. At January 1, 2011, Sedona\'s net assets had a total carrying amount of $420,000. Equipment (eight-year remaining life) was undervalued on Sedonass financial records by $80,000. Any remaining excess fair over book value was attributed to a customer list developed by Sedona (four-year remaining life), but not recorded on its books. Phoenix applies the equity method to account for its investment in Sedona. Each year since the acquisition, Sedona has paid a $20,000 dividend. Sedona recorded income of $70,000 in 2011 and $80,000 in 2012. Selected account balances from the two companies Solution Income from phoenix = Revevue - Expenditure = $148,000 Income from Sedona = $55,000 Net consolidated income = $148,000+$55,000 = $203,000 Answer B $203,000 .

On a circular track with 24 ?elds two players Blue and Yellow place their eight tokens in pairs so that blue an yellow pairs are separated as in Figure 1. Then they take turns to move one of their own tokens an arbitrary number of ?elds, in an arbitrary direction, but not onto or over an occupied ?eld. The player who can Solution two players can overthrow a adjacent player by teaming up and moving on the positions acquired by the adjacent player so that after the 1st step its position can be defensed so then it will have no other option to move in any direction. 2)blue can acquired the adjacent positions of the yellow players.aso in the next move yellow cannot move out of the boundary created by the blue. so the only option it will have is to move in ward.repeat such that it gets no more steps to go to. .
