Question- A voltaic cell is constructed that uses the following reaction and operates at 298 K. (Ered Ni+2 is -0.277) Zn(s) + Ni2+(aq) Zn2+(aq) + Ni(s) (a) What is the emf of this cell under standard conditions? Correct: Your answer is correct. V (b) What is the emf of this cell when [Ni2+] = 3.98 M and [Zn2+] = 0.184 M? V (c) What is the emf of the cell when [Ni2+] = 0.292 M and [Zn2+] = 0.808 M? V
Explain why the melting temperature of a double-helical DNA increases when the Na+ concentration increases.
If 5.20mL of 0.1000 M NaOH solution is needed to just neutralize excess acid after 20.00 mL of 0.1000 M HCl was added to 1.00 g of an antacid, how many moles of acid can the antacid counteract per gram?
Why would we obtain the same equation of state for linear molecules and non-linear molecules ( that is, taking rotations and vibrations into account
A solution is made by mixing 15.0 g of NaOH and 71.0 mL of .19 M HNO3. Calculate the concentration of Na+ ion remaining in solution.

How would I name the organic compound with a 5 carbon chain, one double bond between 3,4 carbons and 2 Br groups on the 2,4 carbons
An isolated chamber with rigid walls is divided into two equal compartments, one containing gas and the other evacuated. The partition between the compartments ruptures.
The protein in a 1.285-g sample of an oat cereal is determined by the Kjeldahl procedure for organic nitrogen. The sample is digested with H2SO4, the resulting solution made basic with NaOH
The moment of inertia for CH4 can be computed from the expression I=(8/3)mR2 where R is the CH bond length (109 pm). Compute the first three energy levels for this molecule if it rotates in 3D. Explain what is the degeneracy of its rotational stat..
