6. Mercury (I) nitrate should have the formula HgNO3, but spectroscopic and freezing point depression studies indicate (and it is now accepted) that in fact the formula is Hg2(NO3)2 (because the mercury(1) ion is a diatomic ion Hg22). What value for i would you expect for a 1 m solution based on the formula HgNO3? What would be the / value for Hga(NO3)2? HONO: Hg2(NO3)2 7. Using salt as a de-icing substance can result in...
Without doing a calculation, choose the answer that best describes the pH of a 0.01 M solution of H2SO4. Note that -log(0.01) = 2 a. The pH is slightly greater than 2.0 b. The pH is slightly greater than 7.0. c. The pH is slightly less than 2.0. d. The pH is slightly less than 7.0. e. The pH is equal to 2.0.
Please choose the best answer possible. Thanks.

Choose the answer that best describes the relative acidity of hypobromous (HBrO) and hypoiodous (HIO) acids. Note: although by convention the H is written first, it is actually attached to the oxygen in each case. A. HBrO is more acidic than HIO because Br is more electronegative than I. B. HBrO is more acidic than HIO because I is more electronegative than Br. C. HIO is more acidic than HBrO because I is larger than Br. D. HIO is more...
Mercury(I) chloride consists of dimeric mercury(I) cations (with a formula of Hg22+) ionicly bonded to chloride ions forming an ionic lattice of Hg2Cl2(s). Elemental mercury reacts with chlorine dioxide gas to produce mercury(I) chloride and oxygen gas. (a) Write the balanced chemical equation for this reaction. (b) Calculate Delta Hrxn for this process. (c) Is chlorine dioxide gas likely to be diamagnetic or paramagnetic? Explain how you know. (d) Is the magnitude of the lattice energy of Hg2Cl2 more likely...
The first part of the question:
An alternate model for the reaction of mercury(I) and
thallium(III) is to have the first step of the mechanism come to a
rapid pre-equilibrium. What is the equilibrium constant for this
elementary step at 25.0 °C?
I got
but the answer is
. How is this so?
The second part of this question:
A concentration cell is set up such that the Hg2+ ion is at unit
activity in both compartments initially. To one...
1. From Figure 9-2 and the equations above choose which
plot best describes the impedance due to:
a. A Resistor
b. A Capacitor
PART 1: IMPEDANCE OF A CAPACITOR PREPARATION In an AC circuit capacitors and inductors have an effective resistance that restricts the flow of current, this is known as impedance. An equivalent to Ohm's law can be written where resistance R is replaced by the impedance Z: V = 12 (9-4) where V and I are either...
