Question
Chapter 3, Problem 3.93P
Interpretation Introduction
Interpretation:
The role of sodium iodide commonly present in the table salt available at grocery stores should be determined.
Concept Introduction:
Iodine is one of the important mineral required by our body. It is required by our body for making of a hormone known as thyroid hormones secreted by thyroid gland for
In case of deficiency of iodine the thyroid hormone is not made in sufficient amount leading to many problems in our body. One of the visible signs of iodine deficiency is enlargement of thyroid gland known as goiter.

False
10.00 g of Compound X with molecular formula C₂Hg are burned in a constant-pressure calorimeter containing 40.00 kg of water at 25 °C. The temperature of
the water is observed to rise by 2.604 °C. (You may assume all the heat released by the reaction is absorbed by the water, and none by the calorimeter itself.)
Calculate the standard heat of formation of Compound X at 25 °C.
Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

During the lecture, we calculated the Debye length at physiological salt concentrations and temperature, i.e. at an ionic strength of 150 mM (i.e. 0.150 mol/l) and a temperature of T=310 K. We predicted that electrostatic interactions are effectively screened beyond distances of 8.1 Å in solutions with a physiological salt concentration.
What is the Debye length in a sample of distilled water with an ionic strength of 10.0 µM (i.e. 1.00 * 10-5 mol/l)? Assume room temperature, i.e. T= 298 K, and provide your answer as a numerical expression with 3 significant figures in Å (1 Å = 10-10 m).
