The values of Δ H ∘ , temperature and pressure for the stated reactions are given. The value of Δ S surr is to be calculated in each case. Concept introduction: Entropy is the measure of degree of disorder or randomness. Entropy of surrounding ( Δ S surr ) decreases for endothermic process whereas, it increases for exothermic process.

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.
need help not sure what am doing wrong step by step please answer is 971A
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).
