280 mL of an HCl solution with pH of 3.10 is added to 200 mL of an HNO3 solution. The resulting pH is 1.4. What was the pH of the original HNO3 solution.
Given that the delta H of vaporization = 35.00 kj/mol and delta H of sublimation= 40.00 kj/mol, calculate the triple point of this material. this compound melts at 170.0 k to 270.0 k temperature.
Explain how mass effects act to lower the carbonyl frequency, as well as how inductive and hyperconjugation effects act to raise the carbonyl
Explain why chemistry is such an important part of the study of Anatomy and Physiology. Please be sure to include specific examples of important chemical reactions as evidence of chemistry's importance to homeostasis.
