17. A pure compound melts at 48-49 degrees Celsius. If a trace amount of an impure compound, whose melting point is 80-82 degrees Celsius, is mixed in with the first compound, what happens to the melting point of the pure compound? A. The second compound would lower the melting point of the first one B. It is impossible to determine without knowing the identity of the two compounds. C. The second compound would raise the melting point of the first...

A 1000g sample of solid mercury at its melting point of -39.0C(Celsius) is placed in a 220g aluminum calorimeter with 430g of water at temperature of 12.8C. The final equilibrium temperature is 5.1C. From this determine the latent heat of fusion for mercury. Specific heats Mercury 0.138J/g/K aluminum 0.900J/g/K Water 4.186J/g/K
Q1) Plot a schematic of density vs temperature for water around it’s melting point between -15 and 15 degrees Celsius, from observing the simulation. Do the same for Oxygen around it’s melting temperature between -200 and -230 degrees Celsius (Oxygen melts at -218 C). Explain briefly how the difference between oxygen and water makes water particularly uniq
The boiling point of liquid nitrogen is 77.4 K at atmospheric pressure. (a) What is this temperature on the Celsius scale? °C (b) What is this temperature on the Fahrenheit scale? °F
A. The normal melting point of naphthalene is 80.0 °C. At 85.8 Celsius, the liquid has a vapor pressure of 10.0 Torr which increases to 40.0 Torr at 119.3°c. Use this information to calculate the heat of vaporization, the normal boiling point, and the entropy of vaporiza of naphthalene. How similar is your calculated entropy change to the prediction of Trouton's rule? B. Assume that the triple point temperature of naphthalene is also 80.0 Celsius and that the sublimation pressure...

Simple-RegressionTech: Problem 1 Previous Problem Problem List Next Problem (1 point) Measuring Temperature. The two most commonly used scales for measuring temperature are the Fahrenheit and Celsius scales. If you let y denote the Fahrenheit temperature and x denote Celsius temperature, you can express the relationship between those two scales with the linear equation y # 32 + 1.8x. a. Determine the y-intercept bo and the slope b .Note that a and b of the lecture notes are b-0 and...
