A 6.5g mass of ice with a temperature of 0 degree C is dropped Into Lake Erie, which is at a temperature of 15 degree C. What will be the final temperature, in Celsius, of the lake plus the ice? (You don't need to enter units. Just the numerical part of the answer.) If the latent heat of fusion of ice is 334kJ/kg and the specific heat of water is 4.18kJ kg-1 K-1 how much heat, in Joules, must 8.6g...

QUESTION 8 How does the internal energy of the ice and water mixture change if the temperature does not rise while the ice is melting? It decreases, because you need to use energy to make a freezer run, but ice melts spontaneously. No enough information to determine. It increases, because it takes more energy for water molecules to be disordered than to be ordered. It remains the same, because both are at the same temperature. QUESTION 9 Suppose you start...

QUESTION 0.5 pointsSave Answer What is the standard cell voltage in volts for a voltaic cell comprising Al as one electrode and inert Pt as the other electrode? Oxygen gas is bubbled onto the Pt electrode in acidic solutions. Hint: cathodic reaction does not involve Pt, it is oxygen reduction reaction, so find t in the table of standard reduction potentials for acidic solutions. a 2.89 C c C 3.8 d-3.8 e-4.0 Се.

A well-insulated, 64 fluid-ounce container is used for drinking water. Unfortunately, the water from the drinking fountain is about 75°F, a little too warm for average taste. To solve this problem, ice is added before filling it completely with water (volume of water and ice equals 64 fluid ounces). Calculate the precise amount of ice needed to cool the water to the coolest temperature that still provides optimal hydration (50°F) by the time all the ice melts and the temperature...
