It takes 2.16 J of heat to raise the temperature of Object A by 1 °C, and 4.64 J to raise the temperature of Object B by 1 °C. Suppose A and B are brought into contact. A is initially hotter. A is seen to cool down by 6.9 °C. How would you calculate the rise in temperature of B? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols. change in temperature of B = 0 Continue OO X 9 0.0 3 wevee muuiầw Hill LLC. All Rights Reserved.

10. Ethanol OH weighing 3.56 g is burned in a calorimeter. The temperature rises from 15.C to C. The temperature rises from 15.1 If to 28. heat of the bomb plus water is 8.224C. Find the Δ in kJ/mol. (provide the given and required to find in the problem) (Kindly provide a CLEAR and COMPLETE solution) (Answer should be typewritten)
You are performing an experiment where you place 9.2113 g of Al metal at 205.02 C into a coffee cup calorimeter that contains 98.4 g of water at 25.05 C. The final temperature of the water in the coffee cup is 28.89 C.Calculate the heat (q), in J, gained by the water using the equation, , given cwater= 4.184 J/g°CDo not include units. If you need to express your answer as an exponential number, use this template: 1445 should be typed as 1.445e+003
3. During the experiment, when calculating AH using the formula AH=C x AT, can we calculate the AH without measuring the amount of water that we put inside the calorimeter? Explain why or why not. (max of 5 sentences) 4. You accidentally forgot to measure the mass of the octane that you transferred in the crucible. You already started the calorimeter and it is too late to stop the equipment. Is it still possible to calculate the energy (in Joules) of octane? Explain.(max of 2 sentences)

1. Melted methane was ignited and used to heat water in a thin metal container. After a short period of time, the methane was extinguished and final measurements were made. = 7.52 g = 7.20 g Mass of methane before burning Mass of methane after burning Mass of water in container Initial temperature of water Final temperature of water = 140.0 g = 10.0°C = 32.0°C a) Using this data, calculate the heat of combustion of methane in kJ/mol. Assume that all the heat from the methane was absorbed by the water b) Write the thermochemical equation for the complete combustion of methane.
E Reading list [References) Use the References to access important values if needed for this question. In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. A student heats 63.30 grams of nickel to 99.15 °C and then drops it into a cup containing 76.81 grams of water at 23.29 °C. She measures the final temperature to be 29.57 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.51 J/°C. Assuming that no heat is lost to the surroundings calculate the specific heat of nickel. Specific Heat (Ni) J/g°C. Submit Answer Try Another Version 1 item attempt remaining
