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.

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
A chemist carefully measures the amount of heat needed to raise the temperature of a 399.0 g sample of a pure substance from 4.1 °C to 19.7°C. The experiment shows that 865. J of heat are needed. What can the chemist report for the specific heat capacity of the substance? Round your answer to 3 significant digits. -1 -1 J.g •K x10 Submit Assignme Continue 2022 McGraw Hill LLC.

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.
