The specific heat of a certain type of metal is 0.128 J/(g. C). What is the final temperature if 305 J of heat is added to 49.7 g of this metal, initially at 20.0 °C? Tinal = °C

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

One beaker contains 244 g of water at 24 °C, and a second beaker contains 69.2 g of water at 95 °C. The water in the two beakers is mixed. What is the final water temperature? Final water temperature = °C.

Suppose 2.32 kJ of heat is added to 25.4 g of ethanol at 18.71 °C. The specific heat capacity of ethanolis 2.46 J/g °C. What is the final temperature of the ethanol?

A 18g sample of a material absorbed 898 calories, raising the temperature of the anitmony from 33 degrees C to its melting point (389 degrees C). Calculate the specific heat (cal/g degrees C) of this material.

Consider the combustion of liquid C₅H₈ in oxygen gas to produce carbon dioxide gas and water vapor. In an experiment, 0.1063 g of C₅H₈ is combusted to produce enough heat to raise the temperature of 150.0 g of water by 7.632 °C. How much heat, in J, was absorbed by the water assuming the specific heat of the water is 4.184 J/g･°C?
