iPad 6:32 PM * 33% Exit A 50.0 g silver spoon at 20.0°C is placed in a cup of coffee at 90.0°C. How much heat (in kcal) does the spoon absorb from the coffee to reach a temperature of 89.0°C? (Assume Csilver-0.056 kcal/kgC.) Question 13 1 pts A 200.0 g china serving bowl is warmed 65.0°C when it absorbs 2.6 kcal of heat from a serving of hot food. What is the specific heat of the china dish? Question 14...
A 33.0 g silver spoon at 18.2°C is placed in a cup of coffee at 94.1°C. A short time later, the spoon is at 91.1°C. If, during this same time, the temperature of the coffee has fallen by 0.6°C,what is the mass of the coffee? (csilver = 0.056 cal/g°C and assume ccoffee = 1.0 cal/g°C)
how much will the temperature of a cup (180) of coffee at 95 c be reduced when a 45g silver spoon (specific heat 0.24 j/g c ) at 25 c is placed in the coffee and two are allowed to reach the same temperature? Assume that the coffee has the same density and specific heat as water.
A student performs the following experiment : a coffee cup calorimeter contains 50.0g of water at 20.0 degrees Celsius. A student pours an unknown amount of warm water at 55.0 degrees celcius into this cup. The final temperature of the combined water is 34.6 degrees celsius. a. calculate the amount of heat absorbed by the cool water including the sign of q b. calculate the amount of heat released by the WARM water, including the sign of q c. calculate...
How much heat does 29.0 of water absorb, if its temperature increases from 20.0 C to 46.0 C ? The specific heat capacity of water is 4.18 J/(g.C)
if the silver spoon placed in the coffee in exercise 6 (THE QUESTION BEFORE THIS) causes it to cool 0.75 C, what us the mass of the coffee?Assume C coffee = 1.0 cal/gCplease show work
A spoon was silver-plated electrolytically in a AgNO3 solution. If 0.750 g of Ag was deposited on the spoon at a constant current of 20.0 mA, how long (in hours) did the electrolysis take? (1 mA = 1x10–3 A) 11.9 hr 9.32 hr 5.92 hr 8.76 hr 10.1 hr
A 4.15 g sample of silver is heated from an initial temperature of 20.0 °C to a final temperature of 29.1 °C, which required 8.7 J of heat. What is the specific heat capacity of silver? 329 J K-1 g1 0.07 J K-1 g1 3.97 J K-1 g1 0.23 J K1 g1 0.10 J K1 g1
An aluminum cup of unknown mass contains 200 g of water and a 100 g copper stirrer, all at 20 degrees Celsius. A 600 g sample of silver at an initial tempreature of 100 degrees Celsius is placed in the water. The stirrer is used to mix the water until the mixture reaches thermal equilibrium at 30 degrees Celsius. A. How much heat does the water absorb? B. How much heat does the copper stirrer absorb? C. How much heat...
