A coffee cup calorimeter contains 25.0 g water at 23.8 C. A 5.00 g sample of an unknown metal at an initial temperature of 78.3 C was dropped into the calorimeter. The final temperature of mixture was 46.3 C. Calculate the specific heat of the metal. The specific heat of water is (4.184)

The following thermochemical equation is for the reaction of carbon monoxide(g) with oxygen(g) to form carbon dioxide(g). 2CO(g) + O2(g)- →2CO2(g) AH=-566 kJ How many grams of CO(g) would have to react to produce 104 kJ of energy? grams

6.70 J heat is added to 5.71 g sample of unknown metal and temperature of metal increases by 0.798 degrees C. What is the specific heat of the unknown metal?

In an experiment, 26.5 g of metal was heated to 98.0°C and then quickly transferred to 150.0 g of water in a calorimeter. The initial temperature of the water was 22.5°C, and the final temperature after the addition of the metal was 32.5°C. Assume the calorimeter behaves ideally and does not absorb or release heat.

A 50.8 g sample of an unknown metal was heated to 700.0 ˚C then placed into 100.0 g of water (specific heat: 4.184) initially at 25.0 ˚C. The water and the unknown metal reach equilibrium when both are at 78.3 ˚C. What was the specific heat of the unknown metal?

What is the specific heat of a 45.51 g piece of an unknown metal that exhibits a 45.2 °C temperature change upon absorbing 1870 J of heat?

A chunk of gold (specific heat: 0.126) initially at 82.2 ˚C is placed in 75.5 g of water (specific heat: 184) initially at 22.0 ˚C. After a short time, both the water and the gold are at 41.0 ˚C. What was the mass of the gold?

A 146.3g piece of iron (specific heat = 0.449 J/g°C) is heated with a flame and dropped into a coffe cup calorimeter containing 450.0 g of water. the water (specific heat = 4.18 J/g°C) in the calorimeter increases from 20.3°C to 32.0°C. what was the initial temperature of iron?

n 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 63.03 grams of chromium to 98.03 °C and then drops it into a cup containing 79.71 grams of water at 23.19 °C. She measures the final temperature to be 28.85 °C.The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.57 J/°C.Assuming that no heat is lost to the surroundings calculate the specific heat of chromium.   Specific Heat (Cr) =  ____________J/g °C.

A 75g sample of a metal at temperature of 100℃ is placed in a calorimeter. The calorimeter contains 100g of water at a temperature of 34.4℃. The final temperature of the metal and the water in the calorimeter is 44.9℃. What is the specific heat of the metal? (cwater = 4.184J/g℃)
