    A hot metal at 125 oC was dropped into 75.0 g of water kept at a room temperature of 20.6 oC in a calorimeter. Within a couple of minutes, water’s temperature increased to 26.8 oC? (a) How much heat energy was absorbed by water? [‘c’ for water is 4.184 J/goC] (b) How much heat energy was released by the metal? (c) What information is needed to calculate the specific heat capacity of the metal?

    A 189 mL solution of a dilute acid is added to 193 mL of a base solution in a coffee-cup calorimeter. The temperature of the solution increases from 22.31 oC to 25.32 oC. Assuming the mixture has the same specific heat (4.184J/goC) and density (1.00 g/cm3) as water, calculate the heat (in J) transferred to the surroundings, qsurr.

    72 mL solution of a dilute AgNO3 solution is added to 66 mL of a base solution in a coffee-cup calorimeter. As AgOH (s) precipitates, the temperature of the solution increases from 23.45 oC to 25.39 oC. Assuming the mixture has the same specific heat (4.184J/goC) and density (1.00 g/cm3 or 1.00 g/mL) as water, calculate the heat (in J) transferred to the surroundings, qsurr.

    In a constant‑pressure calorimeter, 75.0 mL of 0.770 M H2SO4 was added to 75.0 mL of 0.450 M NaOH. The reaction caused the temperature of the solution to rise from 22.31 ∘C to 25.38 ∘C. If the solution has the same density and specific heat as water (1.00 g/mL and 4.184 J/(g⋅°C), respectively), what is ΔH for this reaction (per mole of H2O produced)? Assume that the total volume is the sum of the individual volumes.

    When a solid dissolves in water, heat may be evolved or absorbed. The heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. In the laboratory a general chemistry student finds that when 2.99 g of FeBrz(s) are dissolved in 102.70 g of water, the temperature of the solution increases from 25.90 to 29.34 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.59 J/°C....

    3. In a dissolution experiment, 5.0 g of NH4NOs was dissolved in 50.0 mL of water in a calorimeter If the calculated for the reaction was 1.7 kJ, calculate the observed Ar for the experiment. (Ignore the heat capacity of the calorimeter, i.e., use Ceup, -0. Assume the specific heat capacity of the solution = 4.18 J/g。C and the density of the water-1.0 g/mL)

    Part A A calorimeter contains 34.0 mL of water at 12.5 ∘C . When 1.50 g of X (a substance with a molar mass of 75.0 g/mol ) is added, it dissolves via the reaction X(s)+H2O(l)→X(aq) and the temperature of the solution increases to 25.5 ∘C . Calculate the enthalpy change, ΔH, for this reaction per mole of X. Assume that the specific heat of the resulting solution is equal to that of water [4.18 J/(g⋅∘C)], that density of water...
