A metal sample weighing 43.5 g and at a temperature of 100.0 °C was placed in 39.9 g of water in a calorimeter at 25.1 °C. At equilibrium, the temperature of the water and metal was 33.5 °C. Determine the specific heat capacity of the metal.
A metal sample weighing 43.5 g at a temperature of 100.0 °C was placed in 39.9 g of water in a calorimeter at 25.1°C. At equilibrium, the temperature of the water and metal was 33.5°C. What was ΔT for the water? (ΔT = Tfinal - Tinitial) What was ΔT for the metal? Using the specific heat of water (4.184 J/g°C), calculate how much heat flowed into the water. Calculate the specific heat of the metal.
Lead is a highly poisonous metal. The mass percentage of lead in the 250 g aqueous solution was found to be 1.2×10−6% by extracting the lead with an excess of iodide and weighing the resulting PbI2. How many micrograms (μg) of lead iodide were measured? Your answer should have two significant figures (round to the nearest tenth). 3 is not the answer
