In a constant-pressure calorimeter, 50.0 mL of 0.340 M Ba(OH), was added to 50.0 mL of 0.680 M HCI. The reaction caused the temperature of the solution to rise from 22.91 °C to 27.54 °C. If the solution has the same density and specific heat as water (1.00 g/mL and 4.184J/g • °C,) respectively), what is AH for this reaction (per mole H,O produced)? Assume that the total volume is the sum of the individual volumes.
ped in a graduated cylinder with 42.1 mL of water in it. The water level after the nugget was placed in the water is 53.6 mL. Based on this, calculate the density of the gold nugget. If the accepted value for the density of gold is 19.3 g/mL, find the percent error.
In a constant pressure calorimeter 50.0 mL of 0.310 M Ba(OH)2 was added to 50.0 mL of 0.620 M HCl. the reactions caused the temperature of the solution to rise from 23.77 c to 27.99 c if the solution has the same density and same specific heat as water (1.00 g/mL and 4.184 j/g c ) what is triangle H for this reaction (per mole of H2O produced) assume that the total volume is the sum of the individual volumes
In a constant-pressure calorimeter, 50.0 mL of 0.350 M Ba(OH)2 was added to 50.0 mL of 0.700 M HCl. The reaction caused the temperature of the solution to rise from 24.49 C to 29.26 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 ?H for this reaction (per mole H2O produced)? Assume and the total volume is the sum of the individual volumes. ?H= _______ kJ/mol H2O
a powder has a mass of 40.0 g. when the powder is added to 30.0 ml of water the total volume is 45.0 ml. what is the density of the powder?
