0.700 moles of an unknown solid is placed into water to make 150.0 mL of solution. The solution's temperature decreases by 8.41°C. Calculate ∆H, in kJ/mol, for the dissolution of the unknown solid. (The specific heat of the solution is 4.184 J/g･°C and the density of the solution is 1.02 g/mL).

the answer is learned

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

un recipient conține 6,4 moli de gaz. gazul hidrogen reprezintă 25% din totalul kilometrilor din container. în cazul în care presiunea totală este de 1.24 atm ceea ce este
