If you carry out the reaction between table salt (NaClNaCl) and copper(II) sulfate (CuSO4CuSO4 ) in 100.0 mL100.0 mL of water, the salt copper(II) sulfate will behave similarly to the salts given in the tab named Slightly Soluble Salts. Enter the formula for the precipitate (without the phase) that will be formed. If no precipitate is formed, simply type "noreaction" in the answer box.Express your answer as a chemical formula.

for copper the variation with temperature for heat capacity at constant pressure is Cp=22.46+(00.628) calculate the change of the molar enthalopy when temperature change from293 to 393

What mass of calcium chloride is needed to make 330.0 mL of 0.125 M solution?

Considering you do not focus on the electron configuration to determine the magnetic property of atom, instead, you are to determine it experimentally. How does a diamagnetic substance react to a magnetic field? How will a molecule react if it contains more unpaired electrons? *
