One of the reasons that solid CuSO4 dissolves in water is: a instantaneous dipole-induced dipole forces (dispersion or London forces) between the Cu2 and the SO42- ions b the ion-dipole forces between the ions and the water molecules c the electrostatic force of attraction between the Cu2 and the SO42- ions d the hydrogen bonding between the water molecules e instantaneous dipole-induced dipole forces (dispersion or London forces) between the water molecules

How much energy is made when a pice of wood burns. how do you know

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .

Write and balance the chemical equation that represents the reaction of aqueous sulfuric acid with aqueous sodium hydroxide to form water and sodium sulfate. include phases.
