2. Calculate the mass of 10 mL of 5 mol/dm of acetone and the associated molality

10. according to the law of conservation of mass, how does the mass of the products in a chemical reaction compare to the mass of the reactants?

The enthalpy of formation of water is -285.8 kj/mol. what can be inferred from this statement?

Click the button that shows the correct relationship of the electron affinities of the elements sodium and phosphorus. sodium’s electron affinity value is more negative than the electron affinity value of phosphorus. phosphorus’ electron affinity value is more negative than the electron affinity value of sodium. this information cannot be determined using the periodic table. answer is b on e2020.
