Reactions and Stoichiometry
What is the only letter of the alphabet that DOESN'T appear on the periodic table?
J (also accept Q, but it used to be there for Uuq)
What color is liquid oxygen?
Blue
A salt dissolves in water in a calorimeter and the forces formed are weaker than those broken. If the calorimeter does not insulate completely, how does the enthalpy change measured compare to the true enthalpy change for the dissolving? (give the sign of the enthalpy change and how the experimental value deviates from true)
The experimental enthalpy change is positive and smaller in magnitude than the true value
