Use Table 1 to predict whether each of the follow- ing compounds is considered soluble or insoluble:
a. KCI
b. NaNO3
c. Aga
d. BaSO4
e. Caz(PO4)2
f. Pb(ClO3)2
g. (NH),s
h. PbCl2 (in cold water)
i. Fes
j. Al(SO4)3

c is the answer because when something is left after something evaporates that shows the chemical change.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

wher is the rest of the question
