b) Ca(OH)2(s)

Answer 1

hey is there any other info given???

Answer 2

yeah it says to use appendix L. Hold on

Answer 3

ok

Answer 4

HCl:

\[DeltaH _{f}=-92.31\]
\[DeltaS=186.2\]

Answer 5

we need delta Q

Answer 6

DeltaGf=-95.09

Answer 7

is that what you need?

Answer 8

ok wait

Answer 9

see u know formula for Gibb's Free Energy???

\[\Delta G = \Delta H - T \Delta S\]
U hv G, H and T.
Find S

Answer 10

ok thanks. yeah i just had the formula wrong
