For the reaction: Agl(s) + V2Br2(g) AgBr(s) + /12 ()
AH° = -54.0 kJ
And:
AH® for AgBr(s) = -100.4 kJ/mol
AH° for Br2(g) = +30.9 kJ/mol
Therefore value of AH for Agl(s) must be:
+61.8 kJ/mol.
-61.8 kJ/mol.
O-123.5 kJ/mol.
+77.3 kJ/mol.
O-77.3 kJ/mol.

Noble gases is far right

They can measure  the amount of energy gained or lost

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o
