Remember entropy values are in units of joules.
must convert to kJ in some problems IF any errors pop up and do sometimes, please let me know!!

The specific heat of copper metal is 0.385 J/g ·°C. How many joules of heat are necessary to raise the temperature of a 1.40 g block of copper from 30.6°C to 89.8°C?
(b) Calculate the amount of heat transferred when 55.0 g of CH3OH(g), molar mass = 32.04g/mol, are decomposed by this reaction at constant pressure.
(b) LiCl(s) is formed from Li(s) and Cl2(g).
(c) Zinc metal dissolves in hydrochloric acid, forming ZnCl2(aq) and H2(g).
(d) Silver bromide precipitates upon mixing AgNO3 and KBr(aq).
(b) Does the reaction lead to an increase or decrease in the disorder of the system?
(c)[Answer sig. to 0.1’s place] Calculate G° for the reaction at 298 K.
(b) 6 Cl2(g) + 2 Fe2O3(s) 4 FeCl3(s) + 3 O2(g)
(c) 2 CH3OH(l) + 3 O2(g) 2 CO2(g) + 4 H2O(l)
