MgCl2(s) + H2O(l) → MgO(s) + 2 HCl(g)
Using the standard enthalpies of formation given in the source below:
(−601.24 kJ) + (2 x −92.30 kJ) − (−641.8 kJ) − (−285.8 kJ) = +141.76 kJ
So:
MgCl2(s) + H2O(l) → MgO(s) + 2 HCl(g), ΔH = +141.76 kJ
B.
Delta G is negative and Delta S is positive.
It has 7.22 moles.... mole =mass/molar mass
molar mass of H2O=18
130/18=mole
False the output force and input force is low because the formula is output force divided by input force. Just a note you are not doing much input force into the screw because you hold the screwdriver
