Calculate the standard entropy change for the following reaction at 25 ã‚â°c. sã‚â° values can be found here. mg(oh)2 + 2hcl

Given reaction:

Mg(OH)2(s) + 2HCl(g) → MgCl2(s) + 2H2O(g)

Formula:

ΔS°rxn = ∑nS°(products) - ∑nS°(reactants)

           = [S°(MgCl2) + 2S°(H2O)] -[S°(Mg(OH)2 + 2S°(HCl)]

           = [89.3+2(188.7)] - [63.22+2(186.80] = 29.88 J/K

Thus, the standard entropy change for the reaction is around 30 J/K

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,

the objects have the same charge is correct.
