Enthalpy and entropy in solution question?

Could you please help me with this question? I don't really understand what entropy is and I've had little success looking in my book or notes.

    enthapy change is negative (heat is released)

    entropy change is positive (more disorder) as there are MORE molecules of gas created than reacted

    delta G = delta H - TdeltaS G = gibbs loose capability, that would desire to be unfavourable for a reaction to proceed in the forward course. H = enthalpy (warmth content fabric - can basically calculate the replace in enthalpy.. because of the fact there is not any absolute scale. replace in enthalpy is deltaH) T = temperature, which would be measured with a thermometer. might desire to be in Kelvin nevertheless S = entropy ( a level of entire illness in a equipment. this does have an absolute scale and subsequently may well be measured, yet oftentimes we use the replace in entropy besides... the completed entropy of the universe can tend in direction of a optimal, meaning whilst something will boost in entropy that's a themodynamically favoured technique)
