The reaction ( \text{Ca(OH)}_2(s) \rightleftharpoons \text{Ca}^{2+}(aq) + 2 \text{OH}^-(aq) ) with a change in enthalpy (( \Delta H )) of -16.71 kJ indicates that the dissolution of solid calcium hydroxide in water is an exothermic process. This means that heat is released when calcium hydroxide dissolves, resulting in a slight increase in the temperature of the solution. The negative value of ( \Delta H ) suggests that the products (dissolved ions) are more stable than the reactant (solid calcium hydroxide) in terms of energy.

Is a violin hand made in 1790 with the name Stradivarius worth anything?

First, all violins made before the 20th century are hand made, and most today still are.Antonius Stradivarius lived from 1644-1737. If you had one of the Cremona Violins made by Antonius it would be worth several hundred thousand dollars. Even copies are still worth several thousand dollars.His sons, Francesco Stradivarius (1671-1743) and Omobono Stradivarius (1679-1742), worked with him and continued the craft after his death, and they aren't worth quite as much, but are still highly sought after.What you probably have is a copy made by Ferdinandus Gagliano. He was alive during that time-frame and made violins branded with Stradivarius. I can't give you an exact price, but hopefully someone else can take this information and give you a more proper assessment. If I were in possession of it, I wouldn't sell it for less than $3,000 USD
