A metal salt with the formula MSO4 crystallizes from water to form a solid with the composition MSO4⋅5H2O. At 298 K, the equilibrium vapor pressure of water above this solid is 15.7 Torr.

MSO4⋅5H2O(s)↽−−⇀MSO4(s)+5H2O(g)
What is the value of ΔG for the reaction when the vapor pressure of water is 15.7 Torr?

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
