Which of the following is equivalent to the bond enthalpy of the carbon-oxygen bond in carbon monoxide?
A. CO(g)=C(s) + O(g)
B. CO(g)=C(g) + O(g)
C. CO(g)=C(s) + 1/2O2(g)
D. CO(g)=C(g) + 1/202(g)

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.
