The starship enterprise uses the compound, B5H9 and oxygen gas as fuel. This is the balanced equation: 2B5H9 + 12O2 = 5B2O3 + 9H2O If one fuel tank holds 126 g of B5H9 and the other holds 192 g of Oxygen how much B2O3 will be produced? What is the limiting reagent? How much of the excess fuel will be left over? If 171.3 g of B2)3 is actually produced, what is the percent yield?

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.
