The reaction below shows the reaction of magnesium reacting with excess oxygen gas to produce magnesium oxide. Assume that 5.63 g of Mg reacts with excess oxygen to produce 8.38 g of Mgo.
2Mg + 0, → 2MgO
What is the approximate percent yield for this reaction?

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.

the answer is 75.0%.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
