If the coefficients in a balanced chemical equation can represent mole ratios, why then can't we have coefficients like 1.2? A) coefficients also represent particles and particles like atoms, ions, and molecules MUST be whole numbers.

B) coefficients represent mole quantities and mole quantities MUST be whole numbers.

C) coefficients can be whole numbers OR fractions since one can have a fraction of a molecule just as one can have a fraction of a mole.

This chart lists four kinds of polymers and their sources. what can be known about all four polymers, despite their differences? they come from living things. they share ionic carbon bonds. they are at least 100 monomers long. they are made of repeating subunits.

How could a student test the effect of removing heat from a gas that is stored in a sealed container? what must occur in order for matter to change states?

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.
