When a 1 M solution of glucose 6-phosphate is incubated with a catalytic amount of phosphoglucomutase, the sugar isomerizes to glucose 1-phosphate. At equilibrium, the concentrations of the reaction components are 960 mM glucose 6-phosphate and 45 mM glucose 1-phosphate. Calculate the equilibrium constant and standard free energy change for this reaction under standard state conditions.

The solid xy decomposes into gaseous x and y: xy(s) m x(g) + y(g) kp = 4.1 (at 0 °c) if the reaction is carried out in a 22.4 l container, which initial amounts of x and y will result in the formation of solid xy?

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.

An atom that gains or loses one or more electrons is called a(n)
