Consider the following statements: I) Real gases act more like ideal gases as the temperature increases. II) When n and T are constant, a decrease in P results in a decrease in V . III) At 1 atm and 273 K, every molecule in a sample of a gas has the same speed. IV) At constant T, CO2 molecules at 1 atm and H2 molecules at 5 atm have the same average kinetic energy. Which of these statements is true

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.
