A mixture of 4 gases A, B, C, and D have a total pressure of 825.3 mmHg. If the partial
pressure of gas B is 452.2 mmHg, and the partial pressure of gas C is 210.3 mmHg, and the partial pressure of gas D is 98.2 mmHg. If you have 2.35 moles of gas A How many moles of gas B are present?

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.
