Question 12 (5 points) The reaction HCI(1) + H20 (1) ► H30 (aq) + Claq) can be abbreviated as HCI - H+ + Cl".
How is this apparently important omission justified?
A) It's generally understood that H2O+ is a hypothetical intermediary.
B)
It's understood that H+ doesn't exist on its own in water, and H30 faq)+ Cl(aq)
are both aqueous.
C) It isn't justified, and the abbreviation is an error.
D) Because water isn't important to the reaction

Calculate the molar mass of aluminum oxide (al2o3). express your answer to four significant figures.

0.09 moles of sodium sulfate in 12 ml of solution

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.
