Question 3(multiple choice worth 2 points) when 3.5 mol al react with 12.5 mol hcl, what is the limiting reactant and how many moles of h2 can be formed? 2al + 6hcl yields 2alcl3 + 3h2 al is the limiting reactant, and 3.5 mol h2 can be formed hcl is the limiting reactant, and 3.2 mol h2 can be formed al is the limiting reactant, and 5.3 mol h2 can be formed hcl is the limiting reactant, and 6.3 mol h2 can be formed

Which type of bonding involves the complete transfer of a valence electron from a less electrogrative atom to a more electronegative one

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.
