Will mark brainliest! For the balanced equation shown below, what would be the limiting reagent if 141.0 grams of C8H18 were reacted with 512.9 grams of O2 How much of the excess reagent remains? What is the percent yield if the actual amount of CO2 produced is 371.4 grams?
2 C8H18 + 25 O2 => 16 CO2 + 18 H2O

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

you didnt put any of the following

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

the answers are

c and c
