Hello!
Antifreeze says it in the name. This means that it helps prevent freezing. The liquid that would freeze if you wouldnt use the antifreeze is water. This means that the antifreeze has to have a higher freezing point then water, because otherwise it would only freeze faster!
Hope this helped you!
The textbook Would most likely have more gravitational potential energy because it is heavier. Things that are heavier have a larger gravitational pull and are pulled to the earth faster
First its ... higher energy of reactants , higher energy of products & you do the same with the lower ones than you do transition state
P=18000000/6 zeros. not sure how to do rest
