The diagram below shows dna molecules. what do the broken lines connected to hydrogen atoms represent in this diagram? the weakest intermolecular forces the weakest intramolecular forces the strongest intermolecular forces the strongest intramolecular forces

What is the subscript for oxygen in its molecular formula

At which temperature would a reaction with ah= -220 kj/mol and as=-0.05 kj/(mol-k) be spontaneous?

4al + 3o2 → 2al2o3 what does the "3" in front of o2 stand for? a) it indicates that there are 5 oxygen atoms after you add the coefficient and the subscript. b) it indicates that that there are are total of 6 oxygen atoms all bonded together as a single molecule. c) it indicates that there are 3 oxygen molecules chemically bonded to each other in the reaction. d) it indicates that there are 3 separate oxygen molecules in the reaction.
