Problem- What is the chemical equation for the above. Is there a reaction? If so, what are the balanced 1) molecular, 2) ionic, 3) net ionic equations? What are the states in the net ionic equation
Is imidazole an aromatic compound? Explain. Remember to account for non-bonding electrons on the nitrogen atoms. Which nitrogen atom is more likely to be protonated in an acid solution?
Which of the following pairs has about the same atomic radius?
A lot of trouble with this question, I think because it gives you the molarity of PCl5 but asks for atm at the end and I'm not really sure how to solve the question that way. I first found deltaG standard to be 2.75 kJ, then plugged that in to find t..
