HNO3 Has a 3 next to the O. this means that there are 3 oxygen atoms.
It could have pros because it may be a better technique, and helps you get more of what you want, but it could also have cons, because it could give back less than what you got with the other technique. This is like if you have a job filing paperwork, and you have a good technique or tool to help you along quickly, but you decide to try something new, and end up being able to get things done faster. However, you might decide to change your techniques again, and you may find that it gets things done much slower. Hope this helps.
