Man I don't trust what I've learnt Just multiply the concentration to the amount of hydronium ions that are produced. However, aren't most diprotic and triprotic acids in a state of equilibrium? The pH will be greater than what you do from my working

Ok...then it must be because it's unfamiliar since some of them are conjugate bases themselves

Are there several trick questions there? It looks like it for some reason

yea C. H2SO4 is strong, the HS04 is weak, but it still gives off more hydronium ions Though I think citric, depending on it's position of equilibrium could over take h2so4

This sarcasm or what? I've never learnt that

The changing states of CO2 releases/absorbs heat beaten

Exactly what I wanted, though a few parts I don't get but it doesn't matter I was about to use numbers, but chose value because the probability is 0, as nothing is valueless :p Oh crap, I said "the value 0"

Integration focuses on areas and volumes. It involves finding the primitives-anti derivatives. It's not the process of finding the primitive, despite what everyone thinks

Don't get your question. Seems like you can prove it graphically (from what I understood from question)

What's the probability of me picking the value 0 out of all possible values that exist?

confusing If you were willing to learn you would've tolerated this font and not latex

You haven't specified whether or not your question is answered. Take your first equation a(r^n - 1)/ [r-1] = -a(r^n -1)/ -[r-1] = a(1-r^n)/[1-r] OMG, what? They're the same thing! No wonder it works whenever I use the "incorrect formula"...

Doesn't follow the syllabus well. Too much content that is irrelevant

No. It does however have everything in the syllabus

Mistakes in these questions are quite frustrating I know

nice work dude, they're exactly the same thing. Try multiplying one of the formulas with -1/-1. What do you get OMG?

This took 35 minutes to type up, hence this is why I will never ever post a full solution again

I got the solution...I remember a thread made here aggeess ago about this question. I don't think anyone got the answer. At that time I didn't learn projectile motion but anyway I'll actually post the solution. The birds path is the boldest line. Since the bird flys horizontally, the rock...

You basically said what he said...I think
