My chemistry teacher asked that question... So I don't know...

Homework Statement Why do bases lose all of their hydroxides at once?Homework Equations N/A The Attempt at a Solution Polyprotic acids lose their hydrogen atoms in a step-wise fashion, but bases with multiple hydroxides do not do this. I'm not quiet sure why this occurs, but I think that...

Wow, I feel stupid for doing that. Finally got it now. Thank you all!

Homework Statement A curve is traced by a point P(x,y) which moves such that its distance from the point A(-1,1) is three times its distance from the point B(2,-1). Determine the equation of the curve. Homework Equations None The Attempt at a Solution Distance from Point A to...

Homework Statement Evaluate using the Squeeze Theorem. \lim_{x\rightarrow0} (2^{x} - 1) cos\frac{1}{x} Homework Equations The Attempt at a Solution -1 ≤ cos\frac{1}{x} ≤ 1 \\ 1 - 2^{x} ≤ (2^{x} -1)cos\frac{1}{x} ≤ 2^{x} - 1 \\ 0 ≤ (2^{x} -1)cos\frac{1}{x} ≤ 0 \\ ∴ \lim_{x\rightarrow0}...
