What is the pH of a 0.025 M aqueous solution of sodium propionate?
NaC3H5O2(aq) + H2O(l) <---> HC3H5O2(aq) + Na+(aq) + OH-(aq)
The Na+ is a spectator ion, so it can be eliminated from the equation to give:
C3H5O2-(aq) + H2O(l) <---> HC3H5O2 -(aq) + OH
A ball is thrown upward from the roof of a 25m building. The ball reaches a height of 45m above the ground after 2s and hits the ground 5s after being thrown. What is the equation for this function?
