Quadratic equation and Radical function!
Please help with these two problems!
1) a) Find a radical function where f(4)=0 and f(16)=6
b) Find a radical function where f(4)=0 and f(2)=2
2) a) find a quadratic function where the vertex is (3,-1) and has a vertical intercept of (0,8)...
__________HA <------> H+ + A-
initial (mol) .1 ________ 0 ___ 0
change __ -x _______ +x ___ +x
final _____.1-x _______ x ___ x
Ka = 10^-8
find pH of .1 mol acid
since ka X 100 = 10^-6 < .1 can use initial concentration: .1-x = .1
Ka = [H+][A-]/[HA]...
