Find the percent ionization of a 0.175 M CH3CH2CO2H solution. The Ka for CH3CH2CO2His 1.3 x 10^-5. I am getting [H+] =Sqr (.175)(1.3*10^-5)

Then taking [H+]/ [acid] initial

What am I doing wrong here?

When the following equation is balanced using the smallest possible integers, what is the coefficent of oxygen gas? c7h16o(g) + o2(g) → co2(g) + h2o(g) -1 -5 -8 -16 -21

Which statement is true about the part of the electromagnetic spectrum that human eyes can detect? it contains only the colors of the rainbow and television waves. o it is divided into seven ranges of wavelengths. it contains ultraviolet, visible, and infrared light. it is divided into nine ranges of wavelengths.

Acompound contains c, h, and o atoms. when 1.130 g of the compound is burned in oxygen, 1.064 g co2 and 0.3631 g h2o are produced. what is the empirical formula of this compound?
