F. Acid Equilibrium Calculations: 1. Calculation of equilibrium concentrations from Ka
Calculate the pH of a 1.0 M Acetic acid solution, using approximations. Ka = 1.8 x 10^-5
HC2H3O2 + H2O ⇆ H3O(+) + C2H3O2(-)

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Place the elements below in order of decreasing ionization energy. aluminum(al) chlorine(cl) magnesium (mg) sulfur(s)

How many protons, electrons, and neutrons are in each of the following isotopes? a. zirconium-90 b. palladium-108 c. bromine-81 d. antimony-123
