[zn(oh)4]2− is a soluble species in water at 298 k, while zn(oh)2 is not. what is the minimum concentration of oh−(aq) required to dissolve 0.015 mol of zn(oh)2 in a liter of solution at this temperature? ksp for zn(oh)2 = 3.0 x 10−16 and kf for [zn(oh)4]2− = 4.6 x 1017

Explain why scientists use shared characteristics to make cladograms.

Freezing 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.
