Asoil solution contained 12 ppm ca+2, 3 ppm mg+2, and 4 ppm k+[assume 10 g soil (ph 5) was extracted with 1 l bacl2solution]. estimate the cec. if the measured cec was 14 meq/100g soil, explain why there might be a difference in the measured and estimated cec?

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
