7. La ecuación: NH, NCO (ac
(NH) CÓ
Es caracteristica para la obtención de urea a partir de cianato de amonio en solución acuosa.
La ecuación de velocidad es v = KINH NCOR, donde k = 0.025 L/molmin. Si se tiene una concen-
tración inicial de NH NCO de 0.325 mol/L, ¿qué tiempo se necesitará para que la concentración
disminuya a 0.220 mol/L?​

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

did anyone actually do this? like if anyone has submitted this i rly need .
