In lab, a dialysis bag was filled with a 10% sucrose solution and placed in an unlabeled beaker filled with clear liquid. The dialysis bag was made of a semipermeable membrane that allowed the free passage of water, but was not permeable to sucrose. After two hours, the bag in the beaker decreased in size, lost volume, and became flaccid. Therefore, at the beginning of the experiment, the solution in the bag was compared to the solution in the beaker. g

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

o conteúdo de calor de um sistema é igual à entalpia apenas para um sistema que é constante

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

it is stable as it is in group 0 which have full outer shells of electrons
