Answer:

The correct answer is option B) The mass number of the radioactive nuclide is 131

Explanation:

Hello!

Let's solve this!

Among the isotopes of Barium is 131 / 56Ba. This means that the mass number (total protons plus neutrons) is 131. The atomic number (number of protons) is 56.

Then, 131-56 = 75 that is the number of neutrons.

After the analysis we conclude that the correct answer is option B) The mass number of the radioactive nuclide is 131

Os etapas que devem sem compridas para obter separadamente os componentes (a as substâncias ) de uma mistura de água ,sal e arei
SashulF [63]

Answer:

The steps that must be long to obtain separately the components (to the substances) of a mixture of water, salt and sand, are respectively: A) filtration and siphoning B) decanting and siphoning C) simple filtration and distillation D) collection and decantation.

Simple filtration and Siphoning is the method. When an insoluble solid is present in a liquid. Filtration is the ideal method of separation,The sand is filtered by the filtered paper as water is allowed to pass through the filter paper into a beaker where the funnel which hold the filter paper emptied into.

Water molecules is Siphoned, pull by force of gravity through the sand, past  the filter paper to emerge as clean in the beaker below.
