What information does the complete ionic equation give?
A. It shows what compounds will react to form a precipitate.
B. It shows what compounds dissolved to form the ions.
C. It shows only the ions that are involved in the reaction.
D. It shows how the compounds actually exist in solution.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

Hello.the answer is  hydrosphere, geosphere, and biosphere  have a nice day

Molarity is moles of solute over liters of solution. idk if that is what you are talking about, but you can convert moles of solute to grams of solute using dimensional analyzes by using molar mass found on the periodic table.
