If 1.029 g of copper(II) sulfate is allowed to react with 0.433 g of sodium carbonate, what will be the theoretical mass (in grams) of copper(II) carbonate precipitate formed? Round to the nearest thousandth of a gram.

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.

B. a graduated substance

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
