Ranking of the atom from highest to lowest is as follows:
Highest
Arrow = from outer edge to center
2nd Highest
Arrow = second closest ring to the outer edge to center
3rd Highest
Arrow = middle circle to center
Lowest
Arrow = outer edge to middle circle
The rate at which radioactive decay occurs & how much radioactive decay has occurred
THe balanced chemical reaction would be:
Na2CO3 + H2SO4 = Na2SO4 + H2O + CO2
We first convert the mass of sulfuric acid solution to moles by the molar mass. Then, we relate H2SO4 with Na2CO3 from the reaction. We do as follows:
<span>6.05×10^3 kg H2SO4 ( 1 kmol / 98.08 kg) ( 1 kmol Na2CO3 / 1 kmol H2SO4 ) ( 105.99 kg / kmol ) = 6537.92 kg Na2CO3 needed</span>
The main atomic partilces are electrons, protons and neutrons.
Electrons are around the nuclei and have negative charge.
Protons and neutrons are in the nulei of the atoms. Protons are positive and their charge balance the charge of the electrons, so the atom is neutral.
Neutrons have no charge.
So, the answer is:
the charge of electrons is negative, the charge of the protons is positive and the neutrons have no charge.
Potassium carbonate reacts with barium chloride to precipitate insoluble barium salts that is barium carbonate, when the solutions are mixed together you'll see white precipitate that is barium carbonate and potassium is dissolve in the solution to form potassium chloride.
