You should clean up after every investigation because if you leave a mess, maybe another detective will come in and get lost because of the mess you left.
The mass of sodium sulfite that was used will be 1,890 grams.
<h3>Stoichiometric problems</h3>
First, the equation of the reaction:

The mole ratio of SO2 produced and sodium sulfite that reacted is 1:1.
Mole of 960 grams SO2 = 960/64 = 15 moles
Equivalent mole of sodium sulfite that reacted = 15 moles
Mass of 15 moles sodium sulfite = 15 x 126 = 1,890 grams

#SPJ1
No atoms are lost or made during the chemical reaction so the total mass of the products is equal to the total mass of the reactants. In an atom, protons and neutrons contribute to the mass and since the number of them doesn’t change, the mass doesn’t either.
Answer:
the answer is 18 atoms [your welcome]
Answer:
It would be the first one
Explanation:
According the solubility rules if SO4 is with Pb then it is insoluble.
