Answer:
Oxidation occurs simultaneously with reduction.
Because they get new pieces of information from experiments
The molar mass of Na₂SO₄ -
2 x Na - 2 x23 = 46
1 x S - 1 x 32 = 32
4 x O - 4 x 16 = 64
total = 46 + 32 + 64 = 142 g/mol
the molarity of solution - 2.0 M
in 1 L of solution , 2.0 moles
Therefore in 2.5 L - 2 mol/L x 2.5 L = 5 mol
then the mass of Na₂SO₄ required = 142 g/mol x 5 mol = 710 g
It was a spring morning of April 16, 1947, was a morning that many citizens of Texas City thought was the end of the world. The French Liberty ship, SS Grandcamp, bearing a cargo of ammonium nitrate fertilizer (over 2300 tons) destined for war-torn Europe, caught fire in the Texas City harbor. The bright ... A little after 9.00 a.m., the Texas City Disaster (as it is popularly known) occurred as the ship Grandcamp exploded.
