Answer:
moles O₂ needed = 0.19 mole
Explanation:
4Fe(s) + 3O₂(g) => 2Fe₂O₃(s)
1.396g Fe(s) = 1.396g/56g/mol = 0.025 mole Fe(s)
0.025 mole Fe(s) reacts with 3/4(0.025 mole O₂(g) = 0.019 mole O₂(g)
That practice is over that day?
C. The valence electrons spend more time around the atom of Cl.
Explanation:
d.NaCl is a neutral salt, not an acid
