<span>NaOH + HCl → NaCl + H2O
1 mol 1 mol
</span>2.75 × 10⁻⁴ mol 2.75 × 10⁻⁴ mol
M(H2O) = 2*1.0 +16.0 = 18.0 g/mol
2.75 × 10⁻⁴ mol H2O * 18.0 g H2O/1 mol H2O = 4.95*10⁻³ g H2O
Reorder 4Fe and 3O2.
3O2 + 4Fe
Sulfur has the coefficient of 2, and nothing else. This indicates Sulfur has 2 atoms.
<span>Oxygen on the other hand, has a subscript of 2, as well as the coefficient of 2. Multiplying those, and you see Oxygen has 4 atoms.
</span>
So your answer is 2
Also remember there is a 2 in front of S meaning there are 2 Sulfurs.
<span>If it was S02 it would be 1 Sulfur as there is no number in front of sulfer. </span>
<span>Remember the number in front of a element, represents how many atoms there are :)</span>
