The answer would be a/ N2
The reaction will produce 71.5 g Fe
.
<em>Step 1</em>. Write the <em>balanced chemical equation
</em>
3Fe(NO_3)_2 + 2Al → 3Fe + 2Al(NO3)_3
<em>Step 2</em>. Calculate the <em>mass of Fe(NO3)_2
</em>
Mass = 305 g solution × [75.5g Fe(NO_3)_2/100 g solution]
= 230.3 g Fe(NO_3)_2
<em>Step 3</em>. Calculate the <em>moles of Fe(NO_3)_2
</em>
Moles of Fe(NO_3)_2
= 230.3 g Fe(NO_3)_2 × [1 mol Fe(NO_3)_2/179.85 g Fe(NO_3)_2]
= 1.280 mol Fe(NO_3)_2
<em>Step 4</em>. Calculate the <em>moles of Fe
</em>
Moles of Fe = 1.280 mol Fe(NO_3)_2 × (3 mol Fe/3 mol Fe(NO_3)_2)
= 1.280 mol Fe
<em>Step 5</em>. Calculate the <em>mass of Fe</em>
Mass of Fe = 1.280 mol Fe × (55.845 g Fe/1 mol Fe) = 71.5 g Fe
A polar bond is when the charge distribution between two atoms is unequal whereas in a polar molecule the charge distribution is not symmetric
