Answer:
0.075 moles of product formed.
Explanation:
Given data:
Number of moles of oxygen = 0.30 mol
Number of moles of oxygen = 0.15 mol
Number of moles of product formed = ?
Solution:
Chemical equation:
4Na + O₂ → 2Na₂O
Now we will compare the moles of Na₂O with oxygen and sodium.
Na : Na₂O
4 : 2
0.15 : 2/4×0.15 = 0.075 mol
O₂ : Na₂O
1 : 2
0.30 : 2/1×0.30 = 0.6 mol
Less number of moles of Na₂O are produced by sodium thus it will limit the yield of Na₂O and act as limiting reactant while oxygen is in excess.
Answer:
A
Explanation:
When a reaction happens some of the reactants mass is released as energy so the mass of the product would be less
