Ethanol is non-toxic, water soluble and biodegradable substance containing 35% oxygen, Ethanol blended fuel contains more oxygen gives more complete fuel combustion and reducing harmful tailpipe emissions. Ethanol displaces toxic gasoline components like benzene, a carcinogen.
Answer is potassium and sodium. They are in the same group and that means they have the same properties. They are all alkali metals
Answer is: 53 milliliters of KOH are required.
Balanced chemical reaction:
2KOH(aq) + H₂SO₄(aq) → 2H₂O(l) + K₂SO₄(aq).
N(KOH) = 0.0050 N; normality of potassium hydroxide solution.
V(H₂SO₄) = 53 mL; volume of sulfuric acid.
N(H₂SO₄) = 0.0050 N; normality of sulfuric acid.
Na·Va = Nb·Vb.
0.0050 N · 53 mL = 0.0050 N · V(KOH).
V(KOH) = 53 mL; volume of potassium hydroxide solution.
