Water also dissolves non-ionic substances.This is because C2H5OH has a polar Oh and the bond that the water molecules like to hang around. Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. A common example is oil and water.
C is the correct answer.a buffer reacts with the added acid or base which can produce H+ or hydroxide ion,or a kind of removing H+ or hydroxide added to solution.remember that buffers don't prevent additional acid or base from reacting,they react with the additional themselves.the A and D are completely wrong.
Answer:
Percent yield = 82.5
Explanation:
Given data:
Actual yield of N₂ = 275 L
Theoretical yield = 333 L
Percent yield = ?
Solution:
Chemical equation:
4HCl + 6NO → 5N₂ + 6H₂O
Percent yield:
Percent yield = actual yield / theoretical yield × 100
Percent yield = (275 L/ 333 L ) × 100
Percent yield = 0.825× 100
Percent yield = 82.5%
