Explanation:
Lime is added to lower the acidity of lakes when pH levels go too low.
Acidic environment is harmful to aquatic ecosystems. Acidity causes some minerals, such as phosphorus and calcium, in the water to become unavailable to aquatic organisms like plants and fishes ( This means the water hardness is reduced). The low nutrients cause stress and death in the aquatic environment lowering biodiversity. Applying lime raises the pH to neutral levels and improves the health of the aquatic life in the lake. This also improves economic activities in the lake like fishing.

Answer:
Percent yield is 25%
Explanation:
Information given is
Actual yield is 25 g
But the yield should be 100 g
The percent yield is defined as the ratio of the actual yield and the predicted yield it means that out of the predicted yield what percentage of the actual yield is obtained
∴ Percent yield = (Actual yield ÷ Predicted yield) × 100
In case of the given problem the percent yield will be
(25÷100) × 100 = 25%
∴ Percent yield = 25%
