Interpretation Introduction
Interpretation: An explanation regarding the given statements is to be stated.
Concept introduction: The power plants that burn large amounts of coal use scrubbers for eliminating sulfur emissions.
Lime is added to the soil because of its positive affects that increase the fertility of the soil.
To determine: An explanation regarding the given statement, “A gardener mixes lime
(CaO) into the soil of his garden”.
The addition of lime
(CaO) into the soil increases the
pH of the soil making it less acidic.
