1.) Explain why the following substances are added to soil by gardeners and farmers. a.) Lime CaO It increases the pH of soil.Soil that is too acidic presents two different problems for crops. First‚ the amount of necessary minerals in the soil such as potassium and calcium decreases. Second‚ aluminum and manganese levels increase to potentially toxic levels below a pH of roughly 5.5.Calcium oxide‚ addresses the problem. It reacts in water to release calcium ions and hydroxide ions‚ which raise

Sustainable Chemistry Terry Collins* Chemistry has an important role to play in achieving a sustainable civilization on Earth. The present economy remains utterly dependent on a massive inward flow of natural resources that includes vast amounts of nonrenewables. This is followed by a reverse flow of economically spent matter back to the ecosphere. Chemical sustainability problems are determined largely by these economy-ecosphere materials flows (see the figure‚ below)‚ which current chemistry education
