named after "Robert Bunsen"‚ is a lab piece equipment that produces a single flame which is used for heating‚sterilization and combustion. Our instructor‚ Dr. Immel‚ provided us with six heavy metals those metals were: Barium‚ Calcium‚ Lithium‚ Potassium‚ Sodium‚ Strontium. My group got a platinum flame loop‚ and decontaminated it with the water beaker filled half way with water. To light the Bunsen burner my group used a striker‚ which Dr. Immel provided. We started off with Barium‚ when Charlotte

Manures The deficiency of plant nutrients and organic matter in the soil is made up by adding manures and fertilizers to the soil of crop-fields. Both manures and fertilizers are major sources of nutrients of plants‚ so they are used in crop production. Besides water CO2 and sunlight plants required no. of elements for their growth. These elements are known as nutrient. Plants get their elements from the salt of these elements present in the soil. But after repeated cultivation of plants soil become
