I've tried to find the grams of the excess reactant, but it don't know what I'm calculating wrong.
Pure magnesium metal is often found as ribbons and can easily burn in the presence of oxygen. When magnesium ribbon burns with oxygen, bright, white light and a white, powdery product are formed.
Enter the balanced chemical equation for this reaction. Be sure to include all physical states.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
