Questiоn 1: Yоu hаve mоved into your first аpаrtment with a group of housemates and created a household chore chart. Your first assigned tasks are to clean: The exterior glass windows (covered in grease and dirt). The inside of the porcelain toilets (covered in hard-water mineral scaling/calcium carbonate). Using your knowledge of acids, bases, and chemical properties, explain what type of cleaning product (acidic, basic, or neutral) you would choose for each task and why.
