Wastewater having 22 mg/l dissolved phosphorous (po43−) is treated chemicaly with ferric sulfate ((fe2(so4)3) (concentrated solution of 165 gr/l as fe). how much stock solution (volume in ml) of ferric sulfate is needed per a liter of water treated to achieve 100% po43− removal? how much solids (on a dry basis) are generated in the process per a million gallons of water treated? (show your calculations and provide answers in ml (for volume) and kg (for solids))

Choose all the answers that apply. ionic compounds dissolve easily in water do not dissolve in water have low melting points have high melting points conduct electricity when melted

What is the mass of phosphorous in a 51-kg person

In a modern periodic table, there are seven periods. a period is any horizontal row of the periodic table, and the elements in a period have consecutive atomic numbers. a group is any vertical column in the periodic table, and there are 18 such groups. groups 3–12, also known as the “b” group elements, are called transition metals. groups 1–2 and 13–18, also known as the “a” group elements, are sometimes called the main groups. metals are characterized by malleability, ductility, conductivity, and a tendency to lose electrons. main group metals are found in groups 1 and 2. nonmetallic elements fall on the right-hand side of the periodic table, that is, groups 13–18. nonmetals have the tendency to gain electrons and are generally brittle. they can be solids, liquids, or gasses at room temperature. now, label the areas of the modern periodic table using the above information. drag the appropriate labels to their respective targets.
