On the periodic table, a group of elements is a column of elements. These columns are also known as families, which indicates that the elements within a group will share certain characteristics. One of these characteristics is the number of valence electrons, or the electrons on the outermost orbit of an atom. So, any element within the same group will have the same number of valence electrons, which will then lead to other shared characteristics, such as chemical properties (how an atom reacts during a chemical reaction, for example).

Question: In our Limiting Reactant lab, we started with an unknown mixture of two reactants, zinc sulfate and sodium phosphate, that reacted in the experiment according to the following equation: 3 ZnSO: (aq) + 2 Na3PO4 (aq) ? Zn (PO4)2 (s) + 3 Na?SO4 (aq) Realistically, some solid was lost in the experiment, so assume 99.0% yield for the purpose of your calculations. Include definitions, explanations, discussion of limiting reactant and percent yield in your response. Use this student's lab data to calculate the percentage of Sodium Phosphate and Zinc Sulfate in the unknown mixture: Mass of unknown mixture of reactants: Mass of solid precipitate collected: Qualitative test determined limiting reactant: 1.983 g 0.759 g Na PO, made the supernatant cloudy
