Accepted Answer

If it completes 2 cycles in 10 seconds, then each cycle takes 5 seconds. That's the period.Frequency = 1 / period = 1 / 5 sec = 0.2 per sec = 0.2 Hz.

Suggested Answer

period 5 sec = 1 cyclef = 1/period.2

Objective: Apply the concepts of mole and stoichiometry. 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 Na₂SO4 (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
