Here is the transcription of the text for an educational website:---**Chemistry Problem: Precipitation and Mass Calculation**2) Calcium nitrate is dissolved in water with an excess of sodium sulfate to make sodium nitrate and solid calcium sulfate.a) Write the balanced equation.b) If the mass of precipitate that forms is 0.5000 g, what was the mass of calcium ions (Ca²⁺) in the original solution?c) If the original sample has a mass of 0.99 g, what percent by mass of the unknown compound is calcium?---This problem involves dissolving calcium nitrate in water and reacting it with sodium sulfate, leading to precipitation. Students are asked to write the balanced chemical equation, calculate the mass of calcium ions based on the precipitate formed, and determine the percentage of calcium in the original sample.No graphs or diagrams are present in the image. If any data tables or graphs were provided, they would typically be used to display numerical data or visualize the relationship between variables in the experiment.
