a student is completing a lab investigation to prove that mass is conserved during the chemical reaction shown. solution x + solid y → solution z. the steps in the lab procedure are listed. select the step that proves the conservation of mass.\na step 1. measure and record the mass of solution x, solid y, and a beaker.\nb step 2. combine solution x and solid y in the beaker and measure the mass of the beaker now containing solution z.\nc step 3. subtract the mass of the beaker from the mass of solution z and the beaker (from step 2).\nd step 4. compare the mass of solution x and solid y to the mass of solution z.

Answer

Explanation:

Step1: Understand conservation of mass

Conservation of mass means mass before = mass after.

Step2: Analyze each step

Steps A - C are just intermediate measurements. Step D compares mass before (Solution X + Solid Y) and mass after (Solution Z).

Answer:

D. Compare the mass of Solution X and Solid Y to the mass of Solution Z
