Question

1. make a model to show that mass is conserved. what is the mass?, what might the product look like? 2g 3g 2g + 3g red bricks__ blue bricks what is the total mass of the product?__

Explanation:

Step1: Count red bricks

Count = 3

Step2: Count blue bricks

Count = 2

Step3: Calculate total mass

Total mass = $(3 \times 2\mathrm{g}) + (2 \times 3\mathrm{g}) = 6\mathrm{g} + 6\mathrm{g} = 12\mathrm{g}$

Step4: Describe product appearance

Combine all 5 bricks into one connected structure (e.g., a single long block made by attaching all the red and blue bricks together, keeping their individual masses accounted for).

Answer:

Red Bricks: 3
Blue Bricks: 2
What might the product look like? A single connected structure made by joining all 3 red 2g bricks and 2 blue 3g bricks together (e.g., a long chain or combined block where all pieces are attached).
What is the total mass of the product? $12\mathrm{g}$
