Let’s Do Science: Molecule Building!! This is how scientists write a chemical reaction. Do you remember how we saw a chemical reaction when we combined 1) vinegar and chalk, 2) vinegar and sand, 3) vinegar and crab shell, 4) vinegar + cone snail shell? The bubbles that we saw were carbon dioxide (Co2) being released from the calcium carbonate (CaCo3)! Use this model to replicate the chemical reaction with the materials you were given in class.
