s students face in Unit 5, and how can teachers address them? Students often struggle with the abstract nature of energy and momentum concepts. Teachers can address this by using visual models, analogies, and interactive simulations to make these ideas more concrete. How does Model
ext{CO}_2 + 4\text{H}_2\text{O} \] Explanation: Start with the carbon atoms: 3 in propane (\(\text{C}_3\text{H}_8\)), so produce 3 \(\text{CO}_2\) molecules to balance carbon. Then, hydrogen atoms: 8 in propane, so produce 4 \(\text{H}_2\text{O}\) molecules to balance hydrog
