- "Let's start with a simple reaction. Here we have vinegar (acetic acid) and baking soda (sodium bicarbonate)."
- "What happens when we mix them?"
- Vinegar
- Baking Soda
- Deslizar: 3
- "Watch closely as we mix them."
- Vinegar
- Baking Soda
- Deslizar: 4
- "That's carbon dioxide gas being released. But did the total mass change?"
- "Wow, look at all those bubbles!"
- Baking Soda
- Deslizar: 5
- "Today, we're going to learn about chemical reactions and the law of conservation of mass."
- LAW OF CONSERVATION OF MASS
- "The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction."
- "The mass of the reactants equals the mass of the products."
- Deslizar: 6
- Vinegar + Baking Soda → Carbon Dioxide + Water + Sodium Acetate
- "In our reaction, vinegar and baking soda are the reactants."
- "They produce carbon dioxide, water, and sodium acetate as products."
- Deslizar: 7
- CHEMICAL EQUATION:
- NaCHO3 + HC2H3O2 → NaC2H3O2 + CO2 + H20
- "Let's balance the equation."
- "So, the number of atoms of each element is the same on both sides?"
- Deslizar: 8
- CHEMICAL EQUATION:
- NaCHO3 + HC2H3O2 → NaC2H3O2 + CO2 + H20
- "Exactly! Remember, in every chemical reaction, the total mass of the reactants equals the total mass of the products."
- "That makes sense now. Thanks, teacher!"
