Rosa wants to know if energy is absorbed or released when baking soda and vinegar are combined? How can she tell?
Vinegar and baking soda fizzes when combined.
Is energy released or absorbed?
I have noo idea !! Help!!!!
Rosa can determine whether energy is absorbed or released when baking soda and vinegar are combined by conducting an experiment and making observations. Here's how she can do it:
1. Gather materials: Baking soda, vinegar, a clear glass or container, and a thermometer (optional).
2. Add a small amount of baking soda to the glass or container.
3. Slowly pour vinegar into the container containing baking soda.
4. Observe the reaction between the two substances carefully. Look for any changes in temperature, appearance, or any other observable characteristics.
5. If Rosa notices the container becoming warm or hot, it suggests that energy is being released. This is known as an exothermic reaction. On the other hand, if the container feels cool or if Rosa observes any signs of energy being absorbed, it suggests an endothermic reaction, where energy is taken in.
6. If Rosa wants to be more precise, she can use a thermometer to measure temperature changes more accurately. If the temperature increases, it indicates energy release, while a decrease in temperature suggests energy absorption.
By conducting this experiment and making careful observations, Rosa can determine whether energy is absorbed or released when baking soda and vinegar are combined.
