Final answer:
The type of mixing bowls that can cause hydrogen peroxide to weaken are B. metal.
Step-by-step explanation:
When hydrogen peroxide comes into contact with metal, it can undergo a reaction called catalytic decomposition in which the metal acts as a catalyst, causing the hydrogen peroxide to break down into water and oxygen gas more quickly. This reaction can weaken the concentration of hydrogen peroxide.
On the other hand, glass, plastic, and ceramic bowls generally do not cause hydrogen peroxide to weaken significantly. While glass and ceramic do undergo thermal expansion and can break if exposed to rapid temperature changes, they do not catalyze the decomposition of hydrogen peroxide like metal does. Plastic bowls, especially those made of polycarbonate, should also not be used to mix hydrogen peroxide due to the potential for the plastic to break down over time at high temperatures.
In conclusion, metal mixing bowls can cause hydrogen peroxide to weaken due to the catalytic decomposition reaction they facilitate. Glass, plastic, and ceramic bowls generally do not significantly affect the strength of hydrogen peroxide. The correct answer is B. metal
