B. breaking a mirror
C. cutting wood
D. popping popcorn
Thanks :)
Popping popcorn action will result in a product with new chemical properties, therefore the correct answer for the given problem is option D.
In a chemical reaction, one or more components referred to as reactants—are changed into one or more other substances—also referred to as byproducts.
A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
The energy of the reactant is greater than the energy of the product because the extra energy is released during an exothermic reaction.
Popcorn would be the best choice since it would transform the pre-popped kernels into something else whereas the other options would merely change their outward look.
Thus, popping popcorn action will result in a product with new chemical properties, therefore the correct answer for the given problem is option D

Explanation:
i think so anyway.
Answer:
Explanation:
AI-generated answer
A hypothesis is a statement that predicts what will be observed in an investigation. It is based on background research performed by the scientist and is usually written in an if-then format that describes the proposed relationship between variables. Therefore, all of the statements listed are true about hypotheses.
1. A hypothesis is a question a scientist wants to research.
2. A hypothesis is a statement that predicts what will be observed in an investigation.
3. A hypothesis is based on background research performed by the scientist.
4. A hypothesis is usually written in an if-then format that describes the proposed relationship between variables.
