Answer:
C) the law of conservation of matter
Step-by-step explanation:
The law of conservation of matter, also known as the law of conservation of mass, states that matter cannot be created or destroyed in a chemical reaction. This means that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products.
In the context of recycling, this law means that the materials used to make a product can be reused or transformed into new products, rather than being discarded as waste. When materials are recycled, they are not destroyed or eliminated, but rather they are converted into new forms or combined with other materials to create something new. By recycling materials, we are able to reduce the amount of waste that goes into landfills or is incinerated, and we can also conserve natural resources by using fewer raw materials to make new products. Overall, the law of conservation of matter provides a scientific basis for the practice of recycling, and highlights the importance of sustainable resource use and waste reduction.
