Since I can't upload files or documents, I can help you draft a written paragraph supporting your claim about chemical reactions. Here's a suggested paragraph you can use for your Matter Interactions Portfolio:
Chemical reactions are fundamental processes that involve the transformation of substances through the breaking and forming of chemical bonds. These interactions are characterized by the rearrangement of atoms and often result in the production of new substances with distinct properties, such as changes in color, temperature, or state of matter. For example, the combustion of hydrogen gas in the presence of oxygen produces water, a reaction that releases energy in the form of heat and light. This evidence supports the claim that chemical reactions play a crucial role in both natural processes and human-made systems. Understanding these interactions not only helps in elucidating the nature of matter but also in harnessing chemical reactions for practical applications, ranging from energy production to pharmaceuticals.
