Final answer:
In a chemical reaction compared to baking a cake, ingredients such as flour, sugar, milk, and eggs represent the reactants. Option D is correct.
Step-by-step explanation:
If likening a chemical reaction to baking a cake, the "ingredients" such as flour, sugar, milk, and eggs would be analogous to reactants in a chemical reaction. Reactants are the starting materials, similar to ingredients in baking, which undergo a chemical change to produce new substances called products.
In the context of baking a cake, the flour, sugar, milk, and eggs are mixed together (reactants) in a certain process (reaction) to create the cake (product).
For example, if we think about baking chocolate chip cookies, the reactants would be flour, butter, sugar, vanilla, baking soda, salt, egg, and chocolate chips. We mix these ingredients in a bowl (reaction vessel), bake them, and the products of this process are the cookies.
This illustrates the role of reactants and products in a chemical reaction, demonstrating the conservation of mass—what you start with (reactants) is transformed into the end product (cookies) without loss of material, only a change in form.
These reactants undergo a reaction to produce new substances called products, similar to how ingredients are mixed to make a cake.
