Welcome! Today we are going to explore how substances transform into entirely new things through the magic of chemical reactions.
In science, a chemical reaction happens when one or more substances change into completely new substances with different properties. The starting ingredients are called reactants, and the final results are called products.
Think of it like baking a cake! The flour, sugar, and eggs are the reactants. Once they react in the heat of the oven, they chemically combine to form a delicious product: a cake, which cannot be easily turned back into eggs or flour.
During a reaction, chemical bonds between atoms are broken and new bonds are made. The atoms themselves don't disappear; they just get rearranged into new partnerships, like dancers swapping partners on a dance floor.
When iron metal is left outside, it reacts with oxygen gas in the air to form rust (iron oxide). Identify the reactants and the product in this chemical reaction.
- Identify the starting materials that are reacting together. Here, iron metal and oxygen gas are the initial substances.
- Label these starting materials as the 'reactants'. So, the reactants are Iron and Oxygen.
- Identify the new substance that is formed as a result of the reaction. Here, rust (iron oxide) is created.
- Label this new substance as the 'product'. So, the product is Rust (iron oxide).
