Products in chemistry are like the things you have after you make something. For example, imagine you are making a cake. The ingredients you use, like eggs, sugar, and flour, are the reactants. When you mix them all together and bake the cake, the cake you end up with is the product.
In chemistry, reactants come together and react to form new things. These new things are the products. Products can be a gas, solid, or liquid, depending on what kind of reaction happened.
Think of it like playing with blocks. You have some blocks, and you stack them up to make a tower. The tower is your product, and the blocks you used are the reactants. Depending on how you stacked the blocks, the tower might look different - it could be a tall tower, a short tower, or even a tower with a funny shape.
Similarly, in chemistry, the products can look different depending on what reactants were used and how they reacted. Scientists use products to study how reactions happen and to make new things that can help people in different ways.
