Everyday Chemistry Quiz – Chemistry at Home

Chemistry is happening all around us, especially at home. Cooking, cleaning, washing and even breathing involve chemical reactions and interactions between molecules.

In the kitchen, baking powder releases gas to make cakes rise, heat browns food through the Maillard reaction and enzymes turn cut apples brown. In the bathroom, soaps and detergents trap oil and dirt so water can wash them away.

Understanding everyday chemistry helps us stay safe and use products wisely, such as never mixing bleach with ammonia, storing batteries properly and wearing sunscreen. It also makes daily life more interesting.
