The Law of Conservation of Mass is like saying that when you're cooking, you always end up with the same amount of stuff you started with, just mixed up or changed in appearance. If you have a bunch of ingredients like eggs, flour, sugar, and butter to make cookies, you can't end up with more or less than what those ingredients weighed at the beginning. Even if the cookies look and taste different from the raw ingredients, if you weighed them, they would still have the same total weight as the eggs, flour, sugar, and butter you started with. Nothing gets lost or magically appears out of nowhere; it just changes form.

The Law of Conservation of Mass says that matter is neither created nor destroyed, only rearranged. If you start with a certain amount of stuff, you'll end up with that same amount after any process or reaction.
Explain how a balanced equation illustrates the Law of Conservation of Mass. In simple terms.
A balanced equation in chemistry is like a recipe that shows exactly what and how much you need to make something without any leftovers. Each side of the equation has the same number of atoms for each element. This shows that all the stuff you start with gets used up perfectly to make the end product, following the Law of Conservation of Mass. Nothing is wasted or missing; it's all accounted for in the equation, just like making sure you've used all your ingredients when you finish cooking.
Shorter please
A balanced equation has the same number of each type of atom on both sides. It shows that in a chemical reaction, the amount of matter stays the same because the atoms are just rearranged, not created or destroyed.
Are the Law of Conservation of Matter and the Law of Conservation of Mass the same or different? Explain your answer.
The Law of Conservation of Matter and the Law of Conservation of Mass are essentially the same concept described with different words: matter and mass. Both laws state that in a closed system, the total amount of matter or mass remains constant during any chemical reaction; it is neither created nor destroyed but simply transformed or rearranged. The difference in terminology usually comes down to context—'mass' is a more precise term used in physics to quantify the amount of matter in an object, while 'matter' is a broader term used to refer to anything that has mass and occupies space. Despite this slight difference, when discussing chemical reactions and processes, the two terms are often used interchangeably.
In simple terms
The Law of Conservation of Matter and the Law of Conservation of Mass are really just two ways of saying the same thing: no matter or mass is lost or gained in a chemical reaction; it just changes from one form to another. The words 'matter' and 'mass' are sometimes used differently, but in this case, they mean the same thing.
Give an example of a physical change supporting the Law of Conservation of Matter. In simple terms.
Think about melting an ice cube. When an ice cube melts, it changes from a solid to a liquid—water. But even though it looks different, the amount of water is the same as the amount of ice you started with. Nothing is lost. This shows the Law of Conservation of Matter: the matter (water) is still there, just in a different form.
Shorter please
Melting ice is a good example. The ice turns into water, but the amount of water is exactly the same as the ice it came from. Matter isn't lost; it just changes shape.
Give an example of a chemical change supporting the Law of Conservation of Matter. In simple terms.
Burning wood is an example of a chemical change. When wood burns, it turns into ashes, heat, and gases like carbon dioxide and water vapor. Even though the wood changes form and seems to disappear, if you could collect all the ashes, heat, and gases, they would weigh the same as the original wood. This is because in a chemical change, the matter is transformed but not lost, supporting the Law of Conservation of Matter.
Make it shorter
Burning wood transforms it into ash, gases, and heat, but if you add up the weight of all these new products, it matches the weight of the original wood. This demonstrates that matter is conserved in a chemical change.
