Chemical Reactions
Across
- 2. Anything that has mass and occupies space, including solids, liquids, and gases.
- 4. Substances formed as a result of a chemical reaction, existing after the reaction has taken place.
- 8. A measure of the amount of matter in an object, typically measured in grams or kilograms.
- 9. A representation of a chemical reaction that shows equal numbers of each type of atom on both sides, illustrating the conservation of mass.
- 10. A physical system that does not exchange matter with its surroundings, allowing for the conservation of mass during reactions.
Down
- 1. Antoine Lavoisier, a French chemist known as the "Father of Modern Chemistry," who established the law of conservation of mass in the late 18th century.
- 3. A process in which reactants are transformed into products through the rearrangement of atoms.
- 5. The principle of maintaining a quantity in a closed system; in this context, it refers to mass not being created or destroyed in a chemical reaction.
- 6. The branch of chemistry that deals with the quantitative relationships of the reactants and products in chemical reactions.
- 7. Substances that undergo a chemical change in a reaction, present before the reaction occurs.
