* Empirical and Quantitative: Chemistry relies heavily on experiments and measurements. Its principles are based on quantifiable observations and data analysis.

* Objective and Testable: Chemical theories and laws are rigorously tested and verified through experimentation. The results are not subjective or open to interpretation.

* Predictive Power: Chemistry has a high predictive power. Based on established principles, chemists can predict the outcome of reactions or the properties of new substances.

* Mathematical Framework: Chemistry uses a strong mathematical framework to describe its principles and analyze experimental data.

While some areas of chemistry might involve more theoretical or conceptual aspects, the core of the discipline is grounded in empirical observation and rigorous experimentation. This is what distinguishes it as a hard science.

It's important to note that the distinction between "hard" and "soft" sciences is not always clear-cut and can be debated. Some argue that the terms are outdated and unhelpful. Ultimately, both hard and soft sciences contribute to our understanding of the world, and the methods and approaches used in each are valuable in their own right.
