Notable Formulas

1. Law of Conservation of Mass

$\text{Mass of Reactants} = \text{Mass of Products}$

• History: Proposed by Antoine Lavoisier in the 1780s, establishing chemistry as a quantitative science.
• Application: Ensures balanced equations in reactions like combustion or synthesis.
• Example: For $C + O_2 \rightarrow CO_2$, mass is conserved (12 g C + 32 g O₂ = 44 g CO₂).

2. Avogadro’s Law

$V \propto n \quad \text{or} \quad \frac{V}{n} = \text{constant}$

• History: Formulated by Amedeo Avogadro in 1811, linking gas volume to moles.
• Application: Used in gas stoichiometry, e.g., calculating volumes in reactions.
• Example: 1 mole of any gas occupies 22.4 L at STP (0°C, 1 atm).

3. E = mc²

$E = mc^2$

• History: Introduced by Albert Einstein in 1905 as part of special relativity.
• Application: Explains energy release in nuclear reactions, relevant to radiochemistry.
• Example: Fission of 1 g of uranium-235 releases ~8.99 × 10¹⁰ J.

4. Ideal Gas Law

$PV = nRT$

• History: Combined laws from Boyle, Charles, and Avogadro, formalized by Émile Clapeyron.
• Application: Predicts gas behavior in industrial processes like ammonia synthesis.
• Example: Calculate volume of 2 moles of gas at 1 atm, 273 K: ( V = \frac{2 \times 0.0821 \times 273}{1} \approx 44.8 ) L.

Historical Context

These formulas emerged from centuries of experimentation:

• Lavoisier’s Work: Laid the foundation for modern chemistry by debunking phlogiston theory.
• Avogadro’s Contribution: Resolved debates about molecular composition, leading to the mole concept.
• Einstein’s Breakthrough: Revolutionized energy concepts, impacting nuclear chemistry.

Real-World Impact

• Industry: Ideal Gas Law guides gas storage and transport.
• Energy: E = mc² informs nuclear power and radiochemistry.
• Education: These formulas are core to chemistry curricula worldwide.
