Properties of the original substances hydrogen peroxide and hair
Hydrogen Peroxide:
1. Chemical Formula: H2O2
2. Physical State: Colorless liquid
3. Odor: Characteristic slightly pungent odor
4. Solubility: Readily soluble in water
5. Density: 1.44 g/cm3
6. Boiling Point: 150.2 °C (302.4 °F)
7. Melting Point: -0.43 °C (31.23 °F)
8. Reactivity: It is a powerful oxidizing agent and can react vigorously with many substances, including organic compounds.
9. Stability: Hydrogen peroxide is unstable and decomposes slowly over time, especially when exposed to light and heat.
10. Uses: Hydrogen peroxide is commonly used as a disinfectant, bleach, and as an oxidizer in various applications such as rocket fuel.
Hair:
1. Composition: Mainly composed of a protein called keratin.
2. Physical State: Solid (strands of hair)
3. Color: Can be naturally occurring or artificially colored (due to pigments called melanin).
4. Texture: Varies from person to person and can be straight, wavy, or curly.
5. Elasticity: Can stretch and return to its original shape without breaking.
6. Strength: Hair is relatively strong but can be damaged or weakened by various factors like heat, chemicals, and rough handling.
7. Growth: Hair grows at an average rate of about 0.5 inches (1.25 cm) per month.
8. Sensitivity: Hair follicles are sensitive to hormonal changes, and certain conditions can cause hair loss or thinning.
9. Insulation: Hair acts as an insulator, helping to regulate body temperature.
10. Protection: Hair, especially scalp hair, provides protection against UV radiation, dust, and harmful environmental factors.
