Study Notes
Symbols of Elements
- Iron is represented by the symbol Fe.
- Mercury corresponds to the symbol Hg.
- Gold is denoted by the symbol Au.
States of Matter
- Liquids do not have a fixed shape and take the shape of their container.
- A solid retains its shape; the state represented in an unspecified image is a solid.
Volume Calculation
- Volume of a box (4.0 cm x 8.5 cm x 2.0 cm) is 68 mL.
- For a box measuring 2.5 cm x 3.0 cm x 4.0 cm, the volume is 30 mL (0.030 L).
- Volume of a box measuring 3.5 cm x 4.0 cm x 8.0 cm is 112 mL (0.112 L).
Scientific Notation and Significant Figures
- The number 625,000 in scientific notation is expressed as 6.25 × 10^5.
- The product of ( (6.45 × 10^5) × (1.2 × 10^4) ) is 7.7 × 10^9.
- The product of ( (8.2 × 10^{-3}) × (2.84 × 10^5) ) results in 2.3 × 10^3.
- For ( (6.1 × 10^4) × (3312) ), the scientific notation is 2.0 × 10^8.
Measurement and Calculation
- The subtraction ( 28.645 g – 22.105 g ) yields 6.540 g when considering significant figures.
- The sum ( 56.234 g + 0.0021 g ) results in 56.236 g.
- Adding ( 102.5 mL + 6.55 mL ) gives 109.0 mL.
Temperature Change
- When the temperature of water decreases from 22°C to -25°C, the decrease is 47°C, which corresponds to 320 K.
Physical vs. Chemical Properties
- Physical properties include boiling points and states at room temperature; examples include:
- Acetone boiling at 56°C.
- Helium being a gas at room temperature.
- Chemical properties, such as the rusting of iron, illustrate chemical reactions, differing from changes like the dissolving of sugar which is physical.
Changes in Matter
- Dissolving Kool-Aid in water shows a physical change.
- Burning magnesium demonstrates a chemical change, while aluminum turning white indicates a surface reaction rather than a change in composition.
Forms of Energy
- The text hints at various energy forms, with a query regarding one that is not recognized as energy, indicating a thematic exploration of energy types.
