General Chemistry Chapter 1 Flashcards

Chlorine is classified as a highly reactive gas, which is an observation.
Law: When elements are arranged in order of increasing atomic mass, their chemical reactivity shows a repeating pattern.
Theory: The reactivity of elements is dependent on the arrangement of their electrons.

The term tripartite refers to something that consists of three distinct parts.

Liquid at room temperature is classified as a physical property.
Colorless is also a physical property.
Mixing with water indicates a physical property.
Density given as 0.79 g/mL is a physical property.
Flammability is a significant chemical property.
Gas at room temperature is classified as a physical property.
A bluish color is a physical property.
A pungent odor is a physical property.
Describing an element as very reactive denotes a chemical property.
Decomposition upon exposure to ultraviolet light is considered a chemical property.

The boiling point of water at sea level is 212°F, which converts to 100°C using the formula: ( T(°C) = \frac{(F - 32)}{1.8} ).
Room temperature of 25°C converts to approximately 298 K using: ( K = C + 273.15 ).
Absolute zero, defined as 0.00 K, converts to -459.67°F. Direct conversion is not possible; first convert to Celsius then to Fahrenheit.
The average temperature of the universe at 2.735 K converts to -270.42°C using the formula: ( C = K - 273.15 ).
