A Story of Contrasts

The film Witness, directed by Peter Weir, effectively portrays several distinct ideas, including the cultural clash between the Amish and modern society, the romance between the two protagonists, and the theme of good versus evil, highlighting corruption within the police force. These central themes, combined with effective cinematic elements, justify the film's status as a memorable cinematic experience.

The Human Circulatory and Respiratory Systems

Key Components and Functions

1. The Diaphragm's Role in Respiration

The diaphragm separates the thoracic cavity (containing the heart, lungs, and ribs) from the abdominal cavity. It plays a crucial role in respiration. As the diaphragm contracts, the volume of the thoracic cavity increases, drawing air into the lungs.

2. Arteries: Transporting Oxygenated Blood

Arteries are large, thick-walled, muscular blood vessels that carry oxygenated blood away from the heart.

• Pulmonary Arteries: Carry deoxygenated blood from the heart to the lungs.
• Umbilical Arteries: Paired arteries (one for each half of the body) found in the abdominal and pelvic regions. They supply deoxygenated blood from the fetus to the placenta

The Law of Conservation of Mass

Matter cannot be created or destroyed. The number of atoms in the reactants must be the same as the products. Atoms don't appear or disappear, they just rearrange. (Hence why you have to balance out chemical equations)

Balancing Equations

• The subscripts in the chemical formula cannot be changed (The little number beside a formula that is part of it).
• Use coefficients to balance.
• Coefficients multiply the entire compound by that number (4PO = 4P 4O).

Example: N₂+O₂>N₂O = 2N₂+O₂>2N₂O

Balancing Word Equations

• Determine what the reactants and the products are, convert names to chemical formulas. (Individual elements that are diatomic (molecular) will be, S₈, P₄, I₂, Br₂, Cl₂, F₂, O₂, N₂, H₂) If it's not diatomic just

Structure of the Atom

Protons, Electrons, and Neutrons

Protons: Equal to the atomic number

Electrons: Equal to the atomic number

Neutrons: Equal to the atomic mass minus the atomic number

Bohr-Rutherford Diagram

Electron shells: 2, 8, 8, 18, 18, 32

Counting Atoms

Example 1: Na₂CO₃

• Sodium (Na): 2
• Carbon (C): 1
• Oxygen (O): 3

Example 2: 4Al₂(CO₃)₃

• Aluminum (Al): 4 x 2 = 8
• Carbon (C): 3 x 4 = 12
• Oxygen (O): 9 x 4 = 36
• Total: 56

Ions and Ionic Compounds

Ions are atoms that have either lost or gained electrons. While atoms are neutral, ions are charged particles.

Ionic Compounds are a combination of a cation (positive ion) and an anion (negative ion), typically formed between a metal and a nonmetal.

Example: Calcium Chloride (CaCl₂)

Calcium (Ca⁺²) has a charge of +2,... Continue reading "Structure of the Atom, Chemical Reactions, and Acids and Bases" »
