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

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" »

Core Linguistic Concepts

Determiners and Modifiers

The **Zero Determiner** refers to indeterminacy, often seen in phrases like "human beings who are rational."

• **Verb vs. Adjective:** Verbs often use the continuous form (e.g., *be + -ing*). Adjectives allow gradation (e.g., *very entertaining*).
• **Adverb vs. Adjective:** Adverbs modify verbs; adjectives modify nouns.

English Verb Classification

Main Verb Types

Verbs are classified based on their complementation patterns:

• **Intransitive (H):** Requires only the head/subject (e.g., *She signed, I am eating*).
• **Copulative (H + PCS):** Links the head/subject to a Predicate Complement of the Subject (e.g., *Turned red, seems an interesting idea, in good condition*).
• **Transitive (H + DO):** Requires a Direct

SCR Construction

A thyristor, or SCR, consists of four P-N-P-N layers and has three PN junctions (J1, J2, J3) in series. It has three terminals: Anode, Cathode, and Gate. The Gate terminal is attached to the P-type layer near the Cathode terminal. The two-transistor model shows that an SCR is a combination of one PNP transistor and one NPN transistor.

The emitter of the PNP transistor is taken as the Anode terminal, the emitter of the NPN transistor is taken as the Cathode, and the base of the PNP is taken as the Gate terminal. The base of the PNP is connected to the collector of the NPN, and the collector of the PNP is connected to the base of the NPN transistor.

Advantages of SCRs:

• Easy to turn ON
• Can handle large voltage, current, and power
• Possible
