Reset Additional Quiz Represent as Simplest Fraction Handout for Grade 8-10 Students Key Points Converting decimals to simplest fractions involves turning terminating decimals (e.g., 0.75) and repeating decimals (e.g., 0.666...) into fractions and simplifying them. Terminating decimals are converted by writing them as fractions with denominators as powers of 10, then simplifying. Repeating decimals use an algebraic method to eliminate the repeating part. Simplifying fractions requires finding the greatest common divisor (GCD) to reduce the fraction to its simplest form. Converting Terminating Decimals Terminating decimals, like 0.75, end after a finite number of dig...

Quiz 1:   Fullscreen Mode 🧪 METALS & REACTIVITY SERIES: Complete Theory & Formulas 🔬 I. FUNDAMENTAL THEORIES OF METALS 1.1 Electronic Theory of Metallic Bonding Sea of Electrons Model: Metals consist of a lattice of positive metal ions surrounded by a "sea" of delocalized electrons. This explains conductivity, malleability, and ductility. Metal Atom → Metal Ion⁺ + e⁻ M(s) → M⁺(aq) + e⁻ (general form) 1.2 Density Theory & Formula Density is a fundamental physical property that measures mass per unit volume. Density = Mass ÷ Volume ρ = m/V (g/cm³ or kg/m³) High Density Examples Gold: 19.3 g/cm³ Lead: 11.4 g/cm³ Copper: 8.9 g/cm³ ...

Quiz Using Moles - Complete Theory & Formulas Cambridge IGCSE Chemistry - Grade 9 1. The Mole Concept - Core Theory Definition of a Mole A mole is the amount of substance that contains as many elementary entities (atoms, molecules, ions) as there are atoms in exactly 12 grams of carbon-12 . Avogadro's Constant N A = 6.022 × 10 23 mol -1 This means 1 mole of any substance contains 6.022 × 10 23 particles Key Principle: One mole of any substance contains the same number of particles, but the mass depends on the type of particle. 2. Fundamental Formulas 2.1 Mole-Mass Relationship Number of moles (n) = Mass (m) ÷ Molar mass (M) n = m/M Mass (g) ...
