Sodium Water Reaction – Explanation When sodium (Na) is added to water (H₂O), it causes a highly exothermic chemical reaction, producing: Sodium hydroxide (NaOH) – a strong base Hydrogen gas (H₂) – which may ignite or even explode Heat – often enough to ignite the hydrogen gas 💥 Balanced Chemical Equation: 2Na 2H₂O → 2NaOH H₂↑ heat 🔬 What You Observe: Sodium floats and moves rapidly on water It fizzes and releases gas Heat is released It may catch fire with an orange or yellow flame A small ex

THE WATER CYCLE The water cycle, also known as the hydrological cycle, is the continuous movement of water on, above, and below the surface of the Earth. It plays a critical role in shaping geological processes, regulating climate, and sustaining ecosystems. The cycle ensures that water is constantly recycled between the atmosphere, lithosphere, hydrosphere, and biosphere. MAIN PROCESSES IN THE WATER CYCLE 1. EVAPORATION When the sun heats up water from oceans, rivers, and lakes, it changes into
