Social Problem-Unemployment .pptx notes for Physiotherapy StudentsDrNidhiAgarwal

Unemployment is a major social problem, by which not only rural population have suffered but also urban population are suffered while they are literate having good qualification.The evil consequences like poverty, frustration, revolution result in crimes and social disorganization. Therefore, it is necessary that all efforts be made to have maximum. employment facilities. The Government of India has already announced that the question of payment of unemployment allowance cannot be considered in India

CBSE - Grade 8 - Science - Chemistry - Metals and Non Metals - WorksheetSritoma Majumder

Introduction All the materials around us are made up of elements. These elements can be broadly divided into two major groups: Metals Non-Metals Each group has its own unique physical and chemical properties. Let's understand them one by one. Physical Properties 1. Appearance Metals: Shiny (lustrous). Example: gold, silver, copper. Non-metals: Dull appearance (except iodine, which is shiny). 2. Hardness Metals: Generally hard. Example: iron. Non-metals: Usually soft (except diamond, a form of carbon, which is very hard). 3. State Metals: Mostly solids at room temperature (except mercury, which is a liquid). Non-metals: Can be solids, liquids, or gases. Example: oxygen (gas), bromine (liquid), sulphur (solid). 4. Malleability Metals: Can be hammered into thin sheets (malleable). Non-metals: Not malleable. They break when hammered (brittle). 5. Ductility Metals: Can be drawn into wires (ductile). Non-metals: Not ductile. 6. Conductivity Metals: Good conductors of heat and electricity. Non-metals: Poor conductors (except graphite, which is a good conductor). 7. Sonorous Nature Metals: Produce a ringing sound when struck. Non-metals: Do not produce sound. Chemical Properties 1. Reaction with Oxygen Metals react with oxygen to form metal oxides. These metal oxides are usually basic. Non-metals react with oxygen to form non-metallic oxides. These oxides are usually acidic. 2. Reaction with Water Metals: Some react vigorously (e.g., sodium). Some react slowly (e.g., iron). Some do not react at all (e.g., gold, silver). Non-metals: Generally do not react with water. 3. Reaction with Acids Metals react with acids to produce salt and hydrogen gas. Non-metals: Do not react with acids. 4. Reaction with Bases Some non-metals react with bases to form salts, but this is rare. Metals generally do not react with bases directly (except amphoteric metals like aluminum and zinc). Displacement Reaction More reactive metals can displace less reactive metals from their salt solutions. Uses of Metals Iron: Making machines, tools, and buildings. Aluminum: Used in aircraft, utensils. Copper: Electrical wires. Gold and Silver: Jewelry. Zinc: Coating iron to prevent rusting (galvanization). Uses of Non-Metals Oxygen: Breathing. Nitrogen: Fertilizers. Chlorine: Water purification. Carbon: Fuel (coal), steel-making (coke). Iodine: Medicines. Alloys An alloy is a mixture of metals or a metal with a non-metal. Alloys have improved properties like strength, resistance to rusting.

K12 Tableau Tuesday - Algebra Equity and Access in Atlanta Public Schoolsdogden2

Algebra 1 is often described as a “gateway” class, a pivotal moment that can shape the rest of a student’s K–12 education. Early access is key: successfully completing Algebra 1 in middle school allows students to complete advanced math and science coursework in high school, which research shows lead to higher wages and lower rates of unemployment in adulthood. Learn how The Atlanta Public Schools is using their data to create a more equitable enrollment in middle school Algebra classes.
