- 3. Chemistry is a big part of our everyday life. Foods we eat, the air we breathe, cleaning chemicals. Our emotions. every object we can see or touch. Happens in the world around us, not just in a lab. INTRODUCTION
- 4. CHEMISTRY HAS IMPORTANT CONTRIBUTION FOR GIVING US: Foods Life saving drug Soaps and detergents Cosmetics Pesticides
- 5. COMMON CHEMICAL COMPOUNDS Water- H2O Soaps- 遺堰遺或或鰻温
- 6. Nail polish -(nitrocellulose) Table Salt- NaCl
- 7. Vinegar- C2 H4 O2 Washing Soda- Na2CO3 .10H2O
- 8. Table Sugar- C12H22 O11 Bleaching Powder- NaClO
- 10. To Neutralise Acid Sodium bicarbonate A luminum hydroxide Magnesium hydroxide CHEMISTRY OF ANTACID
- 11. CHEMICALS IN TALC POWDER talc (magnesium silicate) magnesium, silicon and oxygen Soapy, Slippery & Smoothness
- 12. CHEMICALS IN TOOTHPASTE Prevent Cavities Antibacterial agentFoam due to H2O2
- 13. CHEMICALS IN SHAMPOO Glycol As a Surfactant As a Solvent
- 14. CHEMICALS IN LIPSTICK For Red colour To mask the fragrance of other chemicals Provide structure High melting point Provide lubrication Glossy nature
- 15. CHEMICALS IN NAIL POLISH REMOVER Ethyl lactate Glycerin Water - H2O
- 16. CHEMICALS IN SUNSCREENS INORGANIC CHEMICAL-- ZnO,TiO absorbs & scatter light.UVA -- 320 - 400nm UVB -- 290 - 320nm UVC --290 - 100nm
- 17. CHEMISTRY OF MOISTURIZER Form hydrophobic barrier Skin feel greasy Ex. Vaseline Hydrophilic in nature Draw water from dermis Draw water from atmosphere Form barrier to TEWL Plug gaps weem dead skin cells Provide smooth skin
- 19. CHEMICALS IN CHILLI Burning sensation
- 20. CHEMISTRY OF ROSES FOR RED COLOUR For YELLOW & ORANGE COLOUR
- 21. CHEMISTRY OF MILK Emulsion(Fat +Water) Colloidal suspension of protein Lactose- sugar Fermented by microorganisms Triglycerides Fat soluble vitamins Casein protein form micelles Micelles scatter light milk appea white.
- 22. CHEMICALS IN EGG FOR YELLOW COLOUR Main component of eggshell For eggshell colour Nutrition Against infections Thicken eggwhite
- 26. CHEMISTRY OF INK Help to dissolve dye Help to bind ink with paper
- 27. CHEMISTRY OF FIREWORKS COLOUR? Produce colour Allow to burn. Provide O2 - combustion Holds mixture. Strengthen colour
- 28. FIREWORK BANGS,CRACKLES & WHISTLES Produce flash light & loud bang Compacted gunpowder produces large bang Mixed with Mg-Al alloy Rapid combustion produces crackling effect Tightly packed into tube Produce oscillation in gases Standing waves in tube, produces whistle and effect
- 29. CHEMISTRY INSIDE OUR BODY Approx. 99 % mass of body contains 6 elements -- Oxygen, carbon, hydrogen, nitrogen
- 30. CHEMISTRY OF DIFFERENT COLOUR OF BLOOD
- 31. CHEMISTRY OF BODY FLUID COLOUR Haem contain Iron(redcolour) Blood dries, turn brown Hb oxidise to Methaemoglobin Haem broken into biliverdin Biliverdin converted into Bilirubin Bilirubin oxidise into Urobilin Excreted by kidneys Produce yellow colour of urine Bilirubin reduce into Stercobilin Excreted in the faeces Produce yellow colour of faeces
- 32. ODOUR OF HUMAN WASTE Butanoic,pentanoic - Vomit odour Methanethiol, Hydrogen Sulphide - onion like odour Indole,Skatole - feacal matter odour Ammonia,Trimethylamine-Urine waste odour
- 33. ODOUR OF SOME ITEMS
- 35. CHEMISTRY OF LOVE ATTRACTION - Due to testosterone, estrogen PHEROMONES- individual scent
- 36. FALLING IN LOVE- Due to monoamines (brain chemical) High BP ,heartPleasure feeling Control impulses
- 37. antistress effect. Monogany chemical Cuddle chemical
- 39. WHY SMOKING HARMFUL & CAUSES CANCER ? Tobacco contains approx. 60 carcinogenic compounds like CO, HCN, NH3 & other irritants.
- 40. Tobacco becomes addictive due to nicotine NICOTINE - Alkaloid (organic compound) Increase level of dopamine Responsible for feeling of pleasure
- 42. HOW PLANTS PRODUCE FOOD? PHOTOSYNTHESIS
- 43. HOW FRUITS RIPE?
- 44. WHAT HAPPENS WHEN FOOD GOES INSIDE OUR STOMACH?
- 45. HOW ENERGY IS PRODUCED BY CELLS? Redox reaction
- 46. WHAT HAPPENS WHEN WE STRIKE A MATCH, BURN A CANDLE OR BUILD A FIRE? Combustion reaction.
- 47. WHY IRON DECAYS WHEN IT IS KEPT OUTSIDE FOR A LONG TIME? Redox reaction
- 48. HOW SOAPS CLEAN DIRT? Soap emulsifies dirt. Detergents act assurfactants, lowering the surface tension of water. Interact with oils,isolate them, and rinse them away.
- 50. BAKING SODA WITH VINEGAR Double displacement reaction The CO2 forms bubbles in the volcanoes
- 51. WHY BUBBLES ARE LOST WHEN WE LEAVE A SODA CAN OPEN FOR A LONG TIME? Carbonic acid (the fizz) decompose into CO2 and H2O. Decomposition reaction
- 52. WHY WE CHERT IS APPLIED ON SKIN WHEN ANTS BITE? Ant leave formic acid (H-COOH) on our skin. It irritates our skin. Chert is a kind of base. it neutralizes formic acid So the irritation ends. Neutalisation reaction
- 53. WHY RAIN BECOMES ACIDIC?
- 54. CONCLUSION Chemistry is all around us, but the only thing is that we need to observe it carefully and notice everything around us. We should appreciate the work of scientists who observed those things and bought it to us.
