AIR POLLUTION Air pollution is the introduction of chemicals‚ particulate matter‚ or biological materials that cause harm or discomfort to humans or other living organisms‚ or cause damage to the natural environment or built environment‚ into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth’s ecosystems

QUESTIONS 1) The control in this experiment was the bag that contained the radish seeds with tap water. This was an important part to have in the experimental design because I was able to compare this to the other bags that contained coffee‚ ammonia‚ and vinegar. With the results that I collected‚ I was able to gather more observation and data. 2) The independent variable in this experiment was the pH level of the solutions‚ whereas the dependent variable was number of seeds that each solution

there is a horrid smell coming from the ammonia cleaner he is using‚ which is making me feel quizzical about how the window spray can be so smelly – I don’t understand! I feel embarrassed because I misspelled “bizarre” on our Bizarre Elementary centennial banner. Everything is going wrong! Our mascot’s new Barracuda costume (Go‚ Barracudas!) came in a cellophane wrapper. Our mascot is allergic to cellophane‚ so he threw up inside the costume‚ and now the ammonia scent and the barf scent combined and

hypothesis was that if bleach was used‚ it would be the most effective because bleach is commonly used to clean and disinfect various things. The variables that were tested were antibacterial soap and Scope mouthwash for the antiseptics; bleach and ammonia for the disinfectant; and Cipro‚ erythromycin‚ and tetracycline for the antibiotics. All of these chemicals were used on the bacteria M. luteus. Two Petri dishes were covered in the bacteria and split into four quadrants‚ in which each had a disc

1. Aim: To determine the weight-to-volume percent of acetic acid present in commercial vinegar and the weight-to-volume percent of ammonia present in window cleaners. Acid-base titrations can be conducted using the above samples against standardized aqueous NaOH and standardized aqueous HCl solutions respectively. 2. Introduction: Acetic acid‚ commonly known as ethanoic acid CH3COOH‚ is found in commercial vinegar. It is a weak organic acid that gives vinegar its characteristic pungent smell‚
