MULTIPLE CHOICE Question 18 Which scenario best describes the long-term health effect of air pollution exposure? A woman exposed to toxic chemicals in ground-level air pollution experiences a change in DNA, resulting in lung cancer. B. A man exposed to toxic chemicals in ground-level air pollution experiences extreme eye irritation that clouds his vision. A man exposed to toxic chemicals in ground-level air pollution experiences a cough. D. A woman exposed to toxic chemicals in ground-level air pollution experiences an ex- treme headache.

MULTIPLE CHOICE Question 3 Soil samples from a site show contamination by lead, lithium, and mercury. What is the most likely source of this pollution? A leaking batterles in a nearby landfill pesticide from a nearby residential neighborhood C. fertilizer from a nearby farm human sewage leaked from a nearby septic tank B.

i)16O and 18O are two different isotopes of oxygen. What is  ONE IS TRUE about 18O? it less easily evaporated than 16O it is more volatile and reactive than 16O it is lighter than 16O it is more commonly occurring than 16O II) Ice core samples taken from Antarctica have been used to estimate changes in surface temperatures and the atmospheric concentrations of carbon dioxide and methane. This data indicates that when the temperature is relatively warm, the amounts of carbon dioxide and methane are ___________ Select one: relatively low (negative correlation) sometimes high, sometimes low (no correlation) relatively high (positive correlation) III) The answer to the previous above question indicates that ___________ . Select one: high atmospheric concentrations of carbon dioxide and methane might lead to warmer temperatures high atmospheric concentrations of carbon dioxide and methane might lead to cooler temperatures there is no…

Please do Question 2

Describe why ozone is more reactive than oxygen gas?

Direction: Classify each example below. Write C, if it is chemical, M, if it is mechanical, and B, if it is Biological Weathering. 1.) A seed has found its way into a rock and a plant is beginning to split the small stone. 2.) The pollution has recently been high, and acid rain is destroying some monuments. 3.) A combination of fungi and algae grow upon the surface of a rock slowly "eating it away". 4.) Flooding has caused a landslide and part of the hillside has been affected. 5.) The salty water of the ocean is eating away the concrete support posts of the pier.

Possible death for animals and human being is expected for 430 ppm of chlorine gas exposure in 30 minutes. Cl2 released from MGPI approximately 45 minutes. Determine the probable death percentage from this toxic release accident.

1. What compounds are in the following? Sodium bicarbonate Baking powder Baker's ammonia 2. What is the purpose of the Gas Pressure Sensor for our measurements? 3. What is the purpose of using baking soda or baking powder? 4. Simona set up an experiment to measure the volume of 5.0 g of CO2 gas given off during a reaction at 298 K. She measures the pressure to be 5 kPa. What is the volume of gas?

- What chemical species in the atmosphere acts like nature’s cleaning agent? Give the symbol and name. -What is one physical mechanism (i.e., not a chemical reaction) through which trace gases can be removed from the atmosphere?
