Chapter 2, Problem 34Q
Here are air quality data for the last week of 2015, in Beijing, China, for air quality based on the primary pollutant of PM2.5.
- a. In general, which groups of people are the most sensitive to particulate matter?
- b. The U.S. Environmental Protection Agency determined that air rated between 51–100 is acceptable except for particularly sensitive groups. For the data shown, when was the air acceptable or better?
- c. The levels of PM do not necessarily drop off at night the way they do for ozone. Explain.
- d. The levels of particulate matter can increase sharply. Propose two different reasons that could account for this observation.

Some greenhouse gases, such as fluorocarbons (CFCs, HFCs, PFCs, etc.), are human-made. Others, such as water, methane, and carbon dioxide, are naturally produced. Which type of greenhouse gas (human-made or natural) is more difficult to control and eliminate? Which types are easier? In three to five sentences, provide evidence for your argument.
A student dissolves 10.3g of ammonium nitrate NH4NO3 in 300.g of water in a well-insulated open cup. He then observes the temperature of the water fall from 22.0°C to 19.3°C over the course of 3.1 minutes.
Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction:
NH4NO3s -> NH+4aq + NO−3aq
You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to the correct number of significant digits.
Is this reaction exothermic, endothermic, or neither?
If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in this case.
Calculate the reaction enthalpy ΔHrxn per mole of NH4NO3.

- Marie Curie was born in Poland but studied and carried out her research in Paris. In 1903, she shared the Nobel Prize in Physics with H. Becquerel and her husband Pierre for their discovery of radioactivity. (In 1911 she received the Nobel Prize in Chemistry for the discovery of two new chemical elements, radium and polonium, the latter named for her homeland, Poland.) They and others observed that a radioactive substance could emit three types of radiation: alpha (), beta (), and gamma (). If the radiation from a radioactive source is passed between electrically charged plates, some particles are attached to the positive plate, some to the negative plate, and others feel no attraction. Which particles are positively charged, which are negatively charged, and which have no charge? Of the two charged particles, which has the most mass? Radioactivity. Alpha (), beta I(), and gamma () rays from a radioactive element are separated by passing them between electrically charged plates.arrow_forwardGreenwashing is a major problem. Companies will say they are using practices that benefit the environment while really not taking any steps to do so.
