Study the graph about the negative effects of indoor air pollution. A pie graph titled Indoor Air Pollution-Caused Deaths and Breakdown by Disease. Diseases listed by greatest to least common: Stroke, Ischemic heart disease, C O P D, Acute lower respiratory infections in children, Lung cancer.

What does the graph show about the importance of clean air?

People have a lower risk of dying from COPD when compared to acute lower respiratory infections.
The health risk is the highest for getting lung cancer when people are exposed to indoor air pollution.
Most people will die from the negative health effects associated with stroke as indoor dirty air builds up.
The risk of developing acute lower respiratory infection and ischemic heart disease is the same when exposed to indoor air pollution.

150.0 grams of asf3 were reacted with 180.0 g of ccl4 to produce ascl3 and ccl2f2. if the actual yield of ccl2f2 was 127 g, what is the percent yield?

1. calculate the approximate enthalpy of the reaction in joules. estimate that 1.0 ml of vinegar has the same thermal mass as 1.0 ml of water. iqnore the thermal mass of th sodium bicarbonate. note: it takes about 4.2 joules () to change 1.0 gram (1.0ml) of water 1.0 c

Achemical reaction (also known as a chemical change) produces substances that are chemically different from the starting materials. an example of a chemical reaction is the formation of water from hydrogen and oxygen gas.in a physical change, a substance changes its physical appearance but not its chemical identity. an example of physical change is the formation of liquid water from solid water, a familiar process called melting. physically, liquid water looks very different from solid water (ice) but the chemical identity, water, is the same for both. which of following changes that affect the composition of our atmosphere involve physical changes and which involve chemical reactions? oxygen gas changes to ozone during thunderstorms carbon dioxide is produced by the combustion of gasoline in an automobile engine. when coal, oil, and natural gas are decomposed in landsills they produce methane gas. freezing rain develops when a warm air mass overrides a cold air mass. fog forms from water vapor when the temperature drops below the dew point
