coal Flashcards
stages of coal formation
Co2 is buried as org material and is compressed.
forms as peat>lignite>bituminous> anthracite
combustion of methane rxn
CH4 + 2O2 -> CO2 +2H2O
exothermic
combustion of propane rxn
C3H8 +5O2 -> 3CO2 +4 H2O
exothermic
what are the products of coal combustion
Co2 and H2O
per every 12g of C burned, 44g of CO2 are made
how does carbon monoxide form?
from incomplete combustion due to a lack of O2 in the given area (O2 is required for full combustion). without proper ventilation poisonous gas is formed.
CO replaces O2 in hemoglobin and causes suffocation
how much energy does china make from coal? wind? solar?
coal=2/3
wind=3%
solar2%
who is impacted by As poisoning from coal? why?
rural china areas that need to revert to coal for energy. In these areas, the coal has high lvls of As and they roast their peppers of the coals which are releasing the contaminants
who is impacted by F poisioning from coal? why?
rural china areas that need to revert to coal for energy. In these areas, the coal has high lvls of F and they roast their peppers of the coals which are releasing the contaminants
note coal contains high lvl of As, F, Hg, and thanllim in these areas
where is the largest coal deposit in china
datong city, shanxi
how much CO2 does china emmit
at least 1/5
what are environmental concerns in china overshadowed by?
jobs and income made by the coal industry
what toxci minerals are found in the coal of rural areas
As, F, Hg, and thallium
how manu people are affected by As poisoning in china
3000 ppl in Guizhou province
what are the symptoms of As poisoning
hyperpigmentation
black skin lesions
cancer
this arises bc the coal here has 35000ppm As when the average in US has 22ppm
how many ppl are affected by Florine positioning in china
more than 10 mill in Guizhou province
