A sealed reaction vessel initially contains 1.217×10-2 moles of water vapor and 1.490×10-2 moles of CO(g).

H2O(g)+CO(g)<>H2(g)+CO2(g)

After the above reaction has come to equilibrium, the vessel contains 8.733×10-3 moles of CO2(g). What is the value of the equilibrium constant Kc of the reaction at the temperature of the vessel?

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.

it's all four options.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
