Afuel gas containing 80% by mole ch4 and 20% by mol c2h6 is burned with dry air. sixty percent of the carbon burned goes to co2, the rest goes to co. fifty percent excess air is used. calculate the number of moles of each constituent of the wet flue gas produced by combustion of 100 moles of fuel gas, and also the orsat analysis of the flue gas.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

bcde is the incorrect answer it is a
