HEL 15 POINTS RIGHT HERE The Claus reactions, shown below, are used to generate elemental sulfur from hydrogen sulfide.

2H2S + 3O2 > 2SO2 +2H20

SO2 + 2H2S > 3S +2H2O

If 31.3 g of oxygen gas is consumed, how many grams of sulfur are produced?

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.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
