Use the following balanced chemical equation to answer the question that follows. Show work using dimensional analysis, units, and round answer according to correct sig figs 2 Cu, S(s) + 3 O2(g) 2 Cu2O(s) + 2 SO2(g)
If 125 grams of oxygen gas react according to the equation above, how many grams of copper(l) oxide are expected to be formed?​

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.

b. is the answer hoped i
