6. At standard temperature and pressure 1 mole of any gas has a volume of 22.4 liters of gas. If the 5 grams of baking soda reacted at standard temperature and pressure, what volume of gas would be produced?

Stoichiometric Calculations Involving Ideal Gases at STP

Stoichiometric calculations involving gases allow us to convert between mass, number of moles, and most importantly, volume of gases. The following relationship makes this possible:

1 mole of any gas at standard temperature and pressure (273 K and 1 atm) occupies a volume of 22.4 L.

While the above relationship is an estimation, it is a relatively good approximation at STP, and can be used reliably in calculations.

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.
