Asample of 02 gas occupies 346 ml at 45°c and 1.50 atm. what is the volume of this o2 gas sample at stp? enter your answer in the provided box. l l

Explanation:

The given data is as follows.

      = 346 mL,     = = (45 + 273) K = 318 K,

      = 1.50 atm,    = ?,   = 273 K,

      = 1 atm

And, according to ideal gas equation,

Now, putting the given values into the above formula and we will calculate the final volume as follows.

            = 445.56 mL

Thus, we can conclude that the volume of this gas sample at STP is 445.56 mL.

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.
