You will begin by diluting 5.00 mL of a 0.8 M oxalic acid stock solution with water to a final volume of 100.00 mL. What will be the final concentration of the oxalic acid

0.04M

Explanation:

The following were obtained from the question:

C1 = 0.8M

V1 = 5mL

V2 = 100mL

C2 =?

The final concentration of the diluted solution can be obtained by doing the following:

C1V1 = C2V2

0.8 x 5 = C2 x 100

Divide both side by 100

C2 = (0.8 x 5) /100

C2 = 0.04M

The concentration of the diluted solution is 0.04M

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.
