A sample of an ideal gas has a volume of 3.15 L at 13.20 Celcius and 1.90 atm. What is the volume of the gas at 18.00 Celcius and 0.990 atm?

Thanks:)

The ideal gas law is PV= nRT.

First you need to manipulate the equation to splice for volume,

Which will be V= nRT/P

Now you need to input the numbers for each variable. Make sure to remember what the value R equals and it’s units. R= 0.08206 L•atm/n•K

Explanation:

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )

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.
