Asample of gas occupies 555ml at 175 cm hg and a temperature of 37.0c. what is the new volume (in ml) at stp?

The new volume at STP is 1125.43 mL.

Explanation:

STP conditions:

Pressure of the gas is 760 mmHg and temperature of the gas is 273 K

To calculate the volume when temperature and pressure are changed, we use the equation given by combined gas law. The equation follows:

where,

are the initial pressure, volume and temperature of the gas

are the final pressure, volume and temperature of the gas

We are given:

Conversion factor:  1 cm = 10 mm

Putting values in above equation, we get:

Hence, the new volume at STP is 1125.43 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.
