Sarah is asked the following question: the volume of a gas collected when the temperature is 11.0C and the pressure is 710 mm Hg measures 14.8
mL. To find the number of moles of gas are present, what equation does
Sarah need to use?

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

11 players on a field that has a maximum of 11 players

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
