At which temperature and pressure will a sample of neon gas behave most like an ideal gas?

A)
300. K and 2.0 atm

B)
300. K and 4.0 atm

C)
500. K and 2.0 atm

D)
500. K and 4.0 atm

C. 500K and 2.0

Explanation:

Since real gases behave least ideally at low temperature and high pressure, they would behave most like an ideal gas at high temperature and low pressure.

the answer would be c

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.
