Kw = [H+][OH-] [H+] = 10-pH = 10-6.17 For [OH-] remember that heat causes more water molecules to self-dissociate but for every new H+ generated, a OH- is generated as well. Therefore, the concentration of H+ and OH- is equal. [OH-] = 10-6.17 Kw = [H+][OH-] = 10-6.17 * 10-6.17 = 10-12.34
"The pH of PURE water will always be 7."
This is false. As the temperature rises for pure water, so does the Kw value. Kw=2.917 x 10^-14.
Kw=[OH-][H+].
Kw=[1.708 x 10^-7]^2.
-log(1.708 x 10^-7)=6.76=pH
At normal pressure steam changes to liquid water at 212 degree F.
Moles Cl2 = 25g x 1mol/71g 0.35 molesPV =nRT and T = PV/nR T = (1.5)(6)/(0.35)(.0821) T = 313 deg K = 40.2 deg C to 3 sig figs
Approx 3.29 moles.
He started in England. He went aboard HMS Beagle for five years. During that time,he visited Tenerife, the Cape Verde Islands, the Brazilian coast, Argentina, Uruguay, Tierra del Fuego, Chile, the Galapagos Archipelago, Tahiti, New Zealand, Tasmania and the Keeling Islands
The formula is:U = cNT ,where- U - the internal energy- c - heat capacity of the gas- N - number of moles- T - absolute temperatureSo, U = 29,124 x 7 x 313 = 63 810,7 J.

313 Kelvin.
PV/T=Constant Providing the volume remains constant. P/T=C 35/313=20/T Therefore T=178.9Kelvin
1 and 313 (313 is a prime number).
313 is a prime so radical 313 cannot be simplified.
97969
It is: 334 -313 = 21
x x 313 = (x)(313) = 313x
There are no units for the temperature. The temperature change could be 230 Celsius degrees or 170 Fahrenheit degrees (94 Celsius degrees). In fact they could be in less commonly used units: eg Reaumur.
127
The answer should be 2x-313
313 + 406 = 719
