Answer is: Kw of pure water at 50.0°C is <span>5.50 × 10-14</span><span>.
pH = 6.630.
pH = -log</span>[H⁺].
[H⁺] = 10∧(-pH).
[H⁺] = 10∧(-6.63) = 2.34·10⁻⁷ M.
[H⁺] · [OH⁻] = x.
Kw = ?.<span>
Kw = [H</span>⁺] · [OH⁻]. <span>
Kw = x².
Kw = (</span>2.34·10⁻⁷ M)².
Kw = 5.50·10⁻¹⁴ M².
Kw is ionic product of water.
Answer:
Input work is the work done on a machine as the input force acts through the input distance. This is in contrast to output work which is a force that is applied by the body or system to something else. Output work is the work done by a machine as the output force acts through the output distance.Jan 15, 2020hshs sbsh shs sshs sgsgd hd hd dud dud dhddbdydbdhd dhdh duddhdhdbdhbd
