The correct answer is <span>A. The transfer of heat and energy
Sound waves, electron movement, and conservation of matter are studied by different parts of physics. Thermo is an ancient root word/prefix that is used to refer to heat. An example of that is a Thermos, which is supposed to save heat of a liquid.</span>
Explanation:
The dissociation constant of the water is given as :
The value of st 25°C =
Water is neutral in nature with equal amount of hydronium and hydroxide ions.
The pH of the water at 25°C is 7.
With increase in temperature dissociation of water will increase with which concentration of hydronium and hydroxide ions will also increase which will in return will lower the down the pH of the water at higher temperature.
Okay so we know that pOH + pH = 14, so if pOH is 0.253 the pH would be 13.747.
<span>And pH = -log [H+], so [H+] = 10^(-pH) -->This is just the antillog... </span>
<span>so [H+] = 1.791e-14, which would make sense for the strongly basic solution (so B is the correct answer) </span>
<span>Hope this helps...</span>
<span>magnesium oxide is a compound that is composed of one atom of magnesium and two atoms of oxygen. The compound is a combination of Mg2+ ion and O2-. The ions translate into atoms which reflects on the subscripst of the elements already. magnesium oxide is a basic oxide with the pH level greater than 7.</span>
