The [H₃0⁺] of the solution : 1.778 x 10⁻¹² M
<h3>Further explanation </h3>
pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.
A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.
pH of solution = 11.75
the [H₃0⁺] of the solution :
![\tt pH=-log[H_3O^+]\\\\11.75=-log[H_3O^+]\\\\(H_3O^+]=10^{-11.75}=1.778\times 10^{-12}](https://tex.z-dn.net/?f=%5Ctt%20pH%3D-log%5BH_3O%5E%2B%5D%5C%5C%5C%5C11.75%3D-log%5BH_3O%5E%2B%5D%5C%5C%5C%5C%28H_3O%5E%2B%5D%3D10%5E%7B-11.75%7D%3D1.778%5Ctimes%2010%5E%7B-12%7D)
Answer:
Alcohol has greater value of temperature coefficient of expansion than mercury.
<em><u>Answer:</u></em>
The Beaufort scale measures wind speed.
<em><u>Explanation:</u></em>
One way to measure wind speed is by observing its effects on objects. In 1805, a British naval officer named Sir Francis Beaufort developed a wind speed scale that refers to the movement of objects. The Beaufort Scale is a good way to introduce your students to the concept of wind speed.
Answer:
Carbon-carbon bonds. (Ans.A).
Explanation:
None covalent bonds are different from covalent bonds, they are not formed by the sharing of electrons which is present between the bonded atoms. They are formed by the help of electrostatic attraction or some other type of interaction found between the ions or atoms.
A carbon-carbon bond is known as a covalent bond, and they are formed with the help of the sharing of electrons which is found between the two carbon atoms. Both carbon atoms have 4 electrons for bonding.
Answer:
-a nonmetal is a substance that lacks the characteristics of a metal.
-Seventeen elements are generally classified as nonmetals: most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).
