The pH of a solution at 25. 0 °C that contains 2. 95 × 10^-12 m hydronium ions is 13.5.
<h3>What is pH? </h3>
pH is defined as the concentration of the hydrogen bond which is released or gained by the species in the solution which depicts the acidity and basicity of the solution.
<h3>What is pOH? </h3>
pOH is defined as the concentration of the hydronium ion present in solution.
pOH value is inversely proportional to the value of pH.
pH value increases, pOH value decreases and vice versa.
Given,
Total H+ ions = 2.95 ×10^(-12)M
<h3>Calculation of pH</h3>
pH = -log[H+]
By substituting the value of H+ ion in given equation
= log(2.95× 10^(-12) )
= 13.5
Thus we find that the pH of a solution at 25. 0 °C that contains 2. 95 × 10^-12 m hydronium ions is 13.5.

<h3>What is colligative property?</h3>
- Colligative properties in chemistry are those of a solution that depend on the amount of solute particles to solvent particles in a solution rather than the makeup of the individual particles.
- The number ratio can be connected to the several units used to measure a solution's concentration, including molarity, molality, normalcy (chemistry), etc.
- For ideal solutions, which are ones that have thermodynamic properties similar to those of an ideal gas, and for diluted actual solutions, the assumption that solution properties are independent of the type of solute particles is exact.
<h3>What factors affect colligative properties?</h3>
- A property of a solution is said to be collative if it depends simply on the proportion of solute to solvent particles in the solution and not on the nature of the solute.

What age group typically uses inhalants? I hope that’s a good one
Answer:
1
Explanation:
An unknown element, X, is a nonmetal that contains seven valence electrons. Element X most likely forms <u>1 </u>covalent bond.
Nonmetals gain the electron to complete the octet and form anion. Consider the example of halogen.
When it combine with another halogen atom they form covalent bond. There are seven valance electrons in outer most orbital of halogen atom. By combining with other halogen atom they form one covalent bond and complete the octet.
For example:
Cl atom combine with other Cl atom and form Cl₂.
