As,
Water has a pkw=14
so it can be represented as,
[H+] [OH-] = 1*10^-14
If [H+] = 3*10^-5M
[OH-] = (1*10^-14) / ( 3*10^-5)
[OH-] = 3.3*10^-9 M
Answer:
Sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet.
Explanation:
Phosphorus pentachloride (PCl5) and sulfur hexafluoride (SF6) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom
The pH of a solution depicts the alkalinity or the acidity of the components of the solution and is given as a negative log function of hydrogen ions.
The pH of the solution is:
2
The pH can be estimated as:
- Ionic equation of reaction is written as:
- The mole ratio between HCl and = 1 : 1
- Concentration of = 0.01 M
Therefore, 2 is the pH of the solution.

I believe that your option C would be the correct answer. We know that water can turn to a solid materail because during cold temperatures, water turns to ice.
We know that water can turn to gas, as water can evaporate.
And also, we know that water is obviosly a liquid.
Therefore, Option C would be your answer.
<span>If heat is consumed during a reaction, the reaction is said to be an endothermic reaction.
There are two types of reactions related to heat energy, these are endothermic and exothermic </span>reactions.
Exothermic reactions are when the reactions as it proceeds gives out heat energy to the surroundings. Endothermic reactions are when heat energy is absorbed by the reactants to initiate and continue the reaction. Therefore reaction system absorbs or consumes heat energy from the surrounding.
