The pH of a solution that has a H⁺ ion concentration is 0.0039M is 2.4.
<h3>What is pH?</h3>
pH of any solution gives idea about the acidity or basicity of solution and it will be calculated as:
pH = -log[H⁺]
Given that, concentration of H⁺ ion = 0.0039 M
On putting tis value in pH equation, we get
pH = -log(0.0039)
pH = -(-2.4) = 2.4
Hence required value of pH is 2.4.

Answer:
Energy added to solid water will turn it into liquid water; add energy into liquid water and it will be turned into water vapor.
Explanation:
Adding energy is basically adding heat; the more heat, the more excited the molecules of H2O gets. In solid water, the molecules aren't really moving because they don't have a lot of energy, so it is solid. In liquid water (which is water in room temperature), it has a medium amount of energy; the molecules aren't stuck together but it isn't completely dispersed, so it is in liquid form. However, in water vapor, the energy becomes very high and the molecules are excited. The hydrogen bonds holding the molecules together break and the water is released as a vapor.
Answer:
the correct answer is c
Explanation:
becuase i had the same question
n=m/M
8.0g÷58.10g/mol=0.14mol
V=n/c
0.14mol÷0.89M=0.16L=1.6×10²mL
