Explanation:
[H+]=10^-pH
[H+]=10^-9.2
[H+]=6.031x10^-10
[OH-]=1x10^-14÷[H+]
[OH-]=1x10^-14÷[6.031x10^-10]
[OH-]= 1.66x10^-5
im pretty sure this is right
I'm going to have to say A. My reason to that is because when you leave a cup of hot cocoa (assuming its hot), it gives off the heat (exothermic) the
Answer:
Difference between Homogeneous mixture and Heterogeneous Mixture are as follows:
- A mixture or sample that is consist of uniform composition and properties is called a homogeneous mixture while a mixture or sample that is consist of different composition and properties is called a heterogeneous mixture.
- Homogenous mixture has only single phase while heterogeneous mixture has two or more phases.
- Homogenous mixture can not be separated by physical methods while heterogeneous mixture can be separated out physically.
- Example of homogenous mixture is Water and sugar and heterogeneous mixture is oil and water.
