<span>This problem uses the relationship between Ka and the concentrations of the ions. Calculations are as follows:</span>

<span>
</span><span>1.9 x 10-5</span>= x^2 / (0.25 - x)

<span>x is very small and the denominator is approximately equal to 0.25. Thus, x is 2.2 x 10^-3

</span><span>pH = -log (2.2 x 10^-3)</span> = 2.66

Substances that make up a mixture __________ their own properties once they are combined to form a mixture. Please help. I need
Stels [109]
I believe the answer to this is;
Substances that make up a mixture RETAIN their own properties once  they are combined to form a mixture. 
    I believe the answer is RETAIN because the combination in question is a MIXTURE. A mixture is a combination of various substances. In the case of mixtures, all the substances retain their own properties. That is; they remain the way they are and do not change. An example of a mixture is air. And to prove that air is a mixture;
The components of air retain their individual properties.
The components of air cannot be represented by a chemical formula
When the components of air combine, they do not show any form of chemical change, like heat release, change in pressure.....
  Hope i helped, have a nice day.
