A gas has more free molecules, and it is air, not a tangible substance. Hope it helps! :)
Answer:
The correct answer to the following question will be "NaCl".
Explanation:
- A solute is being known as the soluble material within a liquid or a solution. The solvent is available in larger quantities than those of the solute among fluid.
- Concentration seems to be a calculation including its quantity of solvent contained in such a liquid solution, regard to something like the solvent volume.
So that NaCl is the right answer.
Explanation:
The nitrogen group is considered mixed because it is composed of elements of equally different classifications of metal, non-metal, and metalloids. The group contains the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metals bismuth (Bi) and Moscovium (Mc).
<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
