<span>pH + pOH = 14
</span><span>What is the pH of a solution if its pOH is 12.4?
pH = 14 - 12.4
pH = 1.6</span>
You’ve not put anything below so I’m not sure what the options are but the relative charge of a proton is +1
Transparent is completely clear, like a clean window.
Translucent is like a really dirty window, because it still allows light in, but you cant really see through it.
I hope this helps! :)
I believe the correct answer from the choices listed above is option A. The topic that the teacher is talking about would be distillation of a mixture. Gasoline is processed by distillation. Hope this answers the question. Have a nice day.
Answer:
(4) concentrated and supersaturated
Explanation:
At 50.°C, 90g of KNO3 lies above the solubility curve [on the Regents Reference Table G]. This indicates that the solution is supersaturated, meaning it contains more solute than will naturally dissolve, and was formed when a saturated solution cooled. Furthermore, the percent concentration of this solution is 90% KNO3 making this solution concentrated. This can be calculated using the formula for mass percent concentration.
Percent Mass = <u>Mass of Solute (g)</u> x 100
Mass of Solution (g)
