Answer:
A. Warning
Explanation:
Out of all said choices, the best choice would be warning since it would fit the sentence the most.
"A Warning notifies you that danger is present." compared to:
"A Hazard notifies you that danger is present."
"A Safety notifies you that danger is present."
"A Danger notifies you that danger is present."
Assuming ideal gas law applies to the problem, we find the pressure from the given volume, temperature and number of moles. The ideal gas equation is PV=nRT. R is 0.0821 L atm/ mol K. Substituting the data given, P= (2.50 moles)(0.0821 L atm/ mol K)(27+273 K)/(50 L)= 1.2315 atm. This is equivalent to 936 mm Hg.
The H3O in a solution is 12.57.
<u>Explanation</u>:
The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH.
pOH = -log[H3O]
pOH = -log(3.75x10^-2)
= 1.43
Now, pH = 14 - 1.43
= 12.57
The H3O in a solution is 12.57.
