Hello There! ^_^
Your question: What is the pressure of a fixed volume of hydrogen gas at 38.8°C if it has a pressure of 1.36 atm at 15.0°C..?
Your answer: P1/ T1= P2/ T2
Change C to Kelvin
273+ C= K
38.3+ 273= 311K
15.0+ 273= 288K
2.38/ 288= P2/ 311.3
740.894= 288 (P2)
P2= 2.57 atm.
Thus, you got you answer!
Hope this helps!
[H+][OH-]=10-¹⁴
We are using this formula because we need to find the H+
substitute the value given for hydronium ion for OH-
[H+][4.19×10⁵]=10-¹⁴
[H+]=10-¹⁴÷4.19×10⁵
[H+]=2.387×10-¹⁹
Then the pH of the solution will be
pH= –log¹⁰ [H+]
pH = –log¹⁰ [2.387×10-¹⁹]
pH= –log¹⁰2.387+19log¹⁰
= –0.378+19
pH =18.622
Answer:
C
Explanation:
It is most likely non metal with a high electronegativity.
