Answer:
a)[H+]=[OH-]= 1.708e-7
b)pH = 6.76
c)pH=13
Explanation:
a) Kw=[H+](OH-)=2.92e-14
As [H+]=[OH-]=take it equal to x
x2=2.92e-14
take squre root on both sides
we get x=1.708e-7=[H+]=[OH-]
b) As we know that pH = -log[H+]
putting the value in above equaton we get
pH= -log[1.708e-7]
pH = 6.76
c) if [OH-]=0.10 M FIND pH
pOH = - log(OH-)
pOH = - log(1e-1)
pOH = 1 but we also know that pH+pOH=14
sp pH=14-pOH
pH=14-1
pH=13
I'd be an outlet so that i'd never run out of energy and power like batteries and generators do cx
Yes , because when u breathe it in u get lyf and energy if u didn’t u would just die ( I’m doing this so I can ask a question myself so idk if this is even right)
Answer:
the answer you marked is correct
Explanation:
Answer:B
Explanation:
the particles in a gas are more far apart and have more kinetic energy than liquid because they are more close together and have less kinetic energy than gas.
