Answer:
Fossil fuels and biomass combustion.
Explanation:
The mass combustion of fossil fuels and biomass results in the vast release of Black Carbon (BC) and Brown Carbon (BrC) and dust. These Black Carbon, light absorbing organic Brown Carbon and dust cause the discolouring and yellowing of the surface of Taj Mahal building.
Average kinetic energy of the particles in the object
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
