Answer:
presence of vegetation or animal material
Density is defined as " the ratio of mass of the substance to its volume ". i.e.
d = m/v ------------------------ (1)
volume of the steel sample is required, so putting mass of the steel sample and its density in equation (1),
8 = 80 / v
It implies that,
v = 80 / 8
v = 10 cm^3
The answer is temperature!
Answer : The value of the equilibrium constant is,
Explanation :
The given main reaction is:
The intermediate reactions are:
;
;
;
Now we are adding all the equation, we get:
...........(1)
The equilibrium constant expression will be:
Now we are dividing equation 1 by 2, we get:
...........(1)
The equilibrium constant expression will be:
Now put all the given values in this expression, we get:
Thus, the value of the equilibrium constant is,
H2 has the lowest boiling point.
