Explanation:
The of an acid = -5.7
The dissociation constant of the reaction =
The relation between and is given by ;
The value of dissociation constant of an acid .
I'm pretty sure it's C.
A gas can be compressed, but I'm not sure that it actually takes the shape.
Answer:
It is 27 % guanine.
Explanation:
They also know that cytosine always pairs off with guanine.
If the molecule is 27 % cytosine, it must also be 27 % guanine.
Gravity
Explanation:
The unpowered cars as shown gets their potential energy from their acceleration due to gravity and the height above the ground of the hill.
Potential energy is the energy due the position or a body. It is energy primarily at rest of a body.
Potential energy = m x g x h
Where:
m = mass
g = acceleration due to gravity
h = height of the hill.

We know that the element Z = 119 would be placed right below the Fr, in the column of the alcaline metals.
We also know that the trend in the electronegativity is to decrease when you go up-down ia group.
The known electronegativities of the elements of this group are:
Li: 0.98
Na: 0.93
K: 0.82
Rb: 0.82
Cs: 0.79
Fr: 0.70
Then the hypotetical element Z = 119 would probably have an electronegativity slightly below 0.70, for sure in the range 0.60 - 0.70.
