Answer:
A) increasing tension in the vibrating object.
Explanation:
The given data is as follows.
= 0.483, = 0.173 M,
= 0.433 M, = 0.306 M,
= 9.0 atm
According to the ideal gas equation, PV = nRT
or, P =
Also, we know that
Density =
So, P = MRT
and, M =
=
=
= 0.368 mol/L
Now, we will calculate the cell potential as follows.
E =
=
=
=
= 0.483 - 0.0185
= 0.4645 V
Thus, we can conclude that the cell potential of given cell at is 0.4645 V.
Out of
the following given choices;
A. increasing
the pH of the salt.
B. increasing
the surface area of the salt.
C. increasing
the pressure of the salt.
<span>D. increasing
the temperature of the salt.</span>
The answer is B. When a substance is reduced to smaller
sizes, its surface area to volume ratio increases. Therefore crushing barium
salts to smaller particles increase the surface area on which it reacts with
the acid. This consequently increases the rate of speed of the reaction.
The answer to this is B, solids with a repeating atomic pattern.
