Answer:
The particles that compose a gas are so small compared to the distances between them that the volume of the individual particles can be assumed to be negligible.
Explanation:
This is a postulate of the Kinetic Molecular Theory.
A is wrong. KMT assumes the that the volume of the particles is negligible.
B is wrong. KMT assumes that the distance between the particles is muck greater than their size.
D is wrong. It takes the large distances as a fact. KMT uses this as an assumption.

In an acid-base titration, the neutralization reaction between the acid and base can be measured with either a color indicator or a pH meter. In this experiment, aphenolphthalein<span> color indicator will be </span>used<span>.
</span>Phenolphthalein<span> is colorless in acidic solutions and pink in basic solutions.

Answer: The initial partial pressures of
and
is 139.4 torr.
Explanation:
The equilibrium reaction is

initially conc. p p 0
At eqm. p-2x p-x 2x
Given: 

The expression for equilibrium constant is :

= 2x =115 torr
= (p-2x) = p-115 torr
= (p-x)= p-57.5 torr
Now put all the given values in this expression, we get


Therefore, the initial partial pressures of
and
is 139.4 torr.
