Answer:
Composition of the mixture:
%
%
Composition of the vapor mixture:
%
%
Explanation:
If the ideal solution model is assumed, and the vapor phase is modeled as an ideal gas, the vapor pressure of a binary mixture with
and
molar fractions can be calculated as:

Where
and
are the vapor pressures of the pure compounds. A substance boils when its vapor pressure is equal to the pressure under it is; so it boils when
. When the pressure is 0.60 atm, the vapor pressure has to be the same if the mixture is boiling, so:

With the same assumptions, the vapor mixture may obey to the equation:
, where P is the total pressure and y is the fraction in the vapor phase, so:
%
The fractions of B can be calculated according to the fact that the sum of the molar fractions is equal to 1.
Answer:
When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.
Explanation:
Answer:
The heat generated per gram of sample in calories is 0.87 g
Explanation:
Given that,
A calorimeter made from a can is used to measure the calories in a peanut.
During the experiment, the measured calories were 35% of the true/accepted value given by references
Suppose, the mass of peanut is 0.4 g and find the
We need to calculate the heat generated per gram of sample in calories
Using formula of heat generated

Put the value into the formula


Hence, The heat generated per gram of sample in calories is 0.87 g
