The vapor pressure of liquid diethyl ether, C2H5OC2H5, is 40.0 mm Hg at 245 K. A sample of C2H5OC2H5 is placed in a closed, evacuated container of constant volume at a temperature of 383 K. It is found that all of the C2H5OC2H5 is in the vapor phase and that the pressure is 49.0 mm Hg. If the temperature in the container is reduced to 245 K, which of
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
The vapor pressure of liquid diethyl ether, C2H5OC2H5, is 40.0 mm Hg at 245 K.
A sample of C2H5OC2H5 is placed in a closed, evacuated container of constant volume at a temperature of 383 K. It is found that all of the C2H5OC2H5 is in the vapor phase and that the pressure is 49.0 mm Hg. If the temperature in the container is reduced to 245 K, which of the following statements are correct?
Choose all that apply.
Some of the vapor initially present will condense.
No condensation will occur.
Liquid diethyl ether will be present.
The pressure in the container will be 40.0 mm Hg.
Only diethyl ether vapor will be present.
