At a certain temperature the vapor pressure of pure chloroform CHCl3 is measured to be 415.torr. Suppose a solution is prepared by mixing 149.g of chloroform and 110.g of acetyl bromide CH3COBr.

Calculate the partial pressure of chloroform vapor above this solution. Be sure your answer has the correct number of significant digits.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

the answer is minerals.
