A mixture of 0. 10 mol of NO, 0. 050 mol of H2, and 0. 10 mol of H2O is placed in a 1. 0-L vessel at 300 K. The following equilibrium is established: At equilibrium (a) Calculate the equilibrium concentrations of H2, N2, and H2O. (b) Calculate Kc.

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.
