The net extra energy released in this reaction can then go on to rip more carbon atoms free of their non-oxygen neighbors, thus continuing the reaction, or the energy can escape as heat and ligh

On what basis can mixtures be classified as solutions suspensions or colloids
FinnZ [79.3K]

Answer:

A mixture is classified as a solution when there is an homogeneous mixture of the two or more substances involved in a given medium.

A mixture is classified as a suspension when there is a heterogeneous mixture of undissolved particles in a given medium.

A mixture is classified as a colloid (false solution) when the individual solute Particles are larger than the particles of true solution, but they are not large enough to be seen by the naked eye. The solutes can scatter light rays.
