The activity of pure substance is taken as 1 because it has no effect on the reaction. Hence the equilibrium constant of the reaction is given by: <span>Ka=[H3O+][HCO1−3]/[H2CO3]. Hope this helps :)</span>
The answer is option C.
That is it is a heterogeneous mixture.
Heterogeneous mixture have the following properties:
1. Different components could be observed in the substance.
2. Different samples of the substance appeared to have different proportions of the components.
3.The components could be easily separated using filters and sorting.
When red litmus turns blue, means the solution is basic, so it has more OH⁻ (hydroxide) ions.
•common trends and similarities
•similar ions going down (ex: Mg+2 and Ca+2)
•same number of electron orbitals going across
The volume of the container will decrease. I believe this answer is correct because for the temperature and pressure to remain the same but there to be less particles the container must shrink to suit.
