Answer;
-Macroscopic properties remain constant
-Concentrations remain constant
-No change to copper solution seen;
-Rate of reverse/backwards reaction = rate of forward reaction;
Explanation;
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.
-It is a a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs. A reversible chemical reaction is one in which the products, as soon as they are formed, react to produce the original reactants.
Answer:
here is definition with example
Answer:
Warm or hot air particles have more energy than that of cool air. As a result they move faster than cool air particles. Since sound propogation involves movement or vibration of particles, sound travels faster in warm air
Hope this helps!
PH + pOH = 14
pH = 14 - pOH = 14 - 2 = 12
A pOH of 2 is equivalent to a pH of 12. A pH greater than 7 is basic, and 12 is greater than 7. Therefore, a solution with a pOH of 2 is basic.
Thus, the correct answer choice is B.
