In a heterogeneous equilibrium system the reactants and products exist in what?
Different physical states
In what system can reactants exist in the same physical states?
Heterogeneous Equilibrium
What happens to the equilibrium concentration of reactants when the volume of the reaction system is decreased and why?
decrease in reactants and increase in products
How is a battery different to a cell?
A fuel cell is different from a battery cell in so far as reactants are constantly supplied to a fuel cell making it an open system whereas a battery cell is a closed system that stores the reactants within it. A fuel cell works as long as fuel is supplied to it whereas a battery cell requires regular replacements.

How does reaction quotient predicts the direction of a reaction?
The reaction quotient is the ratio of products to reactants not at equilibrium. If the system is at equilibrium then Q becomes Keq the equilibrium constant. Q = products/reactants If Q < Keq then there are more reactants then products so the system must shift toward the products to achieve equilibrium. If Q > Keq then there are more products than reactants and the system must shift toward the reactants to reach equilibrium.
What is the law of conservation of change?
states that a particular measurable property of an isolated physical system does not change as the system evolves
Why is the SI system easy to use?
SI system is a rationalised MKS system.The earlier MKS system provided different units for different physical quantities, which was not at all convinient to use. But, the MKS system provides single unit for different physical quantities,which makes it convinient. The CGS system could not find solutions to physical quantities not involving LENGTH,TIME and MASS. Hence, it could not be used. The FPS system or BUS system was not a metric system and hence was not useful.
When no net change occurs in the amount of reactants and products a system is said to be in?
The system is in equilibrium.
Which body systems are involved in providing the reactants?
digestive system
What happens to the reactants that form products to the stability of the chemical system?
The chemical composition and structure of reactants are of course modified.
How can observing an experiment alter the outcome?
On the very small scale, i.e. quantum mechanics, a system is not in a specific state but there are different probabilities for the different states. By observing (measure) a physical property the system is forced into one of the possible states. The problem is that not all properties are mutually measurable, when one property is observed the other one is changed (because the first observation forces the system into one specific state).
