Answer:
I'm not sure that is the full question can you show a picture or something?
Answer:
Physical Properties:
- The grass is green.
- The wood on the house is brown.
- The house is solid.
- The stone on the house is dark grey.
- The trees are green.
- The glass in the windows is clear and colourless.
Chemical Properties:
- The wood is flammable.
- The stone is not flammable.
Explanation:
Physical properties are properties that don't require a chemical reaction to be measured, for example the colour. Chemical properties are properties that are observed when a substance undergoes a chemical reaction, for example flammability.
When the reaction N₂ + 3 H₂ ⇌ 2 NH₃ is at dynamic equilibrium, Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
The reaction is at dynamic equilibrium.
N₂ + 3 H₂ ⇌ 2 NH₃
Which statement is correct?
- The solution has the same concentrations of nitrogen gas and ammonia. NO. Even though we don't know the equilibrium constant, it is unlikely that N₂ and NH₃ have the same concentrations at equilibrium.
-
Nitrogen and hydrogen combine at the same rate that ammonia breaks down. YES. At the equilibrium, the forward rate is equal to the reverse rate.
-
The solution has the same concentrations of nitrogen and hydrogen gases. NO. Even though we don't know the equilibrium constant, it is unlikely that N₂ and H₂ have the same concentrations at equilibrium.
-
Both directions of the reaction have stopped. NO. The reactions don't stop because the equilibrium is dynamic.
