Answer:
Explanation:
The formation of ammonia that occurred by the reaction of nitrogen and ammonia is expressed as:
⇄ ![2NH_{3(g)}](https://tex.z-dn.net/?f=2NH_%7B3%28g%29%7D)
where;
The reactants are:
Hydrogen and nitrogen
The product is ammonia.
For the reaction, the equilibrium constant can be expressed as:
![K = \dfrac{[product]}{[reactants]}](https://tex.z-dn.net/?f=K%20%3D%20%5Cdfrac%7B%5Bproduct%5D%7D%7B%5Breactants%5D%7D)
![K = \dfrac{[NH_3]^2}{[N_2]^3[H_2]^3}](https://tex.z-dn.net/?f=K%20%3D%20%5Cdfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5E3%5BH_2%5D%5E3%7D)
From the equilibrium constant conditions, the formation of ammonia and its decomposition due to its reversible reaction back to hydrogen and nitrogen are equal. It implies that the rate of the forward reaction is also equal to that of the backward reaction.
Thus, during when equilibrium is obtained;
Hydrogen, Nitrogen, and Ammonia are present.
Answer:
See below.
Explanation:
I'll do the second row for you the other 2 are done in exactly te same way.
B. Area of 1 side of cube = 2*2 = 4.
Surface area = 4*6 = 24
Volume = 2*2*2 = 8.
Surface area / volume = 24/8 = 3.
Ratio of Suface Area to Volume = 24 : 8 = 3 : 1. (divide both by 8)
Answer:
cylinder A has a higher density then cylinder B or more accurately the liquid in cylinder A is denser then the liquid in the second tube.
Explanation:
"Denser" simply means more matter is contained in the same space for example say you fill a tank with helium and another tank with water. Although they are the same size one will weigh much more because their is more particles or "stuff" inside the same area this can be because of a few things one it can be because the atoms or elements that compose the substance are heavier containing more electrons and protons in their orbit. or the molecular structure is more compact like a chicken wire fence has more wire in it then a barbed wire wire fence covering the same area because of the grid of wire in the middle.
I can’t see it can you write the problem ?
