Answer:
K = 3.37
Explanation:
2 NH₃(g) → N₂(g) + 3H₂(g)
Initially we have 4 mol of ammonia, and in equilibrium we have 2 moles, so we have to think, that 2 moles have been reacted (4-2).
2 NH₃(g) → N₂(g) + 3H₂(g)
Initally 4moles - -
React 2moles 2m + 3m
Eq 2 moles 2m 3m
We had produced 2 moles of nitrogen and 3 mol of H₂ (ratio is 2:3)
The expression for K is: ( [H₂]³ . [N₂] ) / [NH₃]²
We have to divide the concentration /2L, cause we need MOLARITY to calculate K (mol/L)
K = ( (2m/2L) . (3m/2L)³ ) / (2m/2L)²
K = 27/8 / 1 → 3.37
Although there isn’t a picture a graph can be misleading when it doesn’t start at zero, it doesn’t give accurate information, it skips too many numbers, the vertical scale is too big or too small. Hope this helps
The heavily crosslinked polyethylene that has a glass-transition temperature of 0°c to be an <u>thermoset (non-elastomer).</u>
A cross-linked kind of polyethylene has been known as cross-linked polyethylene, sometimes known by the acronyms PEX, XPE, or XLPE. It must be primarily utilized in residential water piping, high tension electrical cable insulation, hydronic radiant heating as well as cooling systems, construction management pipework systems, and infant play mats.
Tanks composed of linear polyethylene as well as XLPE are both constructed using heated resins to produce cured plastic. But because of the variations in how they are produced, the polyethylenes they produce have extremely varied structural strengths. Simply put, cross-linking is just the creation of links between polymer chains.
Therefore, the correct answer will be option (a).

Answer:
Peptide bonds form from nucleophilic attack by an α‑carboxyl carbon atom on an electron pair of an α‑amino nitrogen atom of another amino acid.
Explanation:
Peptide bond is a form of covalent bond and it is Amide type that is formed between two molecules when carboxyl group react with one molecule of amino group to release molecule of water.The peptide bond are in form pseudo-double bond characteristic; rigid, planar, and stronger than a typical Carboxyl nitrogen single bond.
Peptide bonds form from nucleophilic attack by an α‑carboxyl carbon atom on an electron pair of an α‑amino nitrogen atom of another amino acid.
Acetaldehyde, ethyl acetate, ethanol, than acetic acid. it goes like that because its asking which one will be collected first
a,c,e is pure substance because the yellow is the same as a which is a pure substance and B,d are mixtures
