Answer:
092) Icosane
093) Ethene
Explanation:
092) The given compounds are;
Decane C₁₀H₂₂; Viscosity = 0.850 mPa·s (25°C)
Ethene C₂H₄ (gas); Viscocity ≈ 0.01038 m
Icosane C₂₀H₄₂; Solid at room temperature
Methane CH₄; gas at room temperature
The viscosity of the given carbon and hydrogen compounds is observed to increase with their molar masses
Therefore, icosane, which is a solid at room temperature, has the highest viscosity (resistance to deformation) out of the given compounds
093) Polymers are made from monomer alkene units, therefore, ethene, which is the only alkene among the given compounds can be used to produce a polymer
Polyethene is formed by the polymerization of ethene whereby molecules of ethene are joined together to form poly(ethene)
Answer and Explanation:
Photosynthesis reaction involves two reactants, carbon dioxide and water. These two reactants yield two products, namely, oxygen and glucose.
Answer:
A) 
.
B) 
.
C) 0.9 mol.
D) Increasing both temperature and pressure.
Explanation:
Hello,
In this case, given the information, we proceed as follows:
A)
B) For the calculation of Kc, we rate the equilibrium expression:
![Kc=\frac{[NH_3]^2}{[N_2][H_2]^3}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5BH_2%5D%5E3%7D)
Next, since at equilibrium the concentration of ammonia is 0.6 M (0.9 mol in 1.5 dm³ or L), in terms of the reaction extent 
, we have:
![[NH_3]=0.6M=2*x](https://tex.z-dn.net/?f=%5BNH_3%5D%3D0.6M%3D2%2Ax)
Next, the concentrations of nitrogen and hydrogen at equilibrium are:
![[N_2]=\frac{1.5mol}{1.5L}-x=1M-0.3M=0.7M](https://tex.z-dn.net/?f=%5BN_2%5D%3D%5Cfrac%7B1.5mol%7D%7B1.5L%7D-x%3D1M-0.3M%3D0.7M)
![[H_2]=\frac{4mol}{1.5L}-3*x=2.67M-0.9M=1.77M](https://tex.z-dn.net/?f=%5BH_2%5D%3D%5Cfrac%7B4mol%7D%7B1.5L%7D-3%2Ax%3D2.67M-0.9M%3D1.77M)
Therefore, the equilibrium constant is:
C) In this case, the equilibrium yield of ammonia is clearly 0.9 mol since is the yielded amount once equilibrium is established.
D) Here, since the reaction is endothermic (positive enthalpy change), one way to increase the yield of ammonia is increasing the temperature since heat is reactant for endothermic reactions. Moreover, since this reaction has less moles at the products, another way to increase the yield is increasing the pressure since when pressure is increased the side with fewer moles is favored.
Best regards.

mixture of iron powder and sulphur heated it glows because sulphur and iron are more reactive metals that they shine and sulphur can react with water produce fire it's write
Answer:
acetyl-CoA.
Explanation:
Fatty acids are broken down into acetyl-CoA by the process of beta-oxidation inside the mitochondrial matrix part of the powerhouse of the cell. Whereas fatty acids are synthesized from acetyl-CoA in the mitochondria.
Then acetyl-CoA which is produced by beta-oxidation enters the citric acid cycle in the mitochondrion by combining with oxaloacetate to form citrate and then complete the combustion of the acetyl-CoA into carbon dioxide and water.
