They work together to form an organ.
Answer:
IR provides structural information about a molecule. TLC and melting point analysis do not provide structural information.
Explanation:
IR gives information about the functional groups present in a molecule. The vibrational frequency of each functional group gives information about the structure of the entire molecule.
Structural features of a molecule are deduced by matching the vibrational frequencies of groups obtained from the IR spectroscopy with that of known functional groups in literature.
Melting point is a qualitative method that can only yield information about the identity of a compound and not its structure. Each compound has its unique melting point recorded in literature and any pure sample of the same compound must have the same sharp meting point.
Thin-layer chromatography (TLC) is a chromatography technique used to separate non-volatile mixtures. After separating the components of the mixture, it does not give any information regarding the identity or the structure of the components of the mixture.
Therefore, only IR yields structural information about a sample.
Answer:
Explanation:
CH₄ + H₂O(g) ⇒ CO(g)+3H2(g)
Equilibrium constant
K₁ = [CO][H₂]³ / [CH₄][H₂O]
CO(g)+H₂O(g) ⇒ CO₂(g) + H₂(g)
Equilibrium constant
K₂ = [CO₂][H₂] / [CO][H₂O]
CH₄(g)+2H₂O(g) ⇒ CO₂(g)+4H₂(g)
Equilibrium constant
K = [CO₂][H₂]⁴ /[CH₄][H₂O]²
= [CO][H₂]³ / [CH₄][H₂O] X [CO₂][H₂] / [CO][H₂O]
K₁ x K₂
K = K₁ x K₂
Answer:
The coefficient with water is 6.
Explanation:
Chemical equation:
NH₃ + O₂ → NO + H₂O
Balanced chemical equation:
4NH₃ + 5O₂ → 4NO + 6H₂O
When ammonia and oxygen react nitric oxide and water produced.
Nitric oxide is gas and decompose in air.
The coefficient with water is 6 and equation is correctly balanced.
There are four nitrogen atoms, twelve hydrogen atoms and ten oxygen atoms on both side of equation.
Coefficients with reactant and product:
NH₃ 4
O₂ 5
NO 4
H₂O 6
Answer: of liquid sodium is required.
Explanation: To calculate the mass of liquid sodium, we use the formula:
where,
q = heat required, (Conversion factor: 1MJ = 1000000J)
m = Mass of liquid sodium,
M = Molar mass of liquid sodium,
c = Specific heat capacity,
= change in temperature, (Conversion factor: 0°C = 273K)
Putting values in above equation, we get:
