Resonance involves two forms of a compound. Isomerism involves two or more forms of an element. Reforming involves the rearrangement of molecule. This deals with a two forms of a molecule where the chemical connectivity is the same but the electrons are distributed differently around the structure.

To purify the distillate of impurities like unreacted ethanol, acids, water and ethoxyethane. Adding anhydrous calcium chloride and leave it to stand for a day to remove any water present in the mixture.

Rust is an iron oxide, a usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture.

Expression for equilibrium constant k = \(\frac{\text{concentration of product}}{\text{concentration of reactant}}\)

At constant pressure connotes Charle's law \(\frac{V_1}{T_1}\) = \(\frac{V_2}{T_2}\) \(\frac{2dm^3}{300k}\) = 2 x \(\frac{2dm^3}{T_2}\) T2= 600k

If the rules are followed, it is non-negotiable that +5 is the suitable answer to the question.

At high temperature and low pressure, the vanderwaal equation is reduced to ideal gas equation. i.e, [P + \(\frac{a}{v^2}\)] [v - b] = RT is reduced to PV = nRT Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure as the potential energy due to intermolecular forces, it becomes less significant compared with the particles kinetic energy and the size of the molecules, then it becomes less significant compared to the empty space between them.

When ΔH is negative, heat is liberated to the surrounding and it connotes an exothermic reaction. ΔH = −ve

\(^{226}_{88}Ra\) → \(^x_{86}Rn\) + \(^4_{2}He\) \(^4_{2}He\) = alpha particle considering the summation of the mass number 226 = x + 4 x = 226 - 4 x = 222

The ammonia (NH\(_3\)) molecule has a trigonal pyramidal shape, with the three hydrogen atoms and the nitrogen atom forming a pyramid, and a lone pair of electrons on the nitrogen atom. Trigonal pyramidal and trigonal planar are distinct molecular geometries; trigonal planar has three atoms bonded to a central atom in a flat, triangular arrangement, while trigonal pyramidal has three atoms and one lone pair around the central atom, resulting in a pyramid shape.

Recall that mass deposited = \(\frac{MmIt}{96500n}\) Mm =108, t = 4830s I = 10A, n = 1 m = 108 \times 10 \times (\(\frac{4830}{96500}\)) \times 1 m = 54.0g

C5H12 has 5 carbons acid 12 hydrogens. 2–methyl butane No of carbon=5 No of hydrogen=12

Xanthopreitic test for the presence of protein, when conc nitric acid is added to the drop, an intense yellow colouration is observed. It contains all the functional group of protein which includes the amino, alkanol and the carboxylic group. Adding few drops of conc HNO3 to a protein, gives an intense yellow colouration. It is called Xanthopreitic test.

PH = - Log[ H+ ] PH + POH =14 POH = 14 - 3.8 POH = 10.2 POH = - Log[ OH- ] 10.2 = - Log[ OH- ] 10-10.2 = [ OH- ] [ OH- ] = 6.3 x 10-11

C2H5OH → CH3CHO → CH3COOH Ethanol.....oxidation Ethanal........Ethanoic Acid Primary alcohol oxidises to aldehyde and later to carboxylic acid. Secondary alcohol oxidises to ketones. Ethanol is an example of primary alcohol and primary alcohol can be oxidised to aldehyde and carboxylic acid. Wherein, incomplete oxidation of primary alcohol yields aldehyde also known as alkanal while complete oxidation of primary alcohol yields carboxylic acid.
