Functional group is ethanol

There are several ways you can distinguish between an acetaldehyde and an acetone.

# One of the most common ways to allow both acetaldehyde and acetone to react with Tollen’s reagent. A silver mirror is formed when acetaldehyde reacts with Tollen’s reagent. No such compound is formed on reaction of the agent with acetone.

# When acetone is subject to iodoform test, a precipitate is formed. There will be no such reaction when acetaldehyde is subject to iodoform test.

# Fehling’s reagent and chromic acid test can help in the identification of an acetaldehyde.

The isomer of ethanol (CH3CH2OH) is dimethyl ether(CH3OCH3). This is functional isomer of ethanol.

Always remember , two -OH group on one carbon is always unstable and it will C=O , by releasing H2O.

The structure is OH. O | ||C-C-C-C →C-C-C-C so, butanone will be formed | OH

The tartness ofbuttermilkis due toacidin the milk. The increasedacidityis primarily due to lacticacidproduced by lacticacidbacteria while fermenting lactose, the primary sugar in milk.

Amorphous solidsinclude both natural and man-made materials. The most frequently citedexampleof anamorphous solidis glass.

Ethanol has sweet odour while ethanoic acid has pungent odour.

Ethanol does not react with sodium bicarbonate (NaHCO₃) but ethanoic acid reacts with sodium bicarbonate (NaHCO₃) releasing CO2 gas.

Ethanol does not change the colour of blue litmus paper while ethanoic acid change the colour of blue litmus to red.

We can distinguish between ethanol and ethanoic acid by reacting them with a metallic carbonate like Na2CO3or a bicarbonate like NaHCO3.......

Ethanoic acid reacts to give to give CO2and no reaction takes place in case of ethanol.

2CH3COOH + Na2CO3----------> CH3COONa + H2O + CO2

CH3CH2OH +Na2CO3-------------> NO REACTION...

SAME CASE WITH NaHCO3.

milk and stratch solution will show tyndall effect because they are colloids.

Starch solution will show tyndall effect

And milk solution will also shows tyndall effect because of colloid nature...

The dirt on clothes cannot be cleaned or removed by only water. So we use soap, when we use soap it dissolves in water, its hydrophobic ends attach themselves to the dirt hence removing the dirt.I hope it will help u

thank you

(a) LPG --> cooking(b) Hottest part -->Blue(c) cutting of forest --> deforestation(d) lubricants --> oil and Grease(e) Magnitude --> strength of force

Cooking of food is an irreversible change. Because after cooking and he food gets changes to new substance , which connot be reversed again.

1) EmbryologySimilarities between embryos of complex animals.2)Geographical distribution

here are 4 points1.embryology2.fossil layer3.ancient organism remains4.similarities in DNAhope it helps u

The points can be:--Anatomy-Fossils-Biogeography

1.palentological evidence and 2.embryological evidence

i. An equilateral triangleis atrianglein which all three sides are equal. In the familiar Euclidean geometry,an equilateral triangleis also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

ii. A square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles

iii. In geometry,hexagonis apolygonwith 6 sides. If the lengths of all the sides and the measurement of all the angles are equal, suchhexagonis calleda regular hexagon. In other words, sides ofa regular hexagonare congruent.

iv. All sides are the same length (congruent) and all interior angles are the same size (congruent).

Ans :- TheBrownian movementhas been explained to be due to the unbalanced bombardment of the particles by the molecules of the dispersion medium. The Brownian movementhas a stirring effect which does not permit the particles to settle and thus, isresponsible for the stability of sols.

As temperatures increase, additional heat energy is applied to the constituent parts of a solid, which causes additional molecular motion. Molecules begin to push against one another and the overall volume of a substance increases. At thispoint, the matter has entered the liquid state.please like the solution 👍 ✔️

Biopharmaceutics examines the interrelationship of the physical/chemical properties of the drug, the dosage form (drug product) in which the drug is given, and the route of administration on the rate and extent of systemic drug absorption.

true, fibre is a material that is woven from threads

True , Fibre is a material that is woven from threads

2) is correct answer

option c is the correct answer

Kraftis define as the minimumtemperatures form micelles. It is named after German chemist FriedrichKrafft. Below theKrafft temperature, there is no value for the critical micelle concentration (CMC), i.e., micelles cannot form.

Displacement Reaction: One element takes the placeofanother elementin acompound.Double displacement Reaction: Two compoundsreactby an exchangeofions to form two new compounds.

Al has 3 electrons in its last shell.so, Al can give all the 3 electrons to become most stable

so correct order is in option A

Ans :- Al2+2NAOH +2H2O =2NAAlO2+3H2

thanku very much

as alpha is 40% ionizedso i=1+alpha=1+0.4=1.4

a)The van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved in water, the van 't Hoff factor is essentially

Anisotonic solutionrefers to twosolutionshaving the same osmotic pressure across a semipermeable membrane. This state allows for the free movement of water across the membrane without changing the concentration of solutes on either side

c)The ratio of the elevation of the boiling point of a solvent caused by dissolving a solute to the molality of the solution, taken at extremely low concentrations. Also known as molal elevation of the boiling point

d)An azeotrope or a constant boiling point mixture is a mixture of two or more liquids whose proportions cannot be altered or changed by simple distillation. This happens because when an azeotrope is boiled, the vapour has the same proportions of constituents as the unboiled mixture

Thank you so much...

The Van't hoff factor for Hg2Cl2 is 1+2 = 3

and similar factor will be form Na2SO4 , 2+1 = 3

option 2

CH3-CH2-OH means Ethol

CH3- CH2-OH Means Ethanol

320 gram of O2 is needed. MgO formed = 800 gm

The ice cubes only float and not able to sink in the water.

If the water is at 0 degree Celsius, There is some change in the ice melts.

The ice melts slow down because of the absorption of the thermal energy.

The ice melts can minimize the temperature of the water by a single degree.

Ice cubes don’t sink in water, they float.

If you add water to a bucket full of ice, then some of the ice will melt, bringing the water temperature down to 0 degrees Celsius. Every gram of ice that melts will reduce the temperature of 80 grams of water by one degree.

Once the water is at 0 degrees, the rate at which the ice melts will slow down as it will have to adsorb [thermal] energy from outside the bucket, not from the water itself.

Let the pressure at the bottom =P1and volume =V1Let the pressure at the surface =P2and volume = V2​Temperature remains constant soP1V1= P2V2​Given that: V2= 4V1therefore, P1= 4P2

Pressure =hρgρ= density of waterg = acceleration due to gravity

​P2=hρg=10ρg​P1= 4(10ρg)

P1-P2=40ρg-10ρg=30ρg

From hydrostatics,P1-P2=hρg30ρg =hρgh = 30 m

Depth of the lake = 30m
