. (i) Give two industrial applications of distillation under reduced pressure. (ii) Why is it necessary to use acetic acid and not hydrochloric acid for acidification of sodium extract for testing sulphur by lead acetate test?

Answers:

Ans. (i)Distillation Under Reduced Pressure is used for purifying or separating thermally unstable liquid compounds.
Uses :
 In Petroleum Refining
 in food processing
(ii) For testing of sulphur present in the organic compound, the Lassaigne’s extract is acidified with acetic acid (CH_{3}COOH) and not sulphuric acid because lead acetate is soluble and does not interfere with the test. If sulphuric acid (H_{2}SO_{4} ) is used, lead acetate will react with H_{2}SO4 itself to form white ppt. PbSO_{4.}

How many words with or without meaning can be formed from the letters of the word hcverma when 1) at least three consonants occupy the odd placed

Answers:

Total arrangements possible are 7P7 = 7! = 5040
There are 2 vowels & 5 cosonants => there is only one way when the given condition will not meet & that is when both these vowels will occupy the odd places. Now, the no. of ways it is possible = 4P2 * 5P5 = 12 * 120 = 1440
=> Total words which can be formed in the required fashion are 50401440 = 3600 (Answer)

what are the differences between balance sheet and trial balance?

Answers:

Ans. The differences are following:
 Statement of debit and credit balances were taken from general ledger is known as Trial Balance. Statement of assets and equity & liabilities is known as Balance Sheet.
 Trial Balance does not include closing stock while the Balance Sheet does not include opening stock.
 Trial Balance checks the arithmetical accuracy in the recording and posting while balance sheet is prepared to determine the financial position of the company on a specific date
 Trial Balance is prepared after posting into ledger whereas Balance Sheet is prepared after the preparation of Trading and Profit & Loss Account.
 The Balance Sheet is the part of the Financial Statement while Trial Balance is not a part of the Financial Statement.
 Balances of all personal, real and nominal account are shown in the trial balance. On the contrary, Balance sheet shows the balances of personal and real account only.
 The trial balance is prepared at the end of each month, quarter, half year or the financial year. Conversely, the balance sheet is prepared at the end of each month.
 The trial balance is prepared for internal use only, however, the balance sheet is prepared for both internal and external use, i.e. to inform outside parties about the financial condition of the entity.

Rhizosphera are pneumatophores or prop root?

Answers:
. Which species is the smallest aromatic substance?

Answers:

The cyclopropenyl cation is the smallest aromatic substance.
As to π electrons, when n = 0, the ordinary cyclopropene molecule is not aromatic. It becomes aromatic only if the third π electron is missing. That is, when it becomes the cyclopropenyl cation and its ring has a positive charge.

4tanx(1tan2x)/16tan2x+tan4x

Answers:

The question is : Prove that tan 4x= 4 tanx(1tan^{2}x)/16tan2x+tan^{4}x
L.H.S.
tan 4x = tan 2(2x)
[We know that tan 2x = 2 tan x / 1  tan^{ 2} x]
= 2 tan 2x / 1  tan^{2 }(2x)
[now putting tan 2x = 2 tan x / 1  tan^{2}x]
= 2[2 tan x/1tan^{2}x] / 1  [2 tan x / 1  tan^{2}x] ^{2}
=[4 tan x / 1  tan ^{2 }x] / [1  4 tan ^{2 }x / (1  tan^{2} x)^{2}]
=[4 tan x / 1  tan ^{2} x] / [ (1 tan ^{2} x^{)2}  4 tan ^{2 }x / (1  tan^{2} x)^{2}]
= 4 tan x (1  tan ^{2} x) / (1 tan ^{2} x)^{2}  4 tan ^{2} x
= 4 tan x (1  tan ^{2 }x) / 1  2 tan^{2} x +tan ^{4} x  4tan^{2} x
= 4 tan x (1  tan ^{2} x) / 1  6 tan ^{2} x + tan^{ 4 }x

Drive the formula for the magnitude of resultant of addition of two vectors

Answers:

If two vectors are considered to be the adjacent sides of a Parallelogram, then the resultant of two vectors is given by the vector which is a diagonal passing through the point of contact of two vectors.
The proof for the resultant vector in Parallelogram addition is as follows,
Consider a parallelogram OABC as shown in the figure,
<a href="https://i.stack.imgur.com/gHNkO.jpg" rel="nofollow noreferrer"></a>
Let P&Q be two adjacent sides of parallelogram, and R be the resultant vector obtained by addition of vectors P&Q.
Now, drop a perpendicular from C on OA so that they meet at A
From right angled triangle ΔOCD,
OC^{2}=OD^{2}+DC^{2}
[OD=OA+AD]
R^{2}=(OA+AD)^{2}+DC^{2}
R^{2}=OA^{2}+AD^{2}+2OA.AD+DC^{2}
From ΔADC,
AC^{2}=AD^{2}+DC^{2}
and also cosθ=AD/AC
And hence R^{2}=OA^{2}+AD^{2}+2OA.AD+DC^{2}
And substituting A and B
R^{2}=A^{2}+B^{2}+2A.Bcosθ

Explain me clearly the last paragraph of father to son

Answers:

The last paragraph says that fathers and sons all over the world should learn to live on the same globe and same land. In the end, the father has a realization that he is the one who cannot understand himself and gets angry. The father concludes that each one of them is willing to forgive the other but neither wants to take the first step. Respecting each other’s differences is the only way out to diminish the distance between parents and children.

sin5x2sin3x+sinx/cos5xcosx=tanx

Answers:

sin5x + sinx = 2sin3x cos2x
cos5x  cosx = 2sin3x sin2x ..... use factorisation formulae of trigonometry.
So the fraction is 2sin3x(cos2x1)/  2sin3xsin2x
= (1 cos2x)/sin2x
= 2(sin^{2}x)/ 2sinxcosx
=sinx/cosx
=tanx.Thanks (0)

What is capital expenditure and revenue expenditure

Answers:

An expenditure which neither creates assets nor reduces liability is called Revenue Expenditure, e.g., salaries of employees, interest payment on past debt, subsidies, pension, etc.
An expenditure which either creates an asset (e.g., school building) or reduces liability (e.g., repayment of loan) is called capital expenditure.

Find the depth of the well if sound heard after 4sec. of dropping the stone if speed of sound is 340m/sec.

Answers:

Now total time taken to hear the sound after dropping the stone = 4sec
It is time between throwing and listening
therefore time for sound to go from depth to the height = 2sec
speed of sound= 340m/s
therefore depth = time * speed
=2*340
=680m

What is relation between linear expansion or superficial expansion

Answers:

Ans. The amount by which unit length of a material increases when the temperature is raised by one degree is called the coefficient of linear expansion and is represented by \(\alpha\) (Greek alpha).
The amount by which unit area of a material increases when the temperature is raised by one degree is called the coefficient of superficial (i.e. area) expansion and represented by \(\beta\)(Greek beta).
Relation b/w both :
\(\beta = 2 \alpha\)

A big drop is formed by collapsing 1000 small droplets of water.What will be the change in the surface energy. What will be the ratio between total Surface energy of droplets and surface energy of Big drop.

Answers:

Ans. Let Radius of big Drop is R and Radius of Small Droplet is r.
Then
Volume of Big Drop = Volume of 1000 Small Droplets
=> \({4\over 3} \times {{\pi} } \times R^3 = {1000}{ \times }{4 \over 3 }{\times \pi \times r^3}\)
=> \(r = {1\over 10} \times R \)
The Surface Energy of 1000 Droplets = \(1000 [{T \times 4\pi r^2}] \)
=> \(1000 [{T \times 4 \pi ({R\over 10})^2}]\)
=> \(10 [T\times 4\pi R^2]\) ......... (1)
The Surface Energy of Big Drop = \(T \times 4\pi R^2\)
Ratio of Surface energy :
\(10 [T\times 4\pi R^2] : [T\times 4\pi R^2] = 10:1 \)
Surface Energy Decrease in This Case.
