. Find out the molecular mass of Acetic Acid

Answer:

1. The IUPAC name of the compound is [Cr(NH 3) 6] 3+ is Hexamminechromium(III) ion.

Explanation:

1. The IUPAC name of the compound is [Cr(NH 3) 6] 3+ is Hexamminechromium(III) ion.

Explanation:

Correct option is A)

When there is an interchange of the sentence from comparative to positive, without changing its meaning, a negative word 'no' or 'not' is added. Here the sentence is in the comparative degree. As 'Harry' is taller than 'brother', the brother is shorter than 'Harry.' In other words, the brother is 'not as tall as' Harry. Option A is correct because the sentence is of the positive degree of comparison using 'not as tall as', without changing the meaning of the sentence. Option B is incorrect because the adjective 'very' is not a comparative and the sentence is not of the positive degree. Option C is incorrect because it is opposite in meaning to that of the given sentence, where the 'brother' is taller than 'Harry'. Option D is grammatically incorrect.

Answer:

The degree of comparison that is used in the sentence "Ram is taller than Mohan" is the comparative degree of comparison.

Explanation:

• The three degrees of comparison that can be used are positive, comparative and superlative.
• The positive degree of comparison establishes the existence of quality is mentioned. This sentence can be rewritten to represent the positive degree as "Ram is as tall as Mohan".
• The structure "as + adjective +as" denotes the positive structure and the adjective is used in its root word form.
• The comparative degree is used to compare two things and establish an order of superiority. The given sentence is in this form.
• The comparative degree uses the adjective with the suffix "-er."
• The superlative degree establishes something as superior to everything else. This sentence can be rewritten to represent the superlative degree as "Ram is the tallest".
• The superlative degree uses the adjective along with the suffix "-est".

I hope this help you

Given,

The student's ages are in A.P.

The common difference  = 3 months.

The younger student's age = 12.

The total age = 375yrs.

To Find,

The count of students in the group.

Solution,

Given that,

The ages of students are in A.P.

The difference between their ages = 3months.

3/12 = 1/4yrs

The total of their age = 375yrs.

Younger one's age =12yrs.

In A.P, the sum of the terms

S = n/2 (2a +(n-1)d)

a =12.

S = n/2 (2*12+ (n-1)1/4)

S = 375

n/2(2*12+(n-1)1/4) = 375

n/2(24+(n-1)1/4) = 375

n(24+(n-1)1/4) = 750

n(24*4+(n-1)) = 750 * 4

n(96+(n-1)) = 3000

96n + [tex]n^{2}[/tex] -n = 3000

95n + [tex]n^{2}[/tex] = 3000

[tex]n^{2}[/tex] + 95n -3000 = 0

Let's factorise it.

[tex]n^{2}[/tex] + 120n -25n -3000 = 0

n(n+120) -25(n +120) = 0

So,

n = -120 or 25

Hence, 25is the total number of students in the group.
