Correct Answer: A) 4

Explanation

In order to understand the question, you need to know what a straight-chain dichloroalkane is. A straight-chain dichloroalkane is an alkane with two chlorine atoms replacing two hydrogen atoms on a linear carbon chain. The formula given is \(C_4H_8Cl_2\), which means the compound has 4 carbon atoms, 8 hydrogen atoms, and 2 chlorine atoms.

To find the number of different straight-chain dichloroalkanes, we need to identify the different positions the two chlorine atoms can be placed on the 4-carbon chain without repeating any arrangement.

Let's use numbers to represent the carbon atoms in the chain (1, 2, 3, and 4) and X to represent the positions of the chlorine atoms. We can have the following combinations:

1. 1,2 (XX00)
2. 1,3 (X0X0)
3. 1,4 (X00X)
4. 2,3 (0XX0)
5. 2,4 (0X0X)
6. 3,4 (00XX)

However, we need to consider that the chain can be flipped, and some of these combinations are identical when the chain is reversed. For example, combination 1 (XX00) is the same as combination 6 (00XX) when flipped. Similarly, combination 3 (X00X) is the same as itself when flipped. So, we only have 4 unique straight-chain dichloroalkanes:

1. 1,2 (XX00)
2. 1,3 (X0X0)
3. 1,4 (X00X)
4. 2,3 (0XX0)

Thus, the correct answer isOption A: 4.

Correct Answer: C. defect

Correct Answer: A) Belteshazzar

Explanation

In the book of Daniel in the Bible, we read about a man named Daniel who was taken captive by King Nebuchadnezzar of Babylon. When Daniel was brought to the king's palace, the king gave him a new name. This question is asking for that new name that King Nebuchadnezzar gave to Daniel.

The options given are: Belteshazzar, Hananiah, Mishael, and Azariah. The correct answer is Belteshazzar, which is Option A.

It's important to note that in ancient times, changing someone's name often signified a significant change in their identity or status. In this case, Nebuchadnezzar changed Daniel's name to Belteshazzar to reflect his new position as a wise man and an advisor to the king.

Overall, this question is testing your knowledge of the Book of Daniel and the character of Daniel himself. Remember that when you come across a similar question in your exams, you should read the question carefully and consider each option before selecting the correct answer.

Correct Answer: C. exchanging control

Correct Answer: A. \(-\frac{81}{8}, -\frac{729}{32}\)

Explanation

\(-2, -3, -4\frac{1}{2}, ...\)

This is a G.P with r = 1\(\frac{1}{2}\).

\(T_{n} = ar^{n - 1}\) (terms of a G.P)

\(T_{5} = (-2)(\frac{3}{2})^{5 - 1}\)

= \(-2 \times \frac{81}{16}\)

= \(-\frac{81}{8}\)

\(T_{7} = (-2)(\frac{3}{2})^{7 - 1}\)

= \(-2 \times \frac{729}{64}\)

= \(-\frac{729}{32}\)
