Correct Answer: C. uniformity in structure and functions

Correct Answer: C. withdraw

Correct Answer: A. the protagonist

Correct Answer: A. executive

Explanation

(a)(i) This can be defined as the number of atoms or molecules in one mole of a substance which is equal to 6.02 x 10\(^{23}\)

(ii) Mass/m.m = no. of molecules / Avogadro's number

(2.30 / m.m) x (3.01x10\(^{22}\) / 6.02 x 10\(^{23}\))

m.m = (2.30 x 6.02 x 10\(^{23}\)) / 3.01 x 10\(^{22}\)

m.m = 46g / mol

\(\therefore\) 14+('16 x 2)

14 + 32 = 46g /mol

\(\therefore\) No\(_{2}\)

(b)(i) I. Two layers are formed / no reaction / immiscible

II. there is a reaction / hydrolysis with steamy fumes /white fumes

(ii) The reaction occurs by interaction of the tones pair of electrons of water binding to the central atom (silicon or carbon) / attaching to the central atom In silicon, the 3p - orbital is available to accept the pairs of electrons but in carbon, there is no vacant orbitals for bonding.

OR

Water is polar hence the reaction with SiCI\(_{4}\). But CCI\(_{4}\) is non-polar hence there is no reaction

Correct Answer: C. a cypsela

Correct Answer: B. Ezekiel

Explanation

The prophet Ezekiel had a vision of a wheel within a wheel, which is recorded in the Book of Ezekiel in the Bible. This vision symbolizes God's divine presence and sovereignty, showing that God is omnipresent and has control over all things.

Correct Answer: D) Digital

Explanation

The correct answer is Option D: Digital.

A digital computer is a type of computer that uses discrete numbers, such as 0s and 1s, to represent and process information. These computers use a binary system to perform calculations, where data is represented using a series of bits. Each bit can have a value of either 0 or 1, and these values are used to perform mathematical operations such as addition, subtraction, multiplication, and division.

Digital computers are the most common type of computer used today. They are used in a wide range of applications, from personal computers and smartphones to large-scale mainframe computers. Digital computers are known for their accuracy and precision in performing calculations, making them well-suited for tasks that require high levels of mathematical processing.

In contrast, the other options in the question are not correct:

- Option A: Mainframe refers to a type of large and powerful computer that is often used by organizations to process large amounts of data and support multiple users simultaneously. However, the term mainframe does not specifically refer to a type of computer that performs mathematical calculations using discrete numbers.

- Option B: Analogue refers to a type of computer that uses continuous signals to represent and process information. These computers operate based on physical properties such as voltage or current, rather than discrete numbers. Analogue computers are less common today and are often used for specialized tasks such as simulations or scientific experiments.

- Option C: Hybrid refers to a computer system that combines characteristics of both digital and analogue computers. These systems may use digital components for certain tasks and analogue components for others. However, the term hybrid does not specifically refer to a type of computer that performs mathematical calculations using discrete numbers.

Therefore, the correct answer to the question is Option D: Digital.

Correct Answer: B)

Rate = \(K[A]^0[B]^2\)

Explanation

The question is asking about a chemical reaction between gases A and B that produces gas C. The rate of appearance of gas C has been found to be independent of the concentration of gas A, but to increase fourfold when the concentration of gas B is doubled. The question wants us to determine the rate law for the reaction.

The rate law describes the relationship between the concentration of the reactants and the rate of the reaction. From the experimental data, we know that the rate of the reaction depends only on the concentration of gas B, and not on the concentration of gas A. This means that the rate law must contain [B] raised to some power, but [A] raised to the power of zero.

The options given are different possible rate laws for the reaction. Option A has [A] raised to the power of zero, but also has [B] raised to the power of 4, which is inconsistent with the experimental data. Option B has [A] raised to the power of zero and [B] raised to the power of 2, which agrees with the experimental data. Option C has [A] raised to the power of 1, which is inconsistent with the experimental data. Option D has [A] raised to the power of 2, which is also inconsistent with the experimental data.

Therefore, the correct answer is Option B: Rate = \(K[A]^0[B]^2\). This means that the rate of the reaction is proportional to the square of the concentration of gas B, and is independent of the concentration of gas A. This question relates to the study of chemical kinetics, which is the study of the rates of chemical reactions and the factors that affect them. The rate law is an important concept in chemical kinetics, and it is used to describe how the rate of a reaction depends on the concentrations of the reactants.
