Correct Answer: D) A P-block element

Explanation

First, let's understand the electronic configuration given: 1s\(^2\), 2s\(^2\), 2p\(^6\), 3s\(^2\), 3p\(^4\). This configuration shows the distribution of electrons in the energy levels and sublevels of the element's atom.

To identify the element, we can add up the total number of electrons: 2 + 2 + 6 + 2 + 4 = 16 electrons. The element with 16 electrons is sulfur (S).

Now, let's analyze the options:

Option A: metal - Sulfur is a non-metal, so this option is incorrect.

Option B: An alkaline earth metal - Alkaline earth metals belong to Group 2 of the periodic table and have their outer electrons in the S sublevel (specifically, in the form of ns\(^2\). Sulfur does not fit this description, so this option is incorrect.

Option C: An S-block element - S-block elements are found in Groups 1 and 2 of the periodic table, and their outer electrons are in the S sublevel. Sulfur's outer electrons are in the 3p sublevel, so this option is incorrect.

Option D: A P-block element (Correct) - P-block elements are found in Groups 13-18 of the periodic table, and their outer electrons are in the P sublevel. Sulfur is in Group 16, and its outer electrons are in the 3p sublevel, so this option is correct.

In summary, an element with the electronic configuration 1s\(^2\), 2s\(^2\), 2p\(^6\), 3s\(^2\), 3p\(^4\) is sulfur, which is a P-block element.

Correct Answer: D. -2

Correct Answer: A) starch

Explanation

Mucor and Rhizopus are types of fungi that absorb carbohydrates in a specific form. The question is asking which form of carbohydrate is absorbed by these fungi. The options given are starch, sucrose, glycogen, arabinose, and glucose. Out of these options, the correct answer is starch. This means that when Mucor or Rhizopus fungi absorb carbohydrates, they do so in the form of starch. Starch is a complex carbohydrate that is made up of many glucose molecules linked together. When starch is broken down by enzymes in the fungi, it is converted into glucose which the fungi can then use for energy. Sucrose, glycogen, arabinose, and glucose are also forms of carbohydrates, but they are not the form that is specifically absorbed by Mucor and Rhizopus. Sucrose is a disaccharide made up of glucose and fructose, while glycogen is a storage form of glucose in animals. Arabinose is a type of sugar found in plants, and glucose is a simple sugar that is a main source of energy for many organisms. In summary, the correct answer to the question is starch, which is the form of carbohydrate absorbed by Mucor and Rhizopus fungi. For more information, please see the recommended textbooks.

Correct Answer: A. consumers

Explanation

The invisible hand is a natural force that self regulates the market economy. An example of invisible hand is an individual making a decision to buy noodles and egg, that person decision will make the economic society as a whole better off. This individual(s) are consumers that indirectly influences market economy as regards, what to produce, when to produce, how to produce and for whom to produce

Correct Answer: D. spiritual

Correct Answer: B. 35 Naira

Correct Answer: D) 600K

Explanation

When dealing with gas behavior, we often use the gas laws to describe the relationship between the variables involved, such as pressure, volume, temperature, and amount of gas. In this case, we will apply Charles's Law, which states that the volume of a gas is directly proportional to its temperature when the pressure and the amount of gas are kept constant.

Mathematically, Charles's Law can be expressed as:

\[\frac{V_1}{T_1} = \frac{V_2}{T_2}\]

Where \(V_1\) and \(T_1\) are the initial volume and temperature, and \(V_2\) and \(T_2\) are the final volume and temperature.

In this question, we are given that the initial volume of the gas (\(V_1\)) is 2 dm
