Correct Answer: B. Total mass of gas evolved during the reaction

Correct Answer: A) 4f

Explanation

In this question, the electron is described with n = 4 and l = 3. The value of l indicates that the electron is in a d orbital. The d orbitals have a complex shape and can hold a maximum of 10 electrons. The possible values of ml for l = 3 are -3, -2, -1, 0, 1, 2, and 3, which means that there are seven possible d orbitals.

The correct answer to this question is option A: 4f. The f orbitals have a more complex shape than the d orbitals and can hold a maximum of 14 electrons. The f orbitals are found in the fourth and higher energy levels, and since n = 4 in this question, the electron can be located in the 4f orbital.

To summarize, this question is testing your knowledge of quantum numbers and their relationship to the location of electrons in orbitals. The correct answer is 4f, which is a type of orbital with a complex shape that can hold up to 14 electrons.

Correct Answer: C. larger and fewer along the food chain

Correct Answer: C. Polonius

Correct Answer: D. techonolgical environment of business

Explanation

(a) Land And Sca Freezes: Breeze exchange between the land and the sea is attributed to differential heating of land and sea. These local wind are common in areas very close to the sea. During the day, the land is heated much faster than the sea and it is cooler than the sea at night. As the land is heated during the day, it causes the air to rise, creating a low pressure situation. Air therefore blows from the sea to replace the heated and rising air on the land thereby resulting in lower temperature and relatively cool air on the land. This is sea breeze which blows from sea to land. At night, the land becomes cooler that-. the sea having lost much of its temperature at a much faster rate than the sea. Thus, there is a high pressure situation on the land and a relatively low pressure situation on the sea. Hence a land breeze blows from the land to the sea.

(b) Temperati.re inversion:This is the opposite of lapse rate and it means a rise in temperature with increasing altitude. It is not in all cases that temperature decreases with altitude. Temperature could be lower at the sea-level especially in valleys almost enclosed by mountains than at heights above such valley E.g temperature inversion is found in European Alps where cold and heavy al: collects in valleys which are almost totally enclosed by mountains

(c) Convectional rainfall:This is the main type of rainfall in the humid tropics. The heat generated by the sun is aL;le to make the surroundings including the sea and ocean to be hot. Because the air is hot, it is able to absorb very large amount of moisture. The warm and moist air is forced to rise rapidly by convection current. When the current rises very high and reaches the cold layers of the atmosphere which make it conducive for the moisture contained in tha currents to condense, rainfall immediately fo: ows the condensation of the moisture. This type of rain formed by this process is called convectional rainfall.

Correct Answer: C. creditors control account

Explanation

The purchases ledger control account is also known as the creditors control account. This account is used in a business's accounting to record the total amount owed to suppliers for purchases made on credit. It is a summary account that reflects the total amount payable to all suppliers.
