Correct Answer: D. was time we did away with JAMB

Explanation

The correct answer option is D. was time we did away with JAMB.

Why Option D is Correct

Sequence of Tenses (Tense Concord): The main verb in the sentence is suggested, which is in the past tense. According to the rules of sequence of tenses, the verbs in the subordinate clause that follows must report backwards in time. Therefore, the present tense is time must change to the past tense was time.

Subjunctive / Unreal Past Construction: The idiom It is time or It was time followed by a subject (in this case, we) requires the use of a past subjunctive verb form to express something that should have been done already. Therefore, do must become did. Combining both rules gives us was time we did....

Correct Answer: C. 1.2 X 10²⁴

Explanation

To find the number of oxygen atoms in 32g of oxygen gas, follow these steps:

1. Determine the chemical formula of oxygen gas: Oxygen gas exists as a diatomic molecule, O₂.

2. Calculate the molar mass of oxygen gas (O₂):

* The atomic mass of oxygen (O) is given as 16 g/mol.

* The molar mass of O₂ = 2 * (atomic mass of O) = 2 * 16 g/mol = 32 g/mol.

3. Calculate the number of moles of oxygen gas (O₂) in 32g:

* Number of moles = Mass / Molar mass

* Number of moles of O₂ = 32 g / 32 g/mol = 1 mol.

4. Calculate the number of oxygen molecules (O₂) in 1 mole:

* Avogadro's number (L) is 6.0 X 10²³ particles per mol.

* Number of O₂ molecules = 1 mol * 6.0 X 10²³ molecules/mol = 6.0 X 10²³ molecules.

5. Calculate the number of oxygen atoms:

* Since each O₂ molecule contains 2 oxygen atoms, multiply the number of molecules by 2.

* Number of oxygen atoms = (Number of O₂ molecules) * 2

* Number of oxygen atoms = (6.0 X 10²³ molecules) * 2 = 12.0 X 10²³ atoms.

6. Express the answer in standard scientific notation:

* 12.0 X 10²³ = 1.2 X 10²⁴ atoms.

Comparing this to the given options:

A. 3.2 X 10²³

B. 6.0 X 10²³

C. 1.2 X 10²⁴

D. 1.6 X 10²⁴

The calculated number of oxygen atoms is 1.2 X 10²⁴.

The final answer is 1.2 X 10^{24}

Correct Answer: D. at all times and in all matters

Explanation

Islam has taken a strong position against visitation of fortune tellers and the art of fortunetelling. The Islamic ruling with regard to a Muslim who visits a fortuneteller and believes what he (the fortuneteller) tells him or believes that the fortuneteller knows the unseen and the future, is that it is kufr (disbelief), according to the scholars. They based their evidence on the saying of Allah: With Him are the Keys of the Ghayb (unseen); none knows them but He.(Qur'an 6:59).

Correct Answer: A. Reduction occurs at the anode

Explanation

The correct answer is A. Reduction occurs at the anode.

• In all electrochemical cells (including electrolytic cells), oxidation always takes place at the anode, while reduction takes place at the cathode (remember the mnemonic: An Ox, Red Cat).

• B is correct because negatively charged ions (anions) migrate toward the positively charged anode.

• C is correct because positively charged ions (cations) migrate toward the negatively charged cathode.

• D is correct because the concentration of an ion in the electrolyte is one of the factors that can influence its preferential discharge at an electrode.

Correct Answer: B. persistence of a high pressure belt over the area
