Explanation

We learn "about" someone when we gain information or understanding regarding them.

The source is the poem, so we say we learn this "in" the poem — where the information is found.

Explanation

Let's solve the expression 3(a ÷ b)^c with the given values: a = 36, b = 12, and c = 2.

First, calculate a ÷ b = 36 ÷ 12 = 3.

Then, raise it to the power of c: 3^2 = 9.

Finally, multiply by 3: 3 * 9 = 27.

Explanation

It directly reflects the effectiveness of teaching and the overall academic quality of the school.

High student achievement indicates successful learning outcomes, which is the main goal of education.

Explanation

When calcium carbonate (CaCO₃) reacts with dilute hydrochloric acid (HCl), it produces carbon dioxide (CO₂) gas.

The reaction is:

CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O

Explanation

Assessment is the broader process of collecting, synthesizing, and interpreting information about learning or performance.

It supports decision-making by identifying strengths, weaknesses, and progress in a learner’s development.

Explanation

S.N.E (Schedule of New Expenditure) is a government document used to propose and approve new budgetary expenditures.

It is essential for creating new posts, purchasing items, or initiating new projects in public departments.

Explanation

Noble gases like helium, neon, and argon are placed in Group VIII (Group 18 in modern IUPAC numbering).

They are inert.

They have a full outer electron shell.

It making them stable and unreactive.

Explanation

Bus width affects how much data can be transferred at once.

System clock speed controls how fast instructions are processed.

Memory access time determines how quickly data can be read/written.

Explanation

Hydrochloric acid (HCl) reacts with Sodium hydroxide (NaOH) to form Sodium chloride (NaCl) and Water (H₂O) — a typical acid-base neutralization reaction.

The balanced equation is:

NaOH + HCl → NaCl + H₂O

Explanation
