Explanation

Burning magnesium reacts with N₂ to form magnesium nitride (Mg₃N₂).

It also burns in CO₂, breaking it down to MgO and C.

Explanation

Look at the number of distinct digits in each addend: 100 has digits {1,0} → 2 distinct; the other 100 also has 2 distinct.

The code concatenates those counts, so 2 and 2 → 22.

Explanation

according to the graph, It is clear from the diagram that finally A was walking in the west direction.

Explanation

Rule: third number = 2 × (second number) − 4.

Check: for row3 → 2×58 − 4 = 116 − 4 = 112.

Explanation

Pain & Agony, Risk & Danger, Honesty & Integrity are synonyms (similar meaning).

Bondage & Freedom are antonyms (opposite meaning).

Explanation

Rule: split the word into groups of three (left to right) and write each trio in the order 3-2-1; the final pair is written as 2-1.

PRODUCED → PRO | DUC | ED → ORP | UDD | EC → ORPUDDEC.

Explanation

Rule: letters are swapped in adjacent pairs (1↔2, 3↔4, 5↔6, 7↔8).

Applying it to SUBLEASE (S U B L E A S E) gives U S L B A E E S = USLBAEES.

Explanation

Plane, cloud and eagle are found in the sky — they fly or float.

Squirrel is terrestrial/arboreal and cannot sustain powered flight (at best some species only glide).

Explanation

Each letter is shifted one forward in the alphabet (M→N, A→B, etc.).

Applying that to BOMBAY gives B→C, O→P, M→N, B→C, A→B, Y→Z → CPNCBZ.

Explanation

Step 1: Smallest triangles

If we look at the smallest possible divisions:

• Top section: 4 small triangles

• Bottom left: 2 small triangles

• Bottom right: 2 small triangles
  Total smallest ones = 8

Step 2: Medium triangles (made of 2 or 3 small ones)

• Top part: 2 medium triangles (one on left, one on right)

• Bottom part: 2 medium triangles (left, right)
  Total medium = 4

Step 3: Larger triangles inside main shape

• One triangle formed by the top half (entire top section)

• One triangle formed by bottom left section

• One triangle formed by bottom right section
  Total larger ones = 3

Step 4: The whole triangle

• The largest triangle is the whole outline = 1

Grand total = 8 (small) + 4 (medium) + 3 (large) + 1 (whole) = 16 triangles
