Answer:
XY → X + Y general reaction represents a decomposition reaction where a molecule is “broken” in two separate molecules
Explanation:
In a double-displacement reaction two molecules will exchange atoms or group of atoms, and it should look like this:
XY + AB → XA + YB
In a combustion reaction molecules are reacting with oxygen generating oxides.
XY + O
→ XO + YO
In a single-displacement reaction an atom or a group of atoms in a molecule are replaced by other atoms, and it should look like this:
XY + A → XA + Y

The frequency of a 4,600 cm wave is 652 Hz
Frequency is the number of waves that pass a fixed point in unit time
Here given data is
Wave = 4,600 cm = 4.6 × 10⁸ nm
We have to calculated frequency = ?
Frequency =v = c/λ
Frequency = 3×10⁸m / 4.6 × 10⁸ nm
Frequency = 652 Hz
