Question

5. During the chemical reaction the splinter burns and pop sound produced. Identify the
correct chemical reaction.
(1) CO, + 2NaOH - Na,Co, + H,0
(2) MgO + 2HCl (dil) - MgCl2 + H,0
(3) Zn + 2HCl (dil) - ZnCI, + H,
(4) H₂O₂ H₂ + O₂​

Answer 1

Answer:

Option (4)

Explanation:

When hydrogen is burnt, it is actually goes through a chemical reaction where it combines with oxygen to form water releasing a lot of energy.

The pop sound comes from the small explosion formed by the burning of Hydrogen with oxygen. Normally other gasses, such as water vapour, nitrogen, and carbon dioxide do not react easily with oxygen and hence no pop up sound is also produced
