Question

Action of water or dilute mineral acids on metals can give:

• A. Monohydrogen
• B. Tritum
• C. Dihydrogen
• D. Trihydrogen

Answer 1

The correct option is C Dihydrogen

Action of water on dilute mineral acids $(HCl,H_{2}S{O}_4)$ can given dihydrogen.
Example:
$Mg+HCl\to H_2+MgC{l}_2$
$Mg+H_{2}O\to H_2+MgO$
Hence, the correct answer will be option (c).
