Silicon (Si) and water - Lenntech
Silicon tetra chloride reacts with water quite violently. Silicides of the first and second group are generally more reactive than transitory metals. Typical reaction products include hydrogen and/ or silanes (SiH 4 ), for example Na 2 Si + 3H 2 O -> Na 2 SiO 3 + 3H 2 .
Metals and Non-Metals - CBSEGuess
When a metal reacts with dilute nitric acid, then hydrogen gas is not evolved. ( Nitric acid is a strong oxidizing agent , so, as soon as H 2 is formed the nitric acid oxidizes it to water.) Very dilute nitric acid reacts with magnesium and manganese metals to evolve hydrogen gas.
Specific Hazards Arising from the Material: Material readily reacts with water generating flammable hydrogen gas. May emit fumes of calcium oxide and/or calcium hydroxide under fire conditions. Special Protective Equipment and Precautions for Firefighters : Full face, self-contained breathing apparatus and full protective clothing to prevent contact with skin and eyes.
