What is the metal that reacts slowly with cold water to form a hydroxide?
The metal that reacts slowly with cold water to form a hydroxide is magnesium. When magnesium reacts with water, it forms magnesium hydroxide and hydrogen gas.
Is sulfur dioxide gas soluble in water?
Yes, sulfur dioxide gas is highly soluble in water. It reacts with water to form sulfurous acid (H2SO3), which then further reacts to form sulfite ions (SO3^2-).
What is the solubility in water of fluorine?
Fluorine is not soluble in water because it is a highly reactive gas that readily reacts with water to form hydrofluoric acid.
When methane gas reacts with oxygen what happen?
When methane gas reacts with oxygen, it undergoes combustion to form carbon dioxide and water vapor. This reaction releases energy in the form of heat and light. Methane (CH4) + 2O2 → CO2 + 2H2O.
Why ammonia gas cannot be dried by using conc.H2SO4 AND P2O5?
Ammonia gas cannot be dried using concentrated H2SO4 and P2O5 because ammonia gas reacts with both chemicals. Ammonia reacts exothermically with concentrated H2SO4 to form ammonium sulfate and water. Similarly, ammonia reacts with P2O5 to form ammonium phosphate and water. These reactions do not effectively dry the ammonia gas as the water byproducts are produced.
