Sulfuric acid?
Mg + H2SO4 -> MgSO4 + H2
You produce magnesium sulfate ( a salt ) and hydrogen gas. ( you should see many bubbles of the hydrogen gas in solution )
Sulfuric acid is H2SO4
Will obtain magnisium nitrate{Mg(NO3)2} and H2 gas
When magnesium and hydrochloric acid are combined, a chemical reaction occurs where hydrogen gas is produced and magnesium chloride is formed. This reaction is exothermic, meaning it releases heat, and bubbles of hydrogen gas are visible as the reaction takes place.
When magnesium ribbon is added to acetic acid, a chemical reaction occurs which produces hydrogen gas and magnesium acetate. The magnesium ribbon will dissolve as it reacts with the acetic acid, releasing bubbles of hydrogen gas in the process. This can be observed by the fizzing or bubbling that occurs.
When magnesium ribbon is placed in hydrochloric acid, a chemical reaction occurs. The magnesium reacts with the hydrochloric acid to form magnesium chloride and hydrogen gas. This reaction is exothermic, meaning it releases heat energy.
When hydrochloric acid is mixed with an alkali, such as sodium hydroxide, water and a salt are formed. There is no gas produced in this reaction.
When magnesium ribbon is placed in nitric acid, a chemical reaction occurs where magnesium reacts with the nitric acid to form magnesium nitrate, water, and nitric oxide gas. The magnesium ribbon dissolves and bubbles form as the gas is produced.
The reaction of a magnesium ribbon fizzing in acid is a chemical change. This is because new substances are formed during the reaction as the magnesium reacts with the acid to produce magnesium ions and hydrogen gas.
I don't know for sure, but it is probably exothermic. (PLEASE CORRECT ME!)
In most cases, hydrogen is the gas evolved as the result of an acid and a magnesium ribbon. But in some instances when it reacts with a concentrated acids, it may produce different gases as well. As an example, the reaction between magnesium and concentrated sulfuric acid produces sulfur dioxide.
Submerging the magnesium ribbon in a strong acid solution like hydrochloric acid would cause it to react rapidly, producing magnesium chloride and hydrogen gas. The vigorous reaction would lead to the magnesium ribbon dissolving or disappearing within seconds.
When magnesium ribbon is added to hydrochloric acid, a chemical reaction occurs that releases energy in the form of heat. This reaction produces magnesium chloride and hydrogen gas, which results in an increase in temperature of the solution.
