No. Copper will not react with most acids. It will react with nitric acid to produce nitrogen dioxide. Gold and platinum will not react with nitric acid but will react with aqua regia, a mixture of hydrochloric and nitric acids to produce nitrogen dioxide and some nitric oxide. Rhenium does not react with acid at all.
No, hydrogen peroxide and alcohol are two very different substances.
The composition of hno3 is HNO3 , with one hydrogen atom, one nitrogen atom, and three oxygen atoms. The name of this molecule is nitric acid. Refer to the related link for a structural formula of nitric acid.
The products that are formed will be magnesium salt, water and carbon dioxide. Exactly what salt is made depends the acid used. Hydrochloric acid produces magnesium chloride; sulphuric acid produces magnesium sulphate; nitric acid produces magnesium nitrate.
Sodium and potassium
This may due to Magnesium metal has high reactivity and concentration of nitric acid is dilute, thus magnesium reacts with H+ in water/ in nitric acid to give hydrogen
Magnesium (Mg) + Nitric Acid (HNO3) ---> Magnesium Nitrate (MgNO3) + Hydrogen gas (H) + Heat
magnesium and manganese Mg(s) + 2 HNO3(aq) → Mg(NO3)2(aq) + H2(g)
magnesium nitrate + water + hydrogen
Magnesium will react with nitric acid and most other acids to produce hydrogen gas.
No; it prodces hydrogen gas instead: Magnesium is far above hydrogen in the electromotive series.
Manganese and magnesium are metals. They have a low electronegativity, which is to say, they have a weak grip on their valance electrons, and can easily lose them. Hydrogen is not as metallic - it is sort of halfway between a metal and a nonmetal although under normal conditions no one would ever mistake it for a metal - and it has a higher electronegativity; it holds on to its valance electron more strongly. Hence, the manganese and magnesium donate their electrons to the hydrogen ions which then become hydrogen gas, leaving behind the manganese and magnesium in the form of ions. The electrons simply migrate to the element that attracts them more strongly.
It is because nitric acid is a strong oxidising agent (because it decomposes to yield nascent oxygen as:2HNO3 →2NO2 + H2O + [O])and it oxidises the hydrogen formed to water.Only 1% dilute and cold nitric acid reacts with magnesium and manganese to liberate Hydrogen gas.
nitric acid + magnesium carbonate → salt + water + carbon dioxide
Magnesium reacts with Nitric Acid to produce Magnesium nitrate plus Hydrogen gas. Mg + 2HNO3 ----> Mg(NO3)2 + H2
You can make magnesium nitrate by mixing nitric acid and magnesium metal. However, the reaction creates heat and releases hydrogen gas. Depending on the percentage of nitric acid and the purity of the magnesium, depends on how much heat and how much hydrogen you'll get. I would personally be careful if trying this due to that when you have heat and hydrogen gas, you will probably get a flame. (maybe an explosion) So be careful if you are trying this experiment!
This is a single displacement reaction, so Mg (s) + HNO3 --> H (g) + Mg(NO3)2 Magnesium (solid) and Nitric Acid yields Hydrogen (gas) and Magnesium Nitrate
