Copper doesn't react wih alkalis.
Yes, alkalis can react with metals to form metal hydroxides and hydrogen gas. The reaction typically involves the alkali breaking down the metal's oxide layer to generate hydrogen gas and a metal hydroxide.
Yes, alkali can react with magnesium, particularly when magnesium is in its elemental form. In the presence of strong alkalis, such as sodium hydroxide, magnesium can react to form magnesium hydroxide and hydrogen gas. This reaction typically occurs at elevated temperatures or in the presence of water. However, magnesium does not react significantly with alkalis at room temperature.
It doesn't.
Alkali react with greases and oils forming water soluble soaps.
It forms copper oxide
No, acids and alkalis do not react in a combustion reaction. Combustion reactions involve a substance reacting with oxygen to produce heat and light. Acids and alkalis typically do not react in this way.
No, acids and alkalis do not react in a combustion reaction. Combustion is a chemical reaction that involves a substance combining with oxygen to produce heat and light. Acids and alkalis react in neutralization reactions, where they form water and a salt.

Alkalis and metals do not usually react.
When acids react with alkalis, they undergo a neutralization reaction to form salt and water. This process involves the transfer of protons from the acid to the alkali, resulting in the formation of a salt and water as the products.
When alkalis react with ammonium salts, they form ammonia gas, water, and the corresponding salt. This reaction is known as an acid-base reaction, where the alkali acts as the base and the ammonium ion acts as an acid. The ammonia gas is released as a byproduct of the reaction.
Copper does not react with nitrogen under normal conditions. However, at very high temperatures and pressures, copper can react with nitrogen to form copper nitride.
Aluminium is not an acid or a base, but it does react with both acids and alkalis.
Yes, alkali can react with magnesium, particularly when magnesium is in its elemental form. In the presence of strong alkalis, such as sodium hydroxide, magnesium can react to form magnesium hydroxide and hydrogen gas. This reaction typically occurs at elevated temperatures or in the presence of water. However, magnesium does not react significantly with alkalis at room temperature.
Hazards of alkalis include skin and eye irritation upon contact, potential respiratory irritation if inhaled, and risk of burns or corrosion if ingested. Alkalis are also caustic and can react dangerously with other substances if not handled properly.
Copper does not react in water.
