Alkali metals such as lithium, sodium, and potassium react with air by forming oxides or peroxides. These reactions can release heat and hydrogen gas, and may also cause fires or explosions. It's important to handle alkali metals carefully to prevent accidents.

It depends what you mean by slowly! Calcium burns in air and reacts fairly quietly with water, certainly much more slowly than the alkali metals do.

When a acid reacts with an alkali what are the twp products are formed what are they?

When an acid reacts with an alkali, the two products formed are salt and water. This reaction is called neutralization, where the acid donates a proton (H+) to the alkali to form water, and the remaining ions from the acid and alkali combine to form a salt.


Why is there a temperature changes when alkali is added to vinegar?

When an alkali (base) is added to vinegar, the acetic acid in the vinegar reacts with the alkali. These reactions are nearly all exothermic, that is, they generate heat as the chemical reaction proceeds. This is observed by a change in the temperature of the aqueous solution and the surrounding air.
