Acids can react with metals.
yes
Because they can wear away metals and that produces hydrogen gas
Metals often wear each other away as a result of friction between adjoining surfaces.
Substances which are corrosive.
Constant erosion from wind and water makes the rock wear away. It's how canyons and mountains were formed.
Because they can wear away metals and that produces hydrogen gas
Hydrogen gas is given off when any acid reacts with metals. Acids must have at least 1 hydrogen in order to be recognized as an acid, so the metal takes the place of a hydrogen when it reacts and the metal becomes an ionic compound with whatever the hydrogen was bonded to in the acid and the hydrogen is on its own and is H2 gas.
Acids Wear Violence
its wear you mix acids to alkali
Acid rain is harmful because it is acidic. Acids wear away materials and eat through animals and plants that are too weak to hold up.
Eating foods with too many acids (lemons, sour candy, etc.) is bad for your teeth and will wear them away over a period of time.
When you gag, this causes the teeth and gums to be touched by stomach acids. The acid causes the teeth enamel to wear away thus causing tooth decay.
