Which gas is produced when a metal reacts with a dilute acid?
Will form a metal salt solution and hydrogen gas
What happened to a metal when exposed to an acidic mixture?
The acid deprotonates in aqueous solution, and the negative ions induce nucleophilic attack on the positively-charged metal ions, removing metal ions from the metal and combining with them to form a salt. The protons that dissociated into solution quite often recombine with each other to form diatomic hydrogen, which bubbles out of the solution as a gas. This process of removing metal ions from the metal itself to be recombined into a salt with the original acid is called corrosion. So, in a nutshell, the acid breaks down into ions, eats away bits of metal atoms from the original metal mass, combines into salt with the acid, and the hydrogen from the acid recombines to hydrogen gas, which bubbles out of the solution.

Is MnO2 an acid or a base or salt?
It is a simple metal oxide, which can make it a salt.
What is released when you mix metal with acid?
salt and hydrogen :)
What does an acid and metal equal?
In a typical case an acid and a metal will react to form hydrogen gas and a salt. The salt formed depends on what acid and what metal is used.
What Metal elements produces hydrogen gas when it is placed in hydrochloric acid?
Metal + Acid = Salt + Hydrogen Any metal that reacts with hydrochloric acid will form a metal chloride salt and hydrogen Sodium metal and hydrochloric acid
What compound reacts with acid to form salt?
Any metal
How does metal oxide react with acid?
A reaction between an acid and a metal oxide to form a salt and water as the only products.
How can a metal be defined?
Metal in broad sense can be defined as ... which reacts with acid to form salt and water.
What happens when you mix an acid with a metal oxide?
Generally metal oxides are soluble in acids but this is not mandatory. A metal salt is obtained as a product and hydrogen also.
What would you use to test if a metal has reacted with hydrochloric acid?
The metal would most likely form a metal salt.
What is the word equation between acid and metal hydroxide?
acid+ metal oxide --> salt + water
Metal plus acid?
Metal+Acid=Salt+Hydrogen
What happens when metal and acid?
Acid + Metal = Salt + Hydrogen
Can an acid and a base react to form an acid?
NO!!!! Remember the general acid reaction equations. Acid + Base = Salt +Water Acid +Alkali = Salt + Water Acid +Metal = Salt + Hydrogen Acid + Carbonate = Salt + Water + Carbon Dioxide. NB An Alkali is a soluble Base.
Word equations for metal reactions?
metal + acid -> salt + water metal + oxygen -> metal oxide metal oxide + acid -> salt + water metal + water -> metal hydroxide + hydrogen Metal + Steam -> Metal Oxide + Hydrogen Metal + Acid -> Metal salt + Hydrogen
