Question

Q7. Metals react with acids to
produce
Salt and water
Ο Ο Ο
Bases and Salt
O Hydrogen gas and Salt​

Answer 1

Answer:

Hydrogen Gas

Explanation:

Metals readily react with acid and produce hydrogen gas which burns with a pop sound. Metals are placed above hydrogen in reactivity series and displace during a reaction with an acid. As acids have a property of giving H +

ions. A resultant is formed with the release of hydrogen gas.

Answer 2

Answer:

hii

Explanation:

Hydrogen gas is not evolved when a metal reacts with dilute nitric acid because nitric acid is a strong oxidizing agent. So, as soon as hydrogen gas is formed in the reaction between a metal and dilute nitric acid, the nitric acid oxidizes this hydrogen to water. Very dilute nitric acid however, reacts with magnesium and manganese to evolve hydrogen gas.
