what would happen when metal reacts with water and acid explain with example acc to 5 mark for class 10
Answers
Answer:
We first learned that highly reactive metals react with dilute acids, water, and oxygen. Evidence of the reaction with a dilute acid is the formation of hydrogen gas bubbles. These reactions involve the transfer of electrons from the metal to the hydrogen atoms.
When a metal reacts with dilute acid, salts are formed. During this reaction hydrogen gas is evolved. In other words, when a metal is added to dilute acids, salt and hydrogen gas are formed. Sulfate salts and chloride salts are formed when metals react with dilute sulfuric acid and hydrochloric acid.
Answer:
It reacts with hot water to form magnesium hydroxide and hydrogen. It also starts floating due to the bubbles of hydrogen gas sticking to its surface. Metals like aluminium, iron and zinc do not react either with cold or hot water. ... You have already learnt that metals react with acids to give a salt and hydrogen gas.
