Describe the type of change underdone by hydrochloric acid and magnesium.Explain your answer?

Answer 1

When magnesium is subjected to reaction with hydrochloric acid it forms MgCl2 and hydrogen gas is generated as shown below :


Mg + 2HCl -------> MgCl2 +H2 ;
Here, chemical reaction is taking place ,hemce it is a chemical change.

Answer 2

while magnesium, Mg is poured into hydrochloric acid, HCl the products is magnesium chloride, MgCl and hydrogen gasoline, H2 is launched. The commentary is effervescence take place and the magnesium, Mg strip will dissolved. The hydrogen ions in HCl is displace by using Mg because of the fact Mg is greater electropositivity than H. while effervescence take place this teach that a gasoline is being produce. while try with burning splinter, 'pop' sound could be heard. This teach the gasoline is hydrogen gasoline, H2

Answer 3

Single displacement via oxidation-reduction.

Mg + 2 HCl ---> MgCl2 + H2
