The reaction of potassium (K) with hydrochloric acid (HCl) would result in a chemical change.
2K(s) + 2HCl ==> 2KCl + H2(g). This is a chemical change because K has been converted to a new chemical, KCl, and H in HCl has been converted to H2 gas.

When magnesium and hydrochloric acid react what do they produce?

The reaction between magnesium and hydrochloric acid produces magnesium chloride and hydrogen gas. The balanced chemical equation is: Mg + 2HCl → MgCl2 + H2.


Word equation for hydrochloric acid and magnesium?

Mg + 2HCl → MgCl2 + H2 magnesium+Hydrochloric acid→magnesium chloride+water (H2O)


What happens to particles when magnesium and hydrochloric acid react together?

When magnesium reacts with hydrochloric acid, it forms magnesium chloride and hydrogen gas. The magnesium metal reacts with the hydrochloric acid to produce magnesium chloride, a salt, and hydrogen gas is released as a byproduct.


When a piece of magnesium is added to dilute hydrochloric acid occurs and hydrogen gas is released from the mixtureThe fizzing is evidence that has occured between magnesium and hydrochloric acid is?

The fizzing observed is indicative of a chemical reaction occurring between magnesium and hydrochloric acid. Specifically, the magnesium is reacting with the hydrochloric acid to produce magnesium chloride and hydrogen gas. The release of hydrogen gas is responsible for the bubbling or fizzing seen during the reaction.


What does magnesium oxide plus hyrdrochloric acid make?

hydrochloric acid + magnesium => magnesium chloride + hydrogen 2HCl + Mg => MgCl2 + H2


What happens if you mix magnesium with hydrochloric acid?

When magnesium is mixed with hydrochloric acid, a chemical reaction occurs which releases hydrogen gas and forms magnesium chloride. This reaction is exothermic, meaning it releases heat. It is important to handle this reaction carefully as it can be vigorous and produce flammable hydrogen gas.


What does hydrochloric acid and magnesium produce?

When hydrochloric acid reacts with magnesium, it produces magnesium chloride and hydrogen gas as the products. This is a single replacement reaction where the more reactive magnesium displaces hydrogen in the acid to form the products.


What would hydrochloric acid do if it come into contact with a metal such as magnesium?

Hydrochloric acid would react with the metal magnesium to produce magnesium chloride and hydrogen gas. This reaction involves the acid dissolving the metal to form a salt and releasing hydrogen gas as a byproduct.


Mixing magnesium and the product of burning magnesium with hydrochloric acid is it a physical or chemical change?

Mixing magnesium and the product of burning magnesium with hydrochloric acid would lead to a chemical change. The reaction between magnesium oxide (product of burning magnesium) and hydrochloric acid would produce magnesium chloride and water, showing a chemical reaction taking place due to the formation of new substances with different properties.


What is the reaction between hydrochloric acid and magnesium?

These two substances readily react to produce magnesium chloride and hydrogen gas, The reaction equation is Mg(s)+ 2HCl(aq) = MgCl2(aq) + H2(g)


Does mixing magnesium and hydraulic acid make energy?

No, mixing magnesium and hydrochloric acid does not directly produce energy. The reaction between magnesium and hydrochloric acid does release energy in the form of heat and hydrogen gas, but it is not considered a significant energy source.


What happens to the magnesium atoms when you mix it with dilute hydrochloric acid?

When magnesium reacts with dilute hydrochloric acid, it produces magnesium chloride and hydrogen gas. The magnesium atoms lose electrons to form magnesium ions, while hydrogen ions from the acid gain electrons to form hydrogen gas.
