What type of energy change associated with chemical reaction between magnesium and hydrochloric acid?
This reaction is exothermic.
Is adding magnesium and heat chemical or physical change?
Heating magnesium is a physical process.But the reaction of magnesium with oxygen at high temperature is a chemical process.
Is magnesium is a chemical reaction?
Magnesium is a chemical element, a solid metal not a reaction.
Why is putting magnesium in water a chemical change?
Magnesium is highly reactive to water because of the atom's electron arrangement. The products of the reaction are, heat, light, and gas, which are all indicators that they had undergone a chemical reaction.
When magnesium ribbon is ignited it gives off a white fume of magnesium oxide. What is this type of reaction?
The reaction is 2Mg + O2 ----> 2MgO Mainly it is a Composition reaction (also called as combination or syntesis reaction). But also catogrised in redox reaction & combution reaction.
What type of energy change associated with chemical reaction between magnesium and hydrochloric acid?
This reaction is exothermic.
Is magnesium burning a physical change?
This is a chemical change, like any other burning reaction: magnesium is turned into magnesium oxide by burning reaction with oxygen (from air). 2Mg + O2 --> 2MgO
Is burning magnesium a physical change?

What type of chemical reaction takes place when magnesium wire is heated?
When magnesium metal wire is heated in open air, an oxidation-reduction reaction takes place between the magnesium and the oxygen in the air. The magnesium is oxidized as the oxygen is reduced. The product of this reaction is magnesium oxide, MgO. Note that this reaction can also be deemed a combustion reaction, which is a specific type of redox reaction which involves the production of heat and sometimes light.
When magnesium combine with oxygen to form magnesium oxide what type of reaction is form?
combination
If you melt magnesium metal is it a chemical change?
Yes, the combustion of magnesium, or anything else for that matter, represents a chemical change. For magnesium, the combustion reaction results in the loss of magnesium and the production of magnesium oxide. Clearly a chemical change.
Is adding magnesium and heat chemical or physical change?
Heating magnesium is a physical process.But the reaction of magnesium with oxygen at high temperature is a chemical process.
When magnesium burns in air is it chemical or physical change?
Burning magnesium (or burning anything) can be described as a chemical reaction, or as a chemical change. It is not a property. However, the capacity of being able to burn, also known as flammability, is a chemical property.
Is burning a strip of magnesium ribbon a chemical or physical change?
This is a chemical change. The reaction is: Mg + O ---> MgO
Is mixing magnesium with oxygen a chemical reaction?
Yes. Because there is a chemical change
Why is the burning of magnesium considered a chemical change?
During burning magnesium is transformed in magnesium oxide - a chemical reaction:2 Mg + O2 = 2 MgO
What is the type of reaction for Mg ribbon burning in fire?
Magnesium is converted into Magnesium oxide. 2Mg + O2 -----> 2MgO
