The reaction is highly exothermic as heat energy is released from the system to the surroundings whereas in endothermic the heat is absorbed from the surroundings into the system and you can also observe or see the smoke coming out of the apparatus in which the reaction is occurring or taking place.Heat energy is being released in the form of smoke.Therefore the reaction is exothermic.

What would you see if a piece of magnesium ribbon reacts with dilute hydrocholric acid?
When a piece of magnesium ribbon reacts with dilute hydrochloric acid, you would observe effervescence (bubbling) as hydrogen gas is released. The magnesium ribbon would dissolve in the acid, producing magnesium chloride solution. The solution may also become warm due to the exothermic nature of the reaction.
Is burning a strip of magnesium ribbon a chemical or physical change?
Burning a strip of magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This reaction results in the formation of new substances with different properties than the original magnesium ribbon.
What is the balanced reaction when you place a small strip of magnesium ribbon into a flame?
The balanced reaction when magnesium ribbon reacts with oxygen in a flame is: 2 Mg(s) + O2(g) -> 2 MgO(s)
Is a magnesium ribbon a conductor?
Magnesium is a metal element. It has free electrons. So it is a good conductor.
Why should you not look at magnesium ribbon when it burns?
Looking at burning magnesium ribbon can cause damage to the eyes due to the intense UV light it emits. This can result in temporary or permanent vision impairment. It is important to wear proper eye protection when observing the burning of magnesium ribbon to avoid eye injury.
Sulfuric acid and magnesium ribbon endothermic or exothermic?
I don't know for sure, but it is probably exothermic. (PLEASE CORRECT ME!)
What type of reaction takes place when a magnesium ribbon is burnt in air?
The reaction that takes place when a magnesium ribbon is burnt in air is a combustion reaction. This reaction produces magnesium oxide as a product, and it is exothermic, releasing heat and light.
Why does magnesium ribbon increase the temperature of hydrochloric acid?
When magnesium ribbon is added to hydrochloric acid, a chemical reaction occurs that releases energy in the form of heat. This reaction produces magnesium chloride and hydrogen gas, which results in an increase in temperature of the solution.
What happens when you put magnesium ribbon in hydrochloric acid?
When magnesium ribbon is placed in hydrochloric acid, a chemical reaction occurs. The magnesium reacts with the hydrochloric acid to form magnesium chloride and hydrogen gas. This reaction is exothermic, meaning it releases heat energy.
Mg ribbon continuous to burn in presence of CO 2.why?
When magnesium ribbon burns in the presence of CO2, it forms magnesium oxide and carbon. The reaction is exothermic, releasing heat to sustain the burning of the magnesium ribbon. The CO2 supplies oxygen to support combustion.
What do you observe when magnesium ribbon is heated to form magnesium oxide?
When magnesium ribbon is heated, it reacts with oxygen in the air to form a white powder, which is magnesium oxide. This reaction is exothermic, producing a bright white light and a release of heat. The magnesium ribbon disappears as it combines with oxygen to form the solid magnesium oxide.
Is Magnesium ribbon burns leaving white ash?
Yes, when magnesium ribbon burns, it reacts with oxygen in the air to produce magnesium oxide, which appears as a white ash. This combustion is highly exothermic, resulting in a bright white flame. The white ash formed is primarily magnesium oxide, a powdery substance that can be seen after the reaction.
Does magnesium ribbon react with hydrocloric acid?
Yes, magnesium ribbon reacts with hydrochloric acid. When magnesium comes into contact with hydrochloric acid, it produces magnesium chloride and hydrogen gas. The reaction is exothermic and can be represented by the equation: ( \text{Mg} + 2\text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2 \uparrow ). This reaction typically results in the evolution of bubbles due to the release of hydrogen gas.
Does magnesium ribbon in copper sulfate solution produce a gas?
Yes, when magnesium ribbon is added to copper sulfate solution, a reaction takes place where magnesium displaces copper from the solution. This reaction produces magnesium sulfate and elemental copper. No gas is formed during this reaction.
What is the type of reaction for Mg ribbon burning in fire?
The reaction of Mg ribbon burning in fire is a combustion reaction. In this reaction, magnesium reacts with oxygen to form magnesium oxide along with the release of light and heat energy.
When a piece of magnesium ribbon is placed into beaker containing hydrochloride acid bubbling is of served a chemical change?
When magnesium ribbon is placed in hydrochloric acid, a chemical reaction occurs, resulting in the formation of magnesium chloride and hydrogen gas. The bubbling observed is due to the release of hydrogen gas as the magnesium reacts with the acid. This reaction is characterized by the magnesium dissolving and the solution becoming warmer, indicating an exothermic process. Overall, the visible bubbling and changes in the solution confirm a chemical change has taken place.
Does Magnesium Ribbon evaporate?
Magnesium ribbon does not evaporate in the traditional sense. When heated to high temperatures, magnesium undergoes a chemical reaction known as oxidation, where it combines with oxygen from the air to form magnesium oxide. This process is not considered evaporation.
