How do show that adding acid to the magnesium ribbon resulted in a chemical change?
Adding acid to magnesium ribbon results in a chemical change because it produces hydrogen gas and magnesium ions through a reaction. This change can be observed by the formation of bubbles (hydrogen gas) and the dissolution of the magnesium ribbon. Unlike physical changes, the original substances (magnesium and acid) are transformed into new products with different chemical properties. The reaction can be represented by the equation: Mg + 2HCl → MgCl₂ + H₂.
Can you reverse the chemical change of hydrochloric acid and magnesium?
The reaction between hydrochloric acid (HCl) and magnesium (Mg) forms magnesium chloride (MgCl2) and hydrogen gas (H2), which is a chemical change. To reverse this reaction, you would need to separate the magnesium chloride back into its component elements and then convert the hydrogen gas back to magnesium and hydrochloric acid, which is not practical or feasible.
What type of energy change associated with chemical reaction between magnesium and hydrochloric acid?
This reaction is exothermic.
Is adding white sugar to a clear acid a chemical change?
The sugar might dissolve in the acid and get added to the solution.
Is addition of iron to dil . acid a physical change or chemical change?
Adding water (which is not a reactant) is a physical process.
Is adding HCI to Mg a chemical change?
Yes. Magnesium metal reacts in hydrochloric acid to form magnesium chloride and hydrogen gas.
Is a magnesium ribbon fizzing in acid a physical change or chemical?
The reaction of a magnesium ribbon fizzing in acid is a chemical change. This is because new substances are formed during the reaction as the magnesium reacts with the acid to produce magnesium ions and hydrogen gas.
Is adding HCl to Mg physical change?
No, adding hydrochloric acid (HCl) to magnesium (Mg) and observing the resulting chemical reaction is a chemical change, not a physical change. The reaction produces hydrogen gas and magnesium chloride, with new substances formed.
Is adding HCl to Mg and physical or chemical change?
Adding Hydrochloric acid to magnesium induces a chemical change, according to the reaction: Mg(s) + 2HCl(aq) > MgCl2(aq) + H2(g)
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.
Is adding HCl to Mg a physical or chemical change?
Adding HCl to Mg would result in a chemical change. The reaction between hydrochloric acid (HCl) and magnesium (Mg) produces hydrogen gas (H2) and magnesium chloride (MgCl2), which are new substances formed by a rearrangement of atoms. This is a chemical change because the composition of the substances involved is altered.
Is mixing magnesium and hydrochloric acid a chemical change?
Because you change the composition of the original matter. It is no longer in its original state. Chemical Change- Change in composition; burning, crushing, etc. physical change- changing state, but substance's composition stays same; freezing, boiling, etc
Can you reverse the chemical change of hydrochloric acid and magnesium?
The reaction between hydrochloric acid (HCl) and magnesium (Mg) forms magnesium chloride (MgCl2) and hydrogen gas (H2), which is a chemical change. To reverse this reaction, you would need to separate the magnesium chloride back into its component elements and then convert the hydrogen gas back to magnesium and hydrochloric acid, which is not practical or feasible.
What is the chemical equation or magnesium and hydrochloric acid?
magnesium + hydrochloric acid = magnesium chloride + water
Is adding HCl to Mg a physical change?
No, adding hydrochloric acid (HCl) to magnesium (Mg) and observing the formation of magnesium chloride (MgCl2) is a chemical change because it involves the formation of new chemical substances with different properties.
