Why copper wire is appropriate choice to secure magnesium strip?
Copper wire is a good choice to secure a magnesium strip because copper does not react with magnesium, so it will not interfere with the chemical properties of the magnesium strip. Additionally, copper is malleable and ductile, making it easy to wrap around and secure the magnesium strip in place.
How and why does the mass of a magnesium strip change when it is heated strongly in air?
When a magnesium strip is heated strongly in air, it undergoes a chemical reaction called oxidation. Magnesium reacts with oxygen in the air to form magnesium oxide. The mass of the strip increases because magnesium combines with oxygen atoms from the air to form a heavier compound (magnesium oxide).
What is a reagent strip?
The reagent strip is a strip of paper impregnated with a specific chemical reagent for a chemical determination.
Balanced chemical equation for A nickel strip places in coppper 2 sulfate becomes plated in copper?
The net ionic equation for this process is: Ni(s) + Cu(+2)(aq) --> Ni(+2)(aq) + Cu(s). This is an oxidation-reduction reaction, where nickel is oxidized and copper is reduced.
Does the coating on a magnesium strip change the mass of magnesium oxide?
Yes, the coating on a magnesium strip can affect the mass of magnesium oxide because the coating can add additional mass to the strip. When the magnesium reacts with oxygen to form magnesium oxide, the mass of the coating is also included in the total mass of the resulting compound.
Word equation for hydrochloric acid and magnesium?
Mg + 2HCl → MgCl2 + H2 magnesium+Hydrochloric acid→magnesium chloride+water (H2O)
What is the chemical composition of magnesium ribbon?
that is magnesium itself, in the form of a ribbon
Does the magnesium strip resemble Mg?
Yes, a magnesium strip is made of elemental magnesium (Mg). It is typically a thin piece of solid magnesium metal that can be used for different chemical reactions or experiments.
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 a strip of magnesium is added to a solution of silver nitrate?
The balanced chemical reaction is: Mg(s) + 2AgNO3(aq) → Mg(NO3)2(aq) + 2Ag(s) This reaction produces silver metal precipitate and magnesium nitrate in solution.

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)
What is the coating on a magnesium strip?
Magnesium oxide. It's produced by magnesium reacting with oxygen.
Does a magnesium metal strip rust when put in hydrochloric acid?
No, magnesium does not rust like iron does when exposed to acids. Instead, magnesium reacts with hydrochloric acid to form magnesium chloride and hydrogen gas, producing bubbles as a result of the chemical reaction.
Was a strip of magnesium metal into a solution of copper sulfate a chemical change?
Yes. The magnesium metal replaces the copper in the copper sulfate. This is a single replacement or single displacement reaction.
What is a reagent strip?
The reagent strip is a strip of paper impregnated with a specific chemical reagent for a chemical determination.
