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.
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.
Is magnesium metal and magnesium ribbon the same?
Yes. Magnesium ribbon is magnesium metal in the shape of a ribbon.
What is the number of moles of magnesium in a strip of magnesium with a mass of 0.1126g?
To find the number of moles of magnesium, we first need to calculate the molar mass of magnesium, which is 24.305 g/mol. Next, we convert the mass of the strip to moles using the formula moles = mass/molar mass. Plugging in the values, the number of moles of magnesium in the strip is 0.00463 moles.
What is a balanced chemical equation for magnesium strip and KCl?
The balanced chemical equation for magnesium strip reacting with KCl is: 2Mg(s) + 2KCl(aq) → 2K(s) + MgCl2(aq)
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 coating on a magnesium strip?
Magnesium oxide. It's produced by magnesium reacting with oxygen.
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.
Why dies a bimetallic strip when it is heated?
A bimetallic strip bends when heated because the two metals it is made of have different coefficients of thermal expansion. As the strip is heated, one metal expands more than the other, causing the strip to curve.
What happens when bimetallic strip is heated?
The bimetallic strip bends.
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.
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.
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.
Does the bimetallic strip bend when heated?
yes
Is magnesium metal and magnesium ribbon the same?
Yes. Magnesium ribbon is magnesium metal in the shape of a ribbon.
What changes takes place when bimetallic strip is heated?
actually what happen is that the strip is curved to the outside
Why is the magnesium strip polished before weighing?
The magnesium strip is polished before weighing to remove any surface impurities, such as dirt or oxidation, that could affect the accuracy of the measurement. By ensuring the strip is clean and free of contaminants, the weight obtained will be more accurate and reliable.
