Why might magnesium metal rather than copper metal be used to study the effect of concentration of hydrochloric acid on rates of reactions?

Magnesium powder has a larger surface area, depending on quantity it may react too quickly, whereas with a ribbon the temperature change is slower and therefore easier to record and monitor the rate of reaction.

Copper is relatively uncreative and so will not react appreciably.

What metal is most reactive with hydrochloric acid out of magnesium and copper?
Magnesium
What would happen if you diluted magnesium and copper with hydrochloric acid?
Magnesium chloride and copper chloride are formed in solution and hydrogen is released.
What catalysts to use for reaction between magnesium and hydrochloric acid?
I think it's copper sulphate
What does magnesium and copper oxide make?
Magnesium + copper oxide --> magnesium oxide + copper
Suggest why magnesium chloride can be made by mixing magnesium with hydrochloric acid but copper chloride cannot be made by mixing copper with hydrochloric acid?
Copper is an inert metal and below hydrogen in electro chemical series therefore can not displaced hydrogen from acids so copper can not be converted directly to salts by reacting with acids, however concentrated sulphuric acid reacts with copper on heating in presence of atmospheric oxygen forming the copper sulphate, chlorides and other salts are prepared from its sulphate salt.
What metal is most reactive with hydrochloric acid out of magnesium and copper?
Magnesium
The differences in the reactions of potassium magnesium and copper with water?
the diffrences in reaction of potassium, magnesium and copper
What would happen if you diluted magnesium and copper with hydrochloric acid?
Magnesium chloride and copper chloride are formed in solution and hydrogen is released.
What are some metal reactions?
copper sulphate plus hydrochloric acid
Why copper wire is appropriate choice to secure magnesium strip?
Copper can't be dessolved by the hydrochloric acid.
What catalysts to use for reaction between magnesium and hydrochloric acid?
I think it's copper sulphate
What do you get when you mix copper carbonate and hydrocloric acid?
Most probably copper chloride and carbon dioxide, if the concentration of hydrochloric acid is high enough.
What does magnesium and copper oxide make?
Magnesium + copper oxide --> magnesium oxide + copper
Suggest why magnesium chloride can be made by mixing magnesium with hydrochloric acid but copper chloride cannot be made by mixing copper with hydrochloric acid?

Why is magnesium most reactive if it reacts with hydrochloric acid among lead copper silver zinc iron?
the chemical compound will ignite causing PB/LED
Why does magnesium and copper sulfate react?
Magnesium is more reactive than copper, so it will displace (swap places) with the copper forming magnesium sulphate and copper.
Why does copper sulfate solution turn clear and magnesium develop a copper coating?
Redox! The magnesium is reducing the copper while the copper is oxidizing the magnesium. In other words, magnesium is giving electrons to the copper to bring the copper back to its metallic form while the magnesium is leaving the metal to be part of the solution as magnesium sulfate, which is colorless.
