Q. Which metal is more reactive than copper?
Magnesium is more reactive than copper, so magnesium can displace copper from a copper sulfate solution to create magnesium sulfate.
Q. Which is more reactive and why Aluminium and copper?
Aluminium has more free electrons for reactions compared to copper with less free electrons.
Q. Is aluminum most reactive?
Aluminium does not react very well with the oxygen in the air but it is in fact quite a reactive metal. The reason it does not react is that is has already reacted, but the aluminium oxide has formed in a thin, tightly bonded layer that protects the aluminium foil from further attack.
Q. What happens when water touches aluminum?
What happens when water meets aluminium? Due to its highly negative redox potential, aluminium reacts with water to produce hydrogen gas according to the equation: 2Al + 3H2O → 3H2 + Al2O3. This chemical reaction may be of particular importance when it occurs between the strands of an aluminium conductor.
Q. What is more reactive calcium or lead?
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions ….The reactivity series.
| Element | Reaction with water |
|---|---|
| Calcium | More slowly |
Q. Which element is least reactive in oxygen?
Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. Noble gases are the least reactive of all elements. That’s because they have eight valence electrons, which fill their outer energy level.
Q. Which two families contain the most active metals?
The two most reactive families of elements are the halogens and the alkali metals.
Q. How do you know if a metal is active?
A metal is said to be an active metal when it reacts strongly and quickly with other elements due to the electrons in its structure and its ease of sharing the electrons with other elements. In chemistry, the periodic table of elements depicts all of the known elements.
Q. Which is more reactive copper or mercury?
The metals placed above hydrogen in the series can displace it from acids such as HCl and H2SO4 (since they are more reactive)….Long Tabular Form of the Reactivity Series.
| Reactivity Series of Metals | Ions Formed |
|---|---|
| Copper | Cu2+ |
| Tungsten | W3+ |
| Mercury | Hg2+ |
| Silver | Ag+ |
Q. Is sodium or copper more reactive?
Thus, Sodium is more reactive than copper.
Q. Why do electrons move from zinc to copper?
Voltaic Cells Zinc more readily loses electrons than copper, so placing zinc and copper metal in solutions of their salts can cause electrons to flow through an external wire which leads from the zinc to the copper. The zinc “half-reaction” is classified as oxidation since it loses electrons.
Q. Why Copper does not react with dilute HCl?
Yes, it is obvious that copper will not react with hydrochloric acid for the simple reason it’s below hydrogen in the reactivity series. So, copper cannot replace the hydrogen in HCl to form CuCl2 . Hence, when copper (Cu) reacts with hydrochloric acid (HCl) there will be no reaction.
