No it does not have a coefficient.
In a redox reaction an electron is lost by the reducing agent
Answer:
It's because it has 2 electrons on its outer ring
Explanation:
It has a -2 ion due to it having 2 more electrons than protons making it an overall negative. It's well known in chemistry that the first ring can only hold 2 electrons while the second and furthermore can hold up to 8. But what happens when you have 9? a new ring starts and it would only contain 1 electron.. In our case here it has 2 more electrons than protons and those 2 electrons are located on the outer ring
Answer:
MgCl₂(aq) + Al₂(CO₃)₂(aq) --> MgCO₃(s) + AlCl₃(aq)
Explanation:
Magnesium Chloride - MgCl₂
Aluminium Carbonate - Al₂(CO₃)₃
Magnesium carbonate - MgCO₃
Aluminium Chloride - AlCl₃
The equation of this reaction is given as;
MgCl₂(aq) + Al₂(CO₃)₃(aq) --> MgCO₃(s) + AlCl₃(aq)
