Co2 and Fe are the products the other two are reactants.
One mole (abbreviated mol) is equal to 6.022×1023 molecular entities (Avogadro's number), and each element has a different molar mass depending on the weight of 6.022×1023 of its atoms (1 mole). The molar mass of any element can be determined by finding the atomic mass of the element on the periodic table.
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)
B would probably be the better choice but A is also partially correct I would go with (B) though.
