5 g of potassium oxalate react to produce 0.03 moles of calcium oxalate.
Calcium oxalate (CaC₂O₄) is obtained by the reaction of 5 g of potassium oxalate (K₂C₂O₄).
We can calculate the moles of CaC₂O₄ obtained considering the following relationships.
- The molar mass of K₂C₂O₄ is 184.24 g/mol.
- The mole ratio of K₂C₂O₄ to CaC₂O₄ is 2:1.

When placed inside of a magnetic field, the magnetic field that electrons generate aligns in the opposite direction of the applied magnetic field.
Also, someone who is very popular and attracts people has a charming personality. A powerful speaker that attracts many fans has an engaging way of speaking. A magnetic person is attracted to you as if by a magical magnetism. Both meanings of magnetic have to do with the force of attraction. Only ferromagnetic materials such as iron, cobalt and nickel are attracted to magnetic fields strong enough to be considered truly magnetic.
All magnetic fields contain energy, also called magnetic energy. In physics, it is a constant. Magnetic energy is a form of energy from moving charge carriers (electrons) because magnetic fields are generated by electric currents.
