10) Is the chemical equation balanced?
2 Al + Fe2O3
2Fe + Al2O3​

Yes , the equation is balanced.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The given chemical equation is:

As the number of atoms on reactant side is equal to the number of atoms on product side, the equation is balanced.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
