Newton’s universal law of gravitation states that all objects attract each other with a force -directly- proportional to the product of their masses and -inversely- proportional to the square of the distance between their centers. When considering objects on the surface of the Earth, the force is -away from directly-proportional to the product of the mass of the object and the -acceleration- due to -gravity-at the Earth’s surface. Since the Earth is -larger- than ant object under consideration, the object is drawn -toward- the Earth.

Write the balanced chemical equation for the extraction of iron in the thermite reaction.
blagie [28]

In the given chemical reaction iron is less electropositive metal and aluminum is more electropositive and behave as a reducing agent also.

<h3>What is electropositivity?</h3>

Electropositivity is the ability of an atom of donation or losing of electrons easily.

From the given chemical reaction it is clear that oxidation state of iron changes from +3 to 0 & of aluminum is from 0 to +3. So in the above chemical reaction aluminum is more electropositive than iron metal. And aluminum is behave as a reducing agent as it helps in the reduction process by providing electrons.

Hence aluminum is electropositive metal and reducing agent, iron is less electropositive.
