What is the balanced equation for fe+o2—-> fe3o4

The balanced chemical reaction is:

Explanation:

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

While balancing the chemical equation balance all the atoms of elements except oxygen atom which will be done in the last.

Step 1: Write three in front of iron;

Step 2: Now write two in front of oxygen gas;

The balanced chemical reaction is:

According to reaction, 3 moles of iron reacts with 2 moles of oxygen gas to give 1 mole of ferric oxide.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
