Alexxx [7]
Hydrophilic substances will dissolve better in water than hydrophobic substances. A substance that is hydrophilic is water loving or easily dissolved in water. Molecules of these substances form ionic bonds with the water molecules. Hydrophilic substances include alcohols. Hydrophobic substances repel water and do not mix.

Can someone explain how to do this?
Sidana [21]

Balanced equation :

3H₂+N₂⇒2NH₃

<h3>Further explanation</h3>

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product

3. Select the coefficient of the substance with the most complex chemical formula equal to 1

Unbalanced⇒the number of atoms from both sides (reactants and products) is not the same

H₂+N₂⇒NH₃

H=2(left), H=3(right)

N=2(left), N=1(right)

Balanced ⇒ the number of atoms from both sides (reactants and products) is equal

3H₂+N₂⇒2NH₃

H=3x2=6(left), H=2x3=6(right)

N=2(left), N=2x1=2(right)
