Explanation:
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)
<span>A dim white dwarf star, this is a star with a similar mass to earth. This star has no further fusion reactions at it's core. After this type of star has used up all of it's energy it will become a black dwarf star. Usually they are composed of oxygen and carbon. Sirius a and b are both white dwarf stars that orbit each other.</span>
