Respuesta :
Balanced formation equation at standard conditions Ca (s) + Cl₂ (g) → CaCl₂ (s) [ΔH° (Ca (s)) = 0 and ΔH° (Cl₂ (g)) = 0].
What is Chemical Reaction ?
A chemical reaction is a process in which chemical bonds between atoms to break and reorganize, to form a other new substances.
The chemical reaction for CaCl₂ is
Ca (s) + Cl₂ (g) → CaCl₂ (s)
Reactant Side Product Side
Ca = 1 Ca = 1
Cl = 2 Cl = 2
In the reactant side there are 1 Ca atoms and in the product side also 1 Ca atoms. In the reactant side there are 2 Cl atoms and in the product side also 2 Cl atoms
So, the above equation is balanced.
Now, write the balanced formation equation at standard conditions
Ca (s) + Cl₂ (g) → CaCl₂ (s) [ΔH° (Ca (s)) = 0 and ΔH° (Cl₂ (g)) = 0]
Thus from the above conclusion we can say that Balanced formation equation at standard conditions Ca (s) + Cl₂ (g) → CaCl₂ (s) [ΔH° (Ca (s)) = 0 and ΔH° (Cl₂ (g)) = 0]
