Which of the following is not a balanced chemical equation?a)Zn(s)+H2S...
Explanation:
A balanced chemical equation has an equal number of atoms of each element on both sides of the equation. It also follows the law of conservation of mass, which states that the total mass of reactants equals the total mass of products.
Let us analyze each option to determine which is not a balanced chemical equation:
a) Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g)
- This is a balanced chemical equation because there is an equal number of atoms of each element on both sides of the equation: 1 zinc, 1 sulfur, 4 oxygen, 2 hydrogen.
b) Fe(s) + Cl2(g) → FeCl2(s)
- This is not a balanced chemical equation because there are more atoms of chlorine on the reactant side than the product side: 2 chlorine atoms on the reactant side and only 1 chlorine atom on the product side.
c) Mg(s) + CuSO4(aq) → MgSO4(aq) + Cu(s)
- This is a balanced chemical equation because there is an equal number of atoms of each element on both sides of the equation: 1 magnesium, 1 copper, 4 oxygen, 2 sulfur.
d) Ca(OH)2(l) + CO2(g) → CaCO3(s) + H2O(l)
- This is a balanced chemical equation because there is an equal number of atoms of each element on both sides of the equation: 1 calcium, 1 carbon, 3 oxygen, 2 hydrogen.
Therefore, option b) Fe(s) + Cl2(g) → FeCl2(s) is not a balanced chemical equation because there are more atoms of chlorine on the reactant side than the product side.
