In which chemical equation is the number of atoms in the reactants the same as the number of atoms in the products?(1 point)
Responses
Li2CO3 → LiO + CO2
Li 2 CO 3 → LiO + CO 2
CO2 + H2O → CH2OH + O2
CO 2 + H 2 O → CH 2 OH + O 2
Zn + 2HCl → H2 + ZnCl2
Zn + 2HCl → H 2 + ZnCl 2
CH4 + O2 → CO2 + 2H2O
The chemical equation in which the number of atoms in the reactants is the same as the number of atoms in the products is:
Zn + 2HCl → H2 + ZnCl2
The chemical equation in which the number of atoms in the reactants is the same as the number of atoms in the products is:
Zn + 2HCl → H2 + ZnCl2
The chemical equation in which the number of atoms in the reactants is the same as the number of atoms in the products is:
2Zn + 4HCl → 2H2 + 2ZnCl2
To determine the number of atoms in the reactants and products, we need to count the atoms of each element on both sides of the equation.
In this equation, we have:
- 2 atoms of Zinc (Zn) on both sides
- 4 atoms of Hydrogen (H) on both sides
- 2 atoms of Chlorine (Cl) on both sides
Therefore, the equation 2Zn + 4HCl → 2H2 + 2ZnCl2 satisfies the condition that the number of atoms in the reactants is the same as the number of atoms in the products.
