Which one of the following is an example of a balanced chemical reaction? a. 8HCl + 2KMnO4 → 3Cl2 + 2MnO2 + 4H2O + 2KCl.
b. 6HCl + 2KMnO4 → 2Cl2 + 2MnO2 + 4H2O + 2KCl.
c. 2HCl + 2KMnO4 → Cl2 + MnO2 + 2H2O + 2KCl.
d. HCl + KMnO4 → Cl2 + MnO2 + H2O + KCl.
e. HCl + KMnO4 → Cl2 + MnO2 + 2H2O + KCl.

Option a.

Explanation:

To determine which is a balanced chemical reaction, see the stoichiometry.

Stoichiometry coefficients are the numbers that appear before the compounds. These numbers indicate moles of substance.

Notice that the number of elements must be the same in both sides of the equation.

In this case, option a is the balanced chemical reaction.

8HCl + 2KMnO₄ → 3Cl₂ + 2MnO₂ + 4H₂O + 2KCl

8 moles of HCl react to 2 moles of potassium permanganate in order to produce 2 moles of magnessium dioxide, 3 moles of chlorine, 2 moles of potassium chloride and 4 moles of water.

8 H, 8 Cl, 2 K, 2 Mn and 8 O

c. 75.7

i think that is the right

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
