Answer:
D.) 2 H₂ + O₂ -----> 2 H₂O
Explanation:
An equation is balanced when there is an equal amount of each element on both sides of the reaction. If these amounts are unequal, coefficients can be added to modify the amount of particular molecules.
A.) Not balanced
2 H₂ + 2 O₂ -----> H₂O
<u>Reactants</u>: 4 hydrogen, 4 oxygen
<u>Products</u>: 2 hydrogen, 1 oxygen
B.) Not balanced
2 H₂ + 2 O₂ -----> 2 H₂O
<u>Reactants</u>: 4 hydrogen, 4 oxygen
<u>Products</u>: 4 hydrogen, 2 oxygen
C.) Not balanced
H₂ + O₂ -----> H₂O
<u>Reactants</u>: 2 hydrogen, 2 oxygen
<u>Products</u>: 2 hydrogen, 1 oxygen
D.) Balanced
2 H₂ + O₂ -----> 2 H₂O
<u>Reactants</u>: 4 hydrogen, 2 oxygen
<u>Products</u>: 4 hydrogen, 2 oxygen
I don't know exactly what you are learning, but i know that chemistry involves the practice of mixing chemicals together to see what kind of reaction they make, if they make a reaction at all.
