Question

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical

equation:
()Li2O + ((*)H20 - ( LiOH

Answer 1

1 Li2O + 1 H2O → 2 LiOH

Step-by-step explanation:

The unbalanced equation is:

Li2O + H2O → LiOH

Balanced, it should be:

Li2O + H2O → 2 LiOH

Let's verify the balance:

- Lithium (Li) atoms: There are 2 lithium atoms in one molecule of Li2O, and since we produce 2 LiOH molecules, each having 1 lithium atom, we also have 2 lithium atoms on the product side. (2 Li atoms on both sides)

- Oxygen (O) atoms: There is 1 oxygen atom in one molecule of Li2O, and 1 oxygen atom in one molecule of H2O on the reactant side for a total of 2 on the reactant side. On the product side, each LiOH molecule contains 1 oxygen atom, and since we form 2 LiOH molecules, there are also 2 oxygen atoms on the product side. (2 O atoms on both sides)

- Hydrogen (H) atoms: There are 2 hydrogen atoms in one molecule of H2O on the reactant side, and since we produce 2 LiOH molecules, each with one hydrogen atom, we also have 2 hydrogen atoms on the product side. (2 H atoms on both sides)

So the correct balanced equation, with coefficients, is:

1 Li2O + 1 H2O → 2 LiOH

This equation is now balanced in terms of atoms on both sides for lithium, oxygen, and hydrogen, and it adheres to the law of conservation of mass.
