Question
Which of the following is the balanced chemical equation for the reaction of lithium with water:Group of answer choicesNo reaction occurs2Li(s) + 2H2O(l) --> 2Li+(aq) + 2OH –(aq) + H2(g)2Li(s) + H2O(l) --> 2Li+(aq) + 2OH –(aq) + H2(g)2Li(s) + 2H2O(l) --> 2Li+(aq) + 4OH –(aq)
Solution
The balanced chemical equation for the reaction of lithium with water is:
2Li(s) + 2H2O(l) --> 2Li+(aq) + 2OH –(aq) + H2(g)
Here's the step by step process:
-
Identify the reactants and products: The reactants are lithium (Li) and water (H2O). The products are lithium ions (Li+), hydroxide ions (OH-) and hydrogen gas (H2).
-
Balance the equation: The law of conservation of mass states that matter cannot be created or destroyed. Therefore, the number of atoms of each element on the reactant side must equal the number of atoms of the same element on the product side.
On the reactant side, we have 2 lithium atoms, 4 hydrogen atoms, and 2 oxygen atoms. On the product side, we have 2 lithium ions, 2 hydroxide ions (which gives us 2 oxygen atoms and 2 hydrogen atoms), and 1 molecule of hydrogen gas (which gives us 2 hydrogen atoms).
So, the number of atoms for each element is balanced on both sides of the equation.
