Write a balanced equation to show what happens when strontium oxide dissolves in water.
A
Sr2O3(s) + 3 H2O(l) → 2 Sr(OH)3(aq)
B
SrO(s) + H2O(l) → Sr(OH)2(aq)
C
SrO2(s) + 2 H2O(l) → Sr(OH)4(aq)
D
Sr2O(s) + H2O(l) → 2 SrOH(aq)
Verified step by step guidance1
Identify the correct formula for strontium oxide. The given formula Sr2O3 is incorrect. The correct formula for strontium oxide is SrO.
Write the unbalanced chemical equation for the dissolution of strontium oxide in water: SrO(s) + H2O(l) → Sr(OH)2(aq).
Check the balance of atoms on both sides of the equation. Ensure that the number of each type of atom is the same on both sides.
Balance the equation by adjusting coefficients if necessary. In this case, the equation SrO(s) + H2O(l) → Sr(OH)2(aq) is already balanced.
Verify the physical states of the reactants and products: SrO is a solid (s), H2O is a liquid (l), and Sr(OH)2 is aqueous (aq), indicating it is dissolved in water.
