Is the equation #HNO_3(aq) + KOH(aq)->KNO_3(aq) + H_2O(l)# balanced?
The equation is balanced.
You can determine whether a chemical equation is balanced by counting the moles of each element present on each side. If the number of each type of atom is the same on both sides, the equation is balanced.
Given the chemical equation
We can see that on the left-hand side of the equation, there are two moles of hydrogen (H), one mole of nitrogen (N), one mole of potassium (K), and four moles of oxygen.
On the right-hand side, there are four moles of oxygen, two moles of hydrogen, one mole of potassium, and one mole of nitrogen.
Because both sides of the equation have equal amounts of each type of atom, it is a balanced equation.
