If 6.5 L of water is added to 4.5 L of a 2.8 M Ca(OH)2 solution, what is the molarity of the new solution?

Find moles of Ca(OH)2 first:

moles = 2.8 x 4.5 = 12.6

Now,
After addition, new volume = 6.5 + 4.5 = 11.0

So, new molarity = 12.6 / 11 = 1.145

Do chemical equations with no reaction still have to be balanced

dangina [55]

Answer:

The same number of atoms of each element must appear on both sides of a chemical equation. However, simply writing down the chemical formulas of reactants and products does not always result in equal numbers of atoms. You have to balance the equation to make the number of atoms equal on each side of an equation.
