Write balanced complete ionic equation for the reaction cas(aq)+cucl2(aq)→cus(s)+cacl2(aq)
2 answers:
<u>Answer:</u> The given equation is already balanced.
<u>Explanation:</u>
A balanced chemical reaction is defined as the reaction in which total mass on the reactant side is equal to the total mass on the product side.
These equations follow Law of Conservation of Mass. The mass remains conserved in a chemical reaction.
For the given chemical equation:
On the reactant side:
On product side:
As, the mass on reactant side is equal to the mass on product side. Hence, the equation is a balanced chemical equation.

Answer: 250 ml of stock solution with molarity of 12.0 M is measured using a pipette and 250 ml of water is added to volumetric flask of 500 ml to make the final volume of 500 ml.
Explanation:
According to the dilution law,
where,
= concentration of stock solution = 12.0 M
= volume of stock solution = ?
= concentration of diluted solution= 6.00 M
= volume of diluted acid solution = 500 ml
Putting in the values we get:
Thus 250 ml of stock solution with molarity of 12.0 M is measured using a pipette and 250 ml of water is added to volumetric flask of 500 ml to make the final volume of 500 ml.
