Copper oxide reacts with hydrochloric acid to produce copper chloride and water.
So the basic equation that illustrates this reaction is:
CuO + HCl ......> CuCl2 + H2O
Now, we need to balance this equation:
the number of copper and oxygen moles are balanced.
For each of hydrogen and chlorine, we have one mole as a reactant and two moles as product.
Therefore, to balance this, we will add an extra mole of HCl in the reactants.
Based on this, the final balanced equation would be:
CuO + 2HCl ................> CuCl2 + H2O
It is important because even if you believe your new product idea is a guaranteed winner, testing the market before you launch can help you tweak what you’re selling or how you’re selling it, helping you maximize your profits. Product marketing tests let you evaluate multiple aspects of your business strategy before you commit your entire budget.
