Calculate the amount and mass of starting substances ‚If 10 grams of salt were obtained by their interaction. The reaction equation has the following form: Zn+2HCl -> ZnCl(2)+H(2)

mass Zn : 4.77 g

mass HCl : 5.32 g

The reaction equation is the chemical formula of reagents and product substances

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
