The balanced net ionic equation includes only species that are involved in the reaction. It can be found by removing ions that occur on both the reactant and product side of the complete ionic equation. Zn(s) + 2H+(aq) = H2(g) + Zn2+(aq) ...
Reaction Information Disclaimer Word Equation Dichromium Trioxide + Hydrogen Chloride + Zinc = Chromous Chloride + Zinc Chloride + Water One mole of Dichromium Trioxide [Cr2O3], six moles of Hydrogen Chloride [HCl] and one mole of Zinc [Zn] react to form two moles of...
In an experiment, 2 mol of Pb (NO3) 2 and 3 mol of NaI are mixed and the reaction represented by the balanced equation occurs: Pb (NO3) 2 + 2 NaI → PbI2 + 2 NaNO3 The solid produced is separated from the solution, while more ...
This investigation intends to explore the effects that the concentration of reactants has on the rateof a reaction between zinc and hydrochloric acid. Solid zinc will be placed in varyingconcentrations of hydrochloric acid solution, and the rate of disappearance of the acid will bemonitored and ...

Zn+2HC→ZnCl2+H2? Limiting reagentThe amount of product obtained in a reaction, is always determined by the amount of reactant that is completely consumed in the course of the reaction. This reagent is called the Limiting reagent. Answer and Explanatio...
The Al foil for high voltage Al electrolytic capacitor usage was immersed in 5.0% NaOH solution containing trace amount of Zn2+ and Zn was chemically plated on its surface through an immersion–reduction reaction. Such Zn-deposited Al foil was quickly transferred into HCl–H2SO4 solution for DC...
A precipitation reaction is a type of reaction that occurs when two ions react and form an insoluble salt. This type of reaction is usually a double displacement reaction in which two reactants exchange ions, forming new compounds. Usually, an insoluble salt forms and pr...
