Concept explainers
(a)
Interpretation:
The chemical equation for the displacement of hydrogen gas from HCl(aq) by Al(s) should be determined.
Concept introduction:
A chemical equation is the representation of a
All molecules must be written with their physical state as sub script such as (s) for solid, (l) for liquid, (g) for gas and (aq) for aqueous. A balance chemical equation is the chemical equation in which all the atoms at both sides of the equation are same.
(b)
Interpretation:
The chemical equation for the reforming of propane gas with steam should be determined.
Concept introduction:
A chemical equation is the representation of a chemical reaction with the complete information of reactant and product molecules. Here both types of molecules must be written as their chemical symbols separated by the single headed arrow. If the reaction is at the equilibrium position, it must be an equilibrium sign (
All molecules must be written with their physical state as sub script such as (s) for solid, (l) for liquid, (g) for gas and (aq) for aqueous. A balance chemical equation is the chemical equation in which all the atoms at both sides of the equation are same.
(c)
Interpretation:
The chemical equation for the reduction of MnO2 to H2 and Mn should be determined.
