(a)
Interpretation:
The reactants and product should be identified given the reaction.
Concept Introduction:
Chemical equation is a short representation of the
Physical change the substance is does not change it jest appearance only changed while the new substance is not created.in chemical changes where there is a chemical reaction a new substance formed and energy is either given off or absorbed.
(b)
Interpretation:
Interpretation:
Which substances are chemical compound and elements should be identified in the given reaction.
Concept Introduction:
Pure substance: The substance that has a uniform (or) homogeneous chemical composition throughout.
Mixture: It is blend of two or more substance, each of which retains its chemical identically.
Chemical formula: It is one elements combine to from a chemical compound, symbol are combined to produce chemical formula which use subscript to identify how many od atoms of each element are in a given chemical compound. For example the formula (H2O) represents water it contains two hydrogen atoms combined with one oxygen atoms.
