A(aq)+B(g)→C(s)+D(l)(1.1)
(1.1) A
(
aq
)
+B
(
g
)
→C
(
s
)
+D
(
l
)
In the above example, A
A
and B
B
, known as the reactants, reacted to form C
C
and D
D
, the products.
To write an accurate chemical equation, two things must occur:
Each product and reactant must be written using its chemical formula, e.g., H2
H
2
The number of atoms of each element must be equal on both sides of the equation. Coefficients are used in front of the chemical formulas in order to help balance the number of atoms, e.g.,

a chemical change is represented by a chemical equation
example
Zn + 2HCL = ZnCl2 + H2
example
Zn + 2HCL = ZnCl2 + H2
