Reactions Notes/WS
-Define Reaction:
-Define Reactant:
-Define Product:
Explain what the following symbols mean:
+
→
(s)
(l)
(g)
(aq)
The video will mention the term “diatomic”
What are diatomics?
There are 7 elements that exist naturally as a pair as long as it is not already in a compound. They are:
H2
N2
O2
F2
Cl2
Br2
I2
In a nutshell, if you see hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine or iodine in a
reaction by themself (meaning not part of a compound), it will exist with the subscript 2 after it.
Before moving on to the next page, look at the following equation. Label the reactants and label the
products.
CaCO3(aq)
+
2 HCl(aq)
🡪
CaCl2(s)
+
H2CO3(aq)
What does the + sign mean?
What does the arrow sign mean?
What does the symbol (aq) mean?
What does the symbol (s) mean?
