CHEMISTRY
Natural to Synthetic
&
Conservation of Mass
MS – PS1 - 3
Gather and make sense of information
to describe that synthetic materials
come from natural resources and
impact society.
MS – PS1 - 5
Develop and use a model to describe
how the total number of atoms does
not change in a chemical reaction and
thus mass is conserved.

Synthetic Material from Natural Resources
• Synthetic material - made through the
use of chemicals, especially to imitate a
natural product.
• Natural resource - existing in or caused
by nature; not made or caused by
humankind.
• Impact – to have a strong effect on
someone or something.
Brainstorm….
• What SYNTHETIC PRODUCTS do you know of?

Chemical Reactions Review…
1. Is the process where physical and
chemical properties of the original
substance change into a new substance
with different physical and chemical
properties
– If there is no new substance there has
been no reaction
• Reactants enter into the reaction
• Products are produced by the reaction
Chemical Reactions Review…
2. Chemical equations describe
chemical reactions using symbols
and numbers.
2Na + SrCl2  Sr + 2NaCl
a) Coefficients (in red)
–
–
The large numbers in front of chemical
formulas.
The number of molecules of the
substance in the reaction
Chemical Reactions Review…
2. Chemical equations describe
chemical reactions using symbols
and numbers.
2Na + SrCl2  Sr + 2NaCl
b) Subscripts (in Green)
–
–
The small numbers to the lower right of
chemical symbols
Represent the number of atoms of each
element is in the molecule
Chemical Reactions Review…
3. Atoms can neither be created nor
destroyed during a chemical
reaction…Mass MUST remain constant


You have to end up with the same number of
atoms you started with, but in a different
arrangement
So balanced equations have the same number
of atoms on each side of the YIELDS ““ sign
Law of Conservation of Mass
Balancing Chemical Equations
(ALWAYS USE PENCIL)
1. Check for DIATOMIC molecules
H2 , N2 , O2 , F2 , Cl2 , Br2 , I2 , and At2
–
You cannot change the subscripts of
these elements in an equation…
whenever they are by themselves,
these must be written with the
subscript 2.
Balancing Chemical Equations
2. Count the number of atoms on each side of
the reaction:
___Na + ___MgCl2  ___Mg + ___NaCl

Sodium=____  Sodium=____
1  Magnesium =____
1
Magnesium=____
2  Chlorine=____

2. Balance the metals first
then the nonmetals

Balancing Chemical Equations
3. If they are in your equation, balance
OXYGEN
then HYDROGEN last
4. Recount all atoms and check your work!
–
Work from the bottom to top until you find
any error.
5. If every coefficient will reduce, rewrite in
the simplest whole number ratio

1. ___Mg + ___O2  ___MgO
2. ___Ca + ___O2  ___CaO
3. ___H2O2  ___H2O + ___O2
4. ___N2 + ___H2  ___NH3
5. ___Cu2O + ___C  ___Cu+ ___CO2
