The document covers the process of balancing chemical equations, emphasizing the importance of maintaining the same amount of reactants and products as dictated by the law of conservation of mass. It provides strategies for balancing equations, such as creating an inventory of chemicals and methodically adjusting coefficients without changing subscripts. Additionally, it discusses the relationship between matter and energy in chemical reactions, particularly in relation to processes like photosynthesis.

1. • Balancing a chemical equation refers to
establishing the mathematical relationship
between the quantity of reactants and
products.

233. • An easy one…
• ___ Na + ___Cl  ____ NaCl
• The original equation is Na + Cl = NaCl.
• The thing is, chlorine is one of 7 elements that doesn't like
to be alone, so it's always 'Cl2', making the equation Na +
Cl2 = NaCl.
• However, this is no longer balanced. So what you do is add
a '2' onto NaCl, making it Na + Cl2 = 2NaCl.
• Now the chlorine is balanced, but the sodium isn't.
• After that, to balance the sodium, you add a '2' in front of
'Na' making the equation 2Na + Cl2 = 2NaCl.
