========================
Let’s find out below and learn how to balance a chemical equation. As you have already learned earlier, mass can neither be created nor destroyed. This law applies to a chemical reaction . Here are some basic steps that help when you balance chemical equations. 1. Leave any type of atoms that are present in their elemental state alone until the end. This is particularly true if . Tips for Balancing that (sometimes) Help! • Stuck? Erase and start over! • Try to balance atoms that appear in the fewest number of places first • Try to leave any diatomics until the end • . Balancing Equations Notes: Chemical equations must be balanced on both sides according to the Law of Conservation of Mass, which says that matter cannot be created or destroyed. Therefore, atoms that are present on one side of the equation must be present on the other side as well. Example: H 2 + O 2 H 2 O Reactant Product. Balancing Chemical Equations Objectives: • to read chemical equations • to identify elements by their chemical symbol • to count atoms • to identify the coefficients and subscripts in a chemical equation. • to label the reactants and products of a chemical equation • to balance chemical equations. Balancing chemical reactions then allows one to determine stoichiometry calculations by understanding the ratio between reactants and/or products. This worksheet includes some rules and guidelines to help you balance chemical equations. 1.) The formulas of the reactants and products cannot be changed, do not alter subscripts or charges. 2.).

Cardiac Cowboys
The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
