If you do not want to read about survival rates for small cell lung cancer, stop reading here and skip to the next section. The 5-year survival rate refers to the percentage of patients who live at least 5 years after their cancer is diagnosed.Of course, many of these people live longer than 5 years.To get 5-year survival rates, doctors look at people who were treated at least 5 years ago. Improvements in treatment since then may result in a more favorable outlook for people now being diagnosed with small cell lung cancer (SCLC).f course, many of these people live longer than 5 years.

Answer: A chemical equation is a written representation of the process that occurs in a chemical reaction. A chemical equation is written with the reactants on the left side of an arrow and the products of the chemical reaction on the right side of the equation.
In a balanced chemical equation, both the numbers of each type of atom and the total charge are the same on both sides. Equation 3.9 and Equation 3.10 are balanced chemical equations. What is different on each side of the equation is how the atoms are arranged to make molecules or ions. A chemical reaction represents a change in the distribution of atoms but not in the number of atoms.
