the numbers in a chemical equation
{"Image DocumentName": "The Numbers in a Chemical Equation", "Image ImageDescription": "When we write a chemical equations, there are two different numbers that are extremely important, subscripts and coefficients. Subscripts are the small numbers located on the right of each atom in a compound that tell you how many of each type of atom are in the compound. Ex: H2SO4 has 2 Hydrogen atoms, 1 Sulfur atom (we never write a subscript of 1!), and 4 oxygen atoms. If there is a polyatomic ion in parenthesis, we need to multiply the subscript outside the parenthesis by the subscript on each atom in the polyatomic ion. Ex: Mg(NO3)2 has 1 magnesium atom, 2 (or 2 x 1) nitrogen atoms, and 6 (or 2 x 3) oxygen atoms.", "Image XResolution": "200", "Image YResolution": "200", "Image ResolutionUnit": "Pixels/Inch", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
