In this episode of Science Theater Dr. Carlson helps you understand the concept behind Density and how it relates to Mass and volume and how to calculate the Density of a substance if its Mass and Volume are known. The Density of various metals is demonstrated using aluminum, tin, zinc, lead and copper of the same mass but different sizes. The easiest way to measure the density of a substance is also mentioned. Next, Dr. Carlson measures his own density using a scale and a bathtub.

In this video, we learn how to balance an easy chemical equation. You can do your equation by testing it out with the actual chemicals. Watch and see what the reaction is as they start to mix together. To balance this reaction out, you will need to analyze the number of atoms that each element has on both sides of the equation. For it to be balanced, you must have the same number of products and reactants in the equation. You cannot create or destroy matter, you can only change its form, so r...
In this video, we learn how to easily balance chemical equations. There are two sides of a chemical equation, both must be equal to get the proper reaction. To balance these out, first write out the number of atoms that is on each element on each side of the equation. After this, you will need to find the multiple between the matching elements. Once you find this, you will be able to balance out the equation for each of the elements. When you do this, you will have the same mass and atoms on ...
This is a video tutorial in the Education category where you are going to learn how to balance a chemical equation step-by-step. The left side of the equation is called the reactants and the right side is the new products. What will be new products when silver nitrate reacts with ferric chloride? The left side will be written as Ag NO3 + Fe Cl. The valence of Ag is +1, NO3 is -1, Fe is +3 and Cl is -1. On the right side the silver cannot go with iron because both are positive. So, it will be ...

Then you write the symbols, write the charges, cross-over the charges from top to bottom, remove the charge and simplify the numbers and remove the 1s. for example, iron (II) phospahate. The "ate" ending implies that phosphate is polyatomic. The symbol ...
