Biology: Chemistry in Biology: 08: Chemical Reactions - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: What are chemical reactions? A chemical reaction is a process in which substances interact to form different substances by breaking, forming, or rearranging their chemical bonds. Substances that take part in a chemical reaction may be ionic or covalent compounds, as well as the atoms, ions, or molecules of some elements. Let's look at an example of a chemical reaction. Photosynthesis is a chemical reaction in which plants make food by using the sun's energy to combine carbon dioxide from the air and water from the soil into a sugar called glucose and oxygen. In this reaction, carbon dioxide and water are called reactants, because they're the substances changing by combining or reacting together. Glucose and oxygen are called products because they're the new substances produced by the reaction. Scientists write a chemical reaction in the form of a chemical equation. A chemical equation includes the reactants' chemical formulas on the left and the products' chemical formulas on the right. Notice that the reactants and the products are built from the same elements, carbon, oxygen, and hydrogen. Products must contain the same amount and type of elements that were in the reactants, and products never contain different elements than the reactants. In this reaction, the chemical formulas for the reactants are CO2 for carbon dioxide, and H2O for water. The chemical formulas for the products are C6H12O6 for glucose, and O2 for oxygen. We are not done yet because the equation is not balanced. This is necessary due to the law of conservation of matter, it states that matter can't be created or destroyed, but can only change forms. So to balance the equation, we have to make sure that the number of atoms of each element in the reactants is equal to those in the products, this is because a chemical reaction must abide by the law of conservation of matter, no atoms are created or destroyed. Here's the balanced version of this equation. It shows six molecules of carbon dioxide reacting with six molecules of water to produce one molecule of glucose and six molecules of oxygen. The numbers in front of the formulas are called coefficients. They indicate the number of molecules of each reactant and product. If there's no coefficient, it's understood to mean one molecule of that substance. To review, in a chemical reaction chemical bonds in reacting substances are broken then reformed to make different substances. The reacting substances are called reactants. The substances produced are called products. A chemical equation is a written expression of a chemical reaction, it includes the chemical formulas of both the reactants and the products. In a balanced chemical equation, the number of atoms of each element in the reactants equals those in the products. [music]

What attorneys say about MLA and The Doe Report:
"Medical Legal Art wins our firm's highest accolades for professionalism and exhibit quality. In fact, many of the doctors I work with request color copies of your outstanding artwork to show to patients during the informed consent process."

Jeanne Dolan, BSRN, AlNC
Legal Nurse Consultant
Golden Valley, MN

"At 3 PM it hit me--I needed exhibits of a tracheostomy, a coronary artery bypass and a deep vein thrombosis--all in time for a for-trial video deposition the next day. The Doe Report had each exhibit on line. In addition, I ran across an exhibit I hadn't even thought of: reduced ejection fraction after a heart attack. Because this was a video deposition, I could use the e-mail version of the medical exhibit, print it on my color copier, and let the camera zoom in. For $400, less than one blow-up by one of The Doe Report's competitors, I got four first-rate exhibits in less than a day. The Doe Report saved me time and money."

"A few words about The Doe Report: recently in a brachial plexus injury case, we used an image from The Doe Report to demonstrate the injury. We downloaded the PDF file image, and were amazed at the quality. The hard copies that you sent were even more clear. As well, we could not have been happier when you customized the image and reversed the injury from the left shoulder to the right shoulder, which is where our client's injury was.

The speed and cost-effectiveness of the product made it the perfect tool for our purposes. We will use The Doe Report again in future cases."

"I just wanted to let you know that after several days on trial, I settled [my client's] construction accident case for $4.5 million. Immediately after the jury was discharged, I spoke with several jurors who told me that they really appreciated the medical illustrations for their clarity in dealing with [my client's] devastating injuries. They also expressed their gratitude in being able to read from a distance all of the notations without difficulty. Obviously, the boards were visually persuasive. I am certain that this contributed to our successful result."
