The 21 amino acids can be arranged in many different ways. It is possible with just this small number of amino acids to create thousands of different types of proteins. Think of amino acids like they were little connecting blocks, such as legos. You have 21 of them before you. How many different ways can you arrange them? The formation of protein is similar.
The correct answer for this question is "<span>The mass of the products equals the mass of the reactants because the same matter is present."
All chemical reactions follow the Law of Conservation of Mass which states that mass cannot be created nor destroyed. This means that mass is constant before and after a process. If ever it seems like the mass is not the same, it is possible that the missing mass was converted to something else.</span>
The three changes of state during which energy is absorbed are:
1. Change from solid to liquid - Melting.
2. Change from liquid to gas - Vaporization
3. Change from solid to gas - Sublimation
All these changes of state require heat energy to break the attractive forces that hold the particles of the molecules together, so that they can move into more disorderly states. For instance, when heat is applied to a solid, the solid absorbs the heat and use it to break the attractive forces that are holding the molecules of the solid together. At a particular temperature, the attractive forces will be completely overcome and the solid framework will collapse, thus leading to the melting of the solid.
The answer is burning coal! Please forgive me if I get this answer wrong!
