What is a representative element in basic chemistry terms? Groupings of the Periodic Table: The periodic table consists of six different groupings of elements. Group 1 consists of the alkali metals, group 2 consists of the alkaline earth metals, groups 3-12 consist of the transition metals, ...
What chemical components of nucleotides represent the 3' and 5' ends of a DNA strand? What is the nucleotide base found in RNA but not in DNA? What is the definition of a nucleotide? What are the components of DNA and RNA molecules?
What is entropy? How was it introduced in science? What is its significance in chemistry? Does the melting of ice result in a positive change in the entropy of the system? Explain. What is the change in entropy (in J/deg) when a 245...
In physics, the letter μ is commonly used to represent the coefficient of friction and magnetic permeability. The coefficient of friction refers to the ratio of the frictional force (F) resisting the motion of two surfaces that are in contact to the normal force (N) that's pressing the two...

But why isn't there in general a which would represent the total potential energy of the system due to force interactions?One last question: Both fission and fusion have less mass in their final states. Can I engineer a process where I go fission>Fussion>fission>fusion>fission... and ...
What does a neutral pH of 7 actually represent? What does pH stand for in chemistry? What is the strongest acid on the pH scale? What are the pH ranges for acids and bases? What is the pH level of sodium bicarbonate? What is the pH of distilled water?
Chemistry focuses on the properties and reactivity of the chemical elements. An element is defined as a pure substance, in which the smallest representation is an atom, with every atom of a particular element containing the same number of protons in its nucleus. For example, the element of hel...
