The question asks to explain the meaning of a balanced chemical equation both at molecular and macroscopic levels. Concept Introduction: Daltons’ atomic theory states that matter cannot be created or destroyed. Since matter is composed of atoms and molecules in order to be consistent with this principle one has to make sure that the number of atoms/molecules of each type of atoms are equal on both sides of the reaction. There can be many ways of achieving this using several set of coefficients in front of each reactants and products. But the combination with the lowest possible integers are the valid stoichiometric coefficients in a balanced chemical reaction .

Solution Summary: The author explains the meaning of a balanced chemical equation at molecular and macroscopic levels.
Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.

Interpretation Introduction
Interpretation:
The question asks to explain the meaning of a balanced chemical equation both at molecular and macroscopic levels.
Concept Introduction:
Daltons’ atomic theory states that matter cannot be created or destroyed. Since matter is composed of atoms and molecules in order to be consistent with this principle one has to make sure that the number of atoms/molecules of each type of atoms are equal on both sides of the reaction.
There can be many ways of achieving this using several set of coefficients in front of each reactants and products. But the combination with the lowest possible integers are the valid stoichiometric coefficients in a balanced chemical reaction.
For each reaction shown below follow the curved arrows to complete each equationby showing the structure of the products. Identify the acid, the base, the conjugated acid andconjugated base. Consutl the pKa table and choose the direciton theequilibrium goes. However show the curved arrows. Please explain if possible.
A molecule shows peaks at 1379, 1327, 1249, 739 cm-1. Draw a diagram of the energy levels for such a molecule. Draw arrows for the possible transitions that could occur for the molecule.
In the diagram imagine exciting an electron, what are its various options for getting back to the ground state?
What process would promote radiation less decay?
What do you expect for the lifetime of an electron in the T1 state?
Why is phosphorescence emission weak in most substances?
What could you do to a sample to enhance the likelihood that phosphorescence would occur over radiationless decay?
Rank the indicated C—C bonds in increasing order of bond length. Explain as why to the difference.
