Your Answer: Answer Question Calculate the molarity of a solution prepared by dissolving 19.89 grams of LiF (OR Li F) to total solution volume of 0.902 liters. Do not type units with your answer. Your Answer:
Electronic Effects
The effect of electrons that are located in the chemical bonds within the atoms of the molecule is termed an electronic effect. The electronic effect is also explained as the effect through which the reactivity of the compound in one portion is controlled by the electron repulsion or attraction producing in another portion of the molecule.
Drawing Resonance Forms
In organic chemistry, resonance may be a mental exercise that illustrates the delocalization of electrons inside molecules within the valence bond theory of octet bonding. It entails creating several Lewis structures that, when combined, reflect the molecule's entire electronic structure. One Lewis diagram cannot explain the bonding (lone pair, double bond, octet) elaborately. A hybrid describes a combination of possible resonance structures that represents the entire delocalization of electrons within the molecule.
Using Molecular Structure To Predict Equilibrium
Equilibrium does not always imply an equal presence of reactants and products. This signifies that the reaction reaches a point when reactant and product quantities remain constant as the rate of forward and backward reaction is the same. Molecular structures of various compounds can help in predicting equilibrium.
Solve this
Since you have posted multiple questions, we will solve only first question for you. If you want any specific question to be solved, please re post only that question.
Number of moles of a substance is equal to the mass of substance divided by its molar mass. Write the expression of number of moles.
where m is the mass and MM is the molar mass of the substance.
Calculate the number of moles of NaCl.
So, the number of moles of NaCl are 0.373 mol.
