Questions and Answers
Explain the concept of stoichiometry in chemistry and provide an example of its application in a chemical reaction?
Stoichiometry is the calculation of reactants and products in chemical reactions based on the balanced chemical equation. It involves determining the molar ratios of reactants and products. An example of its application is the reaction between hydrogen and oxygen to form water, where the stoichiometric ratio is 2:1.
Discuss the principles of chemical equilibrium and how it is achieved in a reversible reaction?
Chemical equilibrium occurs when the rates of the forward and reverse reactions are equal. It is achieved in a reversible reaction when the concentrations of reactants and products no longer change, but the reactions continue to occur. This occurs when the forward and backward reactions occur at the same rate.
Explain the concept of electronegativity and its significance in chemical bonding?
Electronegativity is the ability of an atom to attract shared electrons in a covalent bond. It is significant in chemical bonding as it determines the nature of the bond formed between two atoms, such as whether it is ionic, polar covalent, or nonpolar covalent, based on the difference in electronegativity between the atoms.
