Explanation:
H2O : 2 covalent bonds are established between O atom and 2 H atom (H--O--H) by mutual shearing of their valence electrons.
The formula unit for Li and O is —————-> Li2O
Answer:
The rate would be lower and the concentration of reactants would be lower.
Explanation:
The rate of a chemical reaction depends on the rate constant and the concentration of reactants.
For Ex:
For a reaction experimentally given by A + B ----> C + D
Rate = k[A][B]
where k is the rate constant
[A] = concentration of reactant A
[B] = concentration of reactant B
As the reaction proceeds,the concentration of reactant decrease and concentration of products increase.Rate constant k depends only on temperature and activation energy.Hence it will remain constant throughout the reaction assuming that reaction is carried out at constant temperature and pressure.
Hence rate will depend only on concentration of reactants and hence decrease with decrease in concentration of reactants.
Answer:An iodide ion is the ion I−. Compounds with iodine in formal oxidation state −1 are called iodides. This page is for the iodide ion and its salts, not organo iodine compounds. In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate.
