Imagine a beach populated with sunbathers and swimmers. As those basking in the sun get too hot and want to cool off, they head into the surf to swim. As the swimmers tire, they head to the beach to rest. If these two rates of transfer (sunbathers entering the water, swimmers leaving the water) are equal, the number of sunbathers and swimmers would be constant, or at equilibrium, although the identities of the people are constantly changing from sunbather to swimmer and back. An analogous situation occurs in chemical reactions. Reactions can occur in both directions simultaneously (reactants to products and products to reactants) and eventually reach a state of balance.

These balanced two-way reactions occur all around and even in us. For example, they occur in our blood, where the reaction between carbon dioxide and water forms carbonic acid $\left({\text{HCO}}_{3}{}^{\text{−}}\right)$ ( [link] ). Human physiology is adapted to the amount of ionized products produced by this reaction $\left({\text{HCO}}_{3}{}^{\text{−}}$ and H + ). In this chapter, you will learn how to predict the position of the balance and the yield of a product of a reaction under specific conditions, how to change a reaction's conditions to increase or reduce yield, and how to evaluate an equilibrium system's reaction to disturbances.

what is dative bond?
A coordinate covalent bond, also known as a dative bond or coordinate bond is a kind of 2-center, 2-electron covalent bond in which the two electrons derive from the same atom.

what if we try copper and the hydrogen what happened
law of definite proportion
Law of Definite Proportion states that all pure samples of the same chemical compound contains the same elements in proportion by mass

what is chemistry
It is that branch of Science which deals with the study of composition, structure and properties of matter .... Ok

why does liquids have no fixed shape but a fixed volume?
it has no fixed shape
SHOLA
liquids are shaped acc to the container they are placed in since their particles are mobile ie they move throughout the whole liquid.hence they have no fixed shape .

what are the easiest way to understand chemistry intensively?
i dont think there is any easy way than reading from the begining to the end
