Br2 or O2 or N2 or H2 or F2 or I2 etc.
Atoms of elements that are nonmetals tend to gain electrons and atoms of metallic elements tend to lose electrons. Metals have few electrons in their valence shells.
By losing those electrons, these metals achieve noble gas configuration and satisfy the octet rule.
Nonmetals that have close to 8 electrons in their valence shells readily accept electrons to achieve noble gas configuration.
An example is the reaction between calcium and oxygen. Calcium is a metal and has 2 valence electrons. Oxygen is a nonmetal and has 6 valence electrons.
Calcium gives up its two valence electrons and oxygen accepts them and an ionic bond is established resulting in the formation of anew compound namely calcium oxide.
Answer:
Double replacement
Explanation:
The given reaction is double replacement reaction.
CaCO₃ + 2HCl → CaCl₂ + H₂CO₃
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
while,
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
Decomposition:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
