Chemistry
1 answer:
deff fn [24]2 years ago
8 0

Answer:

When solutions of sodium carbonate and hydrochloric acid are mixed, the equation for the hypothetical double displacement reaction is: Na2CO3 + 2 HCl → 2 NaCl + H2CO3 Bubbles of a colorless gas are evolved when these solutions are mixed.

what are the differences between the double displacement reaction and the displacement reaction ? explain with a chemical equati
guajiro [1.7K]

In a displacement reaction, a more reactive element replaces a less reactive element from a compound. In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds.

Explaination:

Displacement chemical reaction :

A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. For instance, when iron is added to a copper sulphate solution, it displaces the copper metal.

Fe + CuSO4 → FeSO4 + Cu. When zinc is added to a copper sulphate solution, it displaces the copper metal. ...

Zn + CuSO4 → ZnSO4 + Cu.

etc.

Double Displacement Chemical Reaction :

Double displacement reactions take place mostly in aqueous solutions wherein the ions precipitate and exchange of ions takes place. For example, when a solution of barium chloride is mixed with sodium sulphate, a white precipitate of barium sulphate is formed rapidly. These reactions are ionic in nature.

Here are some examples of double displacement reaction: AgNO 3 + NaCl → AgCl + NaNO.

2NaCl + CaSO4 → Na2SO4+ CaCl.

H2SO4 + 2LiOH ⇌ Li2SO4 + 2H2O.

There are ________ unpaired electrons in the Lewis symbol for a nitride ion.
Anna71 [15]

Answer:

There are no unpaired electrons.

Explanation:

There are  no unpaired electrons in the Lewis symbol for a nitride ion({ N }^{ 3- }).The nitride ion has a charge of -3. The negative charge on the Nitride ion indicates a gain in electrons . Nitrogen has 5 valence electrons that is the number of electrons that are in its outer shell .The total number of electrons that the nitride ion has is equal to 5+3 = 8 electrons . Electrons usually appear in pairs and obey the octet rule therefore the nitride ion has four electron pairs no unpaired electrons.
