The main difference is in the presence of a carbon atom; organic compoundswill contain a carbon atom (and often a hydrogen atom, to form hydrocarbons), while almost allinorganic compounds do not contain either of those two atoms. While mostinorganic compounds do not contain carbon, there are a few that do.
An organic compound is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon
Inorganic compounds can be defined as any compound that is not organic compound. Some simple compounds which contain carbon are usually considered inorganic. These include carbon monoxide, carbon dioxide, carbonates, cyanides, cyanates, carbides, and thiocyanates.
Answer:
Double replacement
Precipitation reaction
Explanation:
You have the reaction:
REACTANTS PRODUCTS
BaCl₂ (aq) + Na₂SO₄ (aq) ⇒ 2NaCl (aq) + BaSO₄(s)
The general form of a double replacement reaction is the following:
AB + CD ⇒ CD + AB
The reactants basically, exchanged partners. In the case of your problem, Barium(Ba) and Sodium(Na) switched places. So this makes it a double-replacement reaction.
Now how do I know it is a precipitation reaction. A precipitation reaction occurs when two solutions combine and salt is formed. Salt is solid, so how do I know that's what occured? Look at your equation again:
BaCl₂ (aq) + Na₂SO₄ (aq) ⇒ 2NaCl (aq) + BaSO₄(s)
aq means aqueous (liquid)
s means solid
If you look at the product formed in the reaction, from two solutions, it formed a solid. So this is your clue as to why it is a precipitation reaction.
Explanation: In solids, particles are very closely packed in an orderly arrangement in a lattice and only vibrate in fixed positions. The forces of attraction between them are very strong. This allows them to overcome the forces of attraction that hold the other phases closer together
Each sample has the same number of molecules;
According to the Avogadro's number, or constant, one mole of a substance contains 6.022 × 10^23 constituents particles, usually atoms or molecules.
Therefore, 1 mole of oxygen contains 6.022 × 10^23 molecules,similar to 1 mole of nitrogen, which also contains 6.022 ×10^23 molecules
Through the process of conduction, heat van be trnafered between two solids.
