What is double bond,triple bond,lone pair and single bond
AlladinOne [14]

In covalent bonds, atoms share electrons. These shared electrons are known as, well, covalent bonds!

In a covalent bond, each atom contributes one electron, meaning that for every bond, there are 2 electrons residing in it.

Definitions:

A single bond is a covalent bond that contains 2 electrons.

A double bond is a covalent bond that contains 4 electrons

A triple bond is a covalent bond that contains 6 electrons

It's very common for atoms to not use all of their electrons while bonding, which means that some will be left out and aren't used in any bonds. These are called lone pairs.

Definition:

A lone pair is a pair of electrons that aren't used in bonding, and therefore remain with its original atom.

The molar mass of carbon dioxide (CO2) is 44.01 g/mol. The molar mass of water (H2O) is 18.01 g/mol. A reaction uses 528 g of CO
Black_prince [1.1K]
CO₂  +  H₂O  ------->  H₂CO₃

moles of CO₂ = \frac{MASS  of  Carbon}{ MOLAR  MASS}
              
                       = \frac{528  g}{44.01  g / mol}
 
                       =  11.997 mol

mole ratio of  CO₂  :  H₂O  =   1  :  1
           
            ∴ moles of H₂O  =  (`11.997 mol )  *  1
                                       =  11.997 mol
                                       ≈  12  mol

If objects with a greater mass have greater gravitational pull, why is our solar
STatiana [176]

Answer:

It's too far away

Explanation:

According to classical mechanics, gravitational pull is inversely proportional to the distance squared; as the distance increases, the gravitational pull decreases at a faster and faster rate. Since Alpha Centauri A is a few lightyears (Tens of trillions of kilometers away), without even needing to calculate the force of gravity, it is very miniscule.

Why would you need to heat the hydrate up to 250 degrees if water boils at 100 degrees Celsius? Do you think that the boiling po
sergeinik [125]

Explanation:

The pure form of water has a boiling point of 100°C. Boiling point is a physical property of matter and it shows that at such temperature, a liquid substance will change state to vapor.

Pure water is made up of 2 atoms of hydrogen and 1 atom of oxygen. The only intermolecular forces between them is the hydrogen bonds that must be broken for the water to boiling off.

In hydrate, water is present in another form. The water is attached to another compound.

For a pure liquid, the they have reasonably constant boiling point and low boiling range.

Impurities such as the other part of the hydrate causes the elevation of the boiling point and the widening of the boiling range for impure substances.

We are no longer dealing with just hydrogen bonds, other molecular interactions are now involved and they need to be accounted for.
