How is electronegativity related to covalent bonding?
Zolol [24]

Answer:

Atoms must have similar electronegativities in order to share electrons in a covalent bond.

Explanation:

Covalent bonding is one of the bondings that occurs between the atoms of elements. It is the bonding in which atoms share their valence electrons with one another. However, the ELECTRONEGATIVITY, which is the ability of an atom to be attracted to electrons play a major role in the formation of covalent bonds.

When atoms of different electronegativities combine, the more electronegative atom pulls more electrons towards itself, hence, an IONIC bond is formed. However, when the electronegativities of the atoms are similar, the sharing of their electrons becomes stronger. Hence, ATOMS MUST HAVE SIMILAR ELECTRONEGATIVITIES in order to share electrons in a covalent bond.

How many molecules are in 1.2 moles of H20?​
Otrada [13]
<h3>Answer:</h3>

7.226 × 10^23 molecules.

<h3>Explanation:</h3>
  • A compound is a substance that is made by two or more atoms from different elements.
  • A mole of a compound contains a number of molecules equivalent to Avogadro's number,  6.022 × 10^23.
  • That is, one mole of a compound contains 6.022 × 10^23 molecules.

In this case we are given;

Number of moles of H₂O as 1.2 moles

But, 1 mole of H₂O contains 6.022 × 10^23 molecules.

We are required to calculate the number of molecules present;

  • To calculate the number of molecules we are going to multiply the number of molecules in one mole by the number of moles.
  • Therefore;

Number of molecules = 1.2 moles × 6.022 × 10^23 molecules/mole

                                    = 7.226 × 10^23 molecules.

Thus, 1.2 moles of water contains 7.226 × 10^23 molecules.

Barbiturates are synthetic drugs used as sedatives and hypnotics. Barbital ( = 184.2 g/mol) is one of the simplest of these drug
DanielleElmas [232]

Answer:

118.75°C is the boiling point of a solution.

Explanation:

Mass of the solute that is barbiturates = 42.5 g

Molar mass of a solute = 184.2 g/mol

Moles of solute = \frac{42.5 g}{184.2 g/mol}=0.2307 mol

Mass of the solvent that acetic acid = 825 g = 0.825 kg

molality=\frac{\text{Moles of solute}}{\text{Mass of solvent}}

Molality of the solution (m):

m=\frac{0.2307 mol}{0.825 kg}=0.2796 m

Elevation in boiling point is given as:

\Delta T_b=i\times K_b\times m

i = 1 (organic compound)

=1\times 3.07^oC/m\times 0.2796 m=0.8585^oC

\Delta T_b=T_b-T

T_b = Boiling temperature of solution.

T = boiling temperature of solvent that is acetic acid=117.9°C

0.8585^oC=T_b-117.9^oC

T_b=118.75 ^oC

118.75°C is the boiling point of a solution.
