What does resonance result in?

Tcecarenko [31]

louder sounds

Explanation:

Resonance results in louder sounds.

Resonance is a phenomenon that produces a large vibration as a result of smaller vibration that causes the resonating body to vibrate at its own natural frequency.

Resonance results in sound amplification and causes louder sounds. Increasing vibration results in the production of a louder sound.

Describe the reaction below by listing the

rjkz [21]

Answer:

The covalent bond in Cl₂ is break and combine with sodium to form NaCl through ionic bond.

Explanation:

Chemical equation:

Na + Cl₂ → NaCl

Balanced chemical equation:

2Na + Cl₂ → 2NaCl

The given reaction indicate the formation of sodium chloride.

Sodium chloride is an ionic compound. It is formed by the reaction of chlorine and sodium. The type of bond in Cl₂ is covalent. Both chlorine atoms are tightly held together through sharing of electrons. When sodium chloride is formed the covalent between the chlorine atoms are break and it react with sodium . The chlorine toms thus gain the one electron from the sodium atom and became negative ion while sodium by losing its one valance electrons became positive ions. The strong electrostatic forces are develop between them and ionic bond is formed.

Below is the Lewis structure of the hydrogen cyanide molecule.

lianna [129]

Answer :

The number of bonding pairs of electrons around the hydrogen atom = 2

The number of lone pairs of electrons around the hydrogen atom = 0

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, $HCN$

As we know that carbon has '4' valence electrons, hydrogen has '1' valence electrons and nitrogen has '5' valence electrons.

Therefore, the total number of valence electrons in $HCN$ = 1 + 4 + 5 = 10

According to Lewis-dot structure we conclude that, there are 8 number of bonding electrons and 2 number of non-bonding electrons.

The number of bonding pairs of electrons around the hydrogen atom = 2

The number of lone pairs of electrons around the hydrogen atom = 0

The molar heat capacity of an unknown substance is 92.1 J/mol-K. If the unknown has a molar mass of 118 g/mol, what is the speci

dlinn [17]

Answer : The specific heat (J/g-K) of this substance is, 0.780 J/g.K

Explanation :

Molar heat capacity : It is defined as the amount of heat absorbed by one mole of a substance to raise its temperature by one degree Celsius.

1 mole of substance releases heat = 92.1 J/K

As we are given, molar mass of unknown substance is, 118 g/mol that means, the mass of 1 mole of substance is, 118 g.

As, 118 g of substance releases heat = 92.1 J/K

So, 1 g of substance releases heat = $\frac{92.1}{118}=0.780J/g.K$

Thus, the specific heat (J/g-K) of this substance is, 0.780 J/g.K
