Covalent compounds are composed of atoms that are linked via covalent bonds i.e. bonds formed by mutual sharing of electrons. This is in complete contrast to ionic compounds which are held together by ionic bonds, i.e. bonds formed by complete transfer of electrons from one atom to the other.

In the given examples we have:

Barium nitrate: Ba(NO3)2 - Ionic

Dinitrogen tetroxide: N2O4- Covalent

Boron trifluoride: BF3-Covalent

Ammonium sulfate: (NH4)2SO4- Ionic

Carbon tetrachloride: CCl4- Covalent

Barium chloride: BaCl2 - Ionic

A sample of gas occupies 300 mL at 100K. What is its volume when the
iris [78.8K]

If the temperature of the sample of gas increases to the given value, the volume also increases to 600mL.

<h3>What is Charles's law?</h3>

Charles's law states that "the volume occupied by a definite quantity of gas is directly proportional to its absolute temperature.

It is expressed as;

V₁/T₁ = V₂/T₂

Given the data in the question;

  • Initial temperature of gas T₁ = 100K
  • Initial volume of gas V₁ = 300mL
  • Final temperature T₂ = 200K
  • Final volume V₂ = ?

V₁/T₁ = V₂/T₂

V₂ = V₁T₂ / T₁

V₂ = ( 300mL × 200K ) / 100K

V₂ = 60000mLK / 100K

V₂ = 600mL

Therefore, if the temperature of the sample of gas increases to the given value, the volume also increases to 600mL.

The Center for Disease Control publishes articles explaining the causes of seasonal West Nile virus. Research proves mosquitoes
Goshia [24]

Answer:

The correct answer is - Mosquitoes transmit the virus as parasites which feed on the blood of host organisms and inject the virus during feeding.

Explanation:

According to the CDC, the seasonal West Nile virus is caused by the mosquitoes of freshwater transmit this disease to humans and others. These mosquitoes are feed on the birds and pick these viruses.

These viruses stick on mosquitoes and when they feed on the blood of humans they transmit these viruses by injecting viruses into the blood of humans.

Explain why some parts of our planet have very little seasonal change.
rosijanka [135]
Some parts of the planet undergo very little seasonal change due to their proximity to the equator and the poles. This means that their position relative to the sun and the earth's rotation varies hardly at all.

What is the net ionic equation for the reaction that occurs when you mix aqueous solutions of NaHCO3 NaHCO3 and HC2H3O2HC2H3O2
Verizon [17]

Explanation:

The net ionic equation of a reaction is obtained from the complete ionic equation after removing the spectator ions.

The balanced chemical equation for the reaction of sodium bicarbonate with acetic acid is shown below:

NaHCO_3(aq)+CH_3COOH(aq)->CH_3COONa(aq)+H_2O(l)+CO_2(g)

The complete ionic equation is:

Na^+(aq)+HCO_3^-(aq)+CH_3COO^-(aq)+H^+(aq)->CH_3COO^-(aq)+Na^+(aq)+H_2O(l)+CO_2(g)

The net ionic equation is:

HCO_3^-(aq)+H^+(aq)->H_2O(l)+CO_2(g)

Answer:The net ionic equation is shown below:

HCO_3^-(aq)+H^+(aq)->H_2O(l)+CO_2(g)
