mario62 [17]3 years ago
4 0

The advantages of the hydropower are:

- It is renewable

- It is a clean source of energy

- Matches current demand

- It is stable and reliable

- Requires low operating cost

The disadvantages of the hydropower are:

- Causes environmental damage

- Cost of building is expensive

- May cause droughts

- May cause floods in lower areas

- Shortage of water supply

The hydroelectric power has its prons and cons. It is very expansive for building, and it causes environmental damage in the river systems, but it also causes hazards like droughts and floods at certain areas. On the other side, once established it is very cheap, and it gets the job done when it comes to electricity. It is also an energy that is not polluting, and it is sustainable, reliable, and renewable.

The electronegativity values of carbon, hydrogen, and nitrogen are compared in the table.
Fofino [41]

Answer:

C. CH₄ is less than NH₃ because the NH bond is more polar than the CH bond

Explanation:

The intermolecular forces between ammonia is far stronger than for methane. Between the molecules of ammonia we have the presence of hydrogen bonds. This bond is absent in methane.

Hydrogen bonds are one of the strongest intermolecular forces. It is as a result of the electrostatic attraction between the hydrogen atom of one molecule and the electronegative atom N, O and F of another molecule.

  • This strong interaction is absent in methane which has just dipole - dipole attraction.

The strength of the hydrogen bond depends on the electronegativity of the combining atoms.

Which substance is a base? HCOOH RbOH H2CO3 NaNO3
Alex Ar [27]

Answer:

RbOH

Explanation:

For this question, we have to remember what is the definition of a base. A base is a compound that has the <u>ability to produce hydroxyl ions</u> OH^-, so:

AOH~->~A^+~+~OH^-

With this in mind we can write the <u>reaction for each substance:</u>

HCOOH~->~HCOO^-~+~H^+

RbOH~->~Rb^+~+~OH^-

H_2CO_3~->~CO_3^-^2~+~2H^+

NaNO_3~->~Na^+~+~NO_3^-

The only compound that fits with the definition is RbOH, so this is our <u>base</u>.

I hope it helps!
