A is the answer and since I’m here you may as well give brainliest bc it gives you points
Answer:
mechanical energy to electrical energy
Explanation:
The water turns the turbine with produces mechanical energy so the generator converts it to electrical energy
Single bond: 1 pair of electrons
Double bond: 2 pairs of electrons
Triple bond: 3 pairs of electrons
A large activation energy is required to break the double bonds of unsaturated hydrocarbons.
<h3>What are Unsaturated hydrocarbons ?</h3>
Unsaturated hydrocarbons are defined as the hydrocarbons in which double or triple bonds are present between two adjacent carbon atoms. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is CnH2n and CnH2n-2
- In unsaturated hydrocarbons, more number of bonds are formed, thus the bond strength of the bonds formed will be more because the orbitals come closer to each other.
- As, bond strength of unsaturated hydrocarbons are more. So, more energy will be required to break the bond between them.

<u>Answer:</u> The amount of energy required to raise the given amount of temperature is 6400 J
<u>Explanation:</u>
To calculate the heat absorbed by the lead, we use the equation:

where,
q = heat absorbed
m = mass of lead = 200 g
c = heat capacity of lead = 0.128 J/g°C
= change in temperature = 250°C
Putting values in above equation, we get:

Hence, the amount of energy required to raise the given amount of temperature is 6400 J
