<h2>Answer:</h2>
The correct answer is option C which is chemical waste.
<h3>Explanation:</h3>
- Wind is the renewable source of the energy. The air has energy in it which is used to run the generator to produce electrical energy from the mechanical energy of wind.
- Wind energy is perfect in sense of pollution. It does not create any chemical waste because there is no conversion or production of chemical energy involve in this energy production.
- While bats and birds death is caused by the fans used to run generators and a huge noise is also created by the wind energy production.
Answer: i dont understand
Explanation:
Answer: Changing the amount of solute and volume of solvent we can change physical properties of the given salt water solution.
Explanation:
Physical properties are defined as the properties which does not cause any change in chemical composition of a substance. For example, density, mass, volume, etc are all physical properties.
When we take a salt water solution then on adding more amount of salt into the water there will occur change in density of the solution as density is mass present per liter of solution.
Also, if we add more amount of solvent then there will occur change in volume of the solution.
Hence, in both the cases physical properties of the solution are changing and no change in its chemical composition is taking place.
Answer:
About 7.89g/cm^3, I think.
Explanation:
Find the volume. Divide the mass by the volume.
