Burning fossil fuels emits a number of air pollutants that are harmful to both the environment and public health. Sulfur dioxide (SO2) emissions, primarily the result of burning coal, contribute to acid rain and the formation of harmful particulate matter.

However, the use of solar panels is environment friendly. Solar power is renewable at absolutely no cost to supply energy infinitely.  Also, it is very low maintenance. Once installed, the solar power system can last twenty to thirty years.

Similarly wind (turbines) and water (hydroelectric power plants) are an endless source of energy without negatively affecting the environment.

I could tell Mr. Turner that burning fossil fuels emit a number of air pollutants that are harmful to both the environment and public health. Sulfur dioxide emissions, primarily the result of burning coal, participate in acid rain and the formation of harmful particulate matter. However, the use of solar panels is environment friendly. Solar power is renewable at absolutely no cost to supply energy infinitely.  Also, it is very low maintenance. Once installed, the solar power system can last twenty to thirty years.

What would happen if you left your dichloromethane/ethanol solvent mixtures uncovered?
Viktor [21]
Dichloromethane/ethanol solvent mixtures are substances composed of compounds that has a very high volatility. The higher the volatility of the substances, the faster it is for them to vaporized. 

If we leave the solution or the mixture uncovered then, it is easier for the vapors produced to escape the system to the atmosphere.
