Your neighbor Mr. Turner doesn't think that alternative energy resources like water, wind, or solar are important. "Why not just

do what we have always done," he asks. Justify the use of alternative energy resources instead of fossil fuels with at least one real life example to help him understand.

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.

Answer:

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.

How many molecules are there in 237 grams of CCl4
Otrada [13]
Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We calculate as follows:

237g CCl4 (1 mol / 153.81 g ) (6.022 x 10^23 molecules / 1 mol ) = 9.28x10^23 molecules

The ksp of lead iodide is 7.1 × 10-9. a chemical engineer adds 0.0025 mol of ki to a solution of 0.00004 mol pb(no3)2 in 500 ml
inn [45]
Answer is: n<span>o, because the ion product is less than the Ksp of lead iodide. </span>

Chemical dissociation 1: KI(s) → K⁺(aq) + I⁻(aq).
Chemical dissociation 2: Pb(NO₃)₂(s) → Pb²⁺(aq) + 2NO₃⁻(aq).
Chemical reaction: Pb²⁺(aq) + 2I⁻(aq) → PbI₂(s).
Ksp(PbI₂) = 7.1·10⁻⁹.
V = 500 mL ÷ 1000 mL/L = 0.5 L.
c(KI) = c(I⁻) = 0.0025 mol ÷ 0.5 L.
c(I⁻) = 0.005 M.
c(Pb(NO₃)₂) = c(Pb²⁺) = 0.00004 mol ÷ 0.5 L.
c(Pb²⁺) = 0.00008 M.
Q = c(Pb²⁺) · c(I⁻)².
Q = 8·10⁻⁵ M · (5·10⁻³ M)².
Q = 2·10⁻⁹; <span> the ion product.</span>
