A heavily wooded area needs additional solar collectors to meet energy demand. Which statement describes a possible environmental consequence of adding these collectors?

A.
The amount of air pollution will increase.

B.
The amount of water pollution will increase.

C.
More trees will need to be planted to insulate the solar collectors.

D.
Trees will need to be cleared for the solar collectors to work efficiently.

Answers

Answer:

I think not positive good luck tho

A heavily forested area is one that has a dense and large number of trees. The areas like mountainous tracks or the protected frosts areas of wildlife.

In order to have solar collectors that meet the demands of energy generation. Some parts of the forests may have to clear off. As for collecting the sunlight, there needs to be clear ground. As trees and forests absorb insolation.

Hence the option D is correct, trees need to to be cleared for working efficiently.

How to calculate the number of molecules in 18g of H2O

Answers

We, know molecular mass of water is, M = 16 g/mol .

Given mass of water, m = 18 g.

We know, number of moles is given by :

[tex]n = \dfrac{18\ g}{16 \ g/mol}\\\\n = 1.125\ moles[/tex]

Now, 1 mole of any compound contains 6.022 × 10²³ molecules.

So, number of moles in 1.125 moles of water is 1.125 × 6.022 × 10²³ =

6.77 × 10²³ molecules.

Hence, this is the required solution.

What will be the mass of 9.95 liters of propane gas (C3H8) at STP?

Answers

Answer:

19.5g

Explanation:

Given parameters:

Volume of propane gas = 9.95L

Unknown:

Mass of propane gas = ?

Solution:

To solve this problem, find the number of moles first.

At STP;

22.4L of gas makes up 1 mole

9.95L of gas will have a [tex]\frac{9.95}{22.4}[/tex] = 0.44mole

So;

Mass of propane gas = number of moles x molar mass

Molar mass of propane = 3(12) + 8(1) = 44g/mol

Mass = 0.44 x 44 = 19.5g

What is the molality of a solution made by dissolving 2 moles of NaOH in 6 kg
of water?
A. 0.33 mol/kg
B. 12 mol/kg
C. 3 mol/kg
D. 2 mol/kg

Answers

The molality of a solution : m = 0.33 mol/kg

Further explanation

Given

2 moles of NaOH in 6 kg of water

Required

The molality

Solution

Molality shows how many moles are dissolved in every 1000 grams of solvent.

m = n x (1000/p)

m = Molality

n = number of moles of solute

p = solvent mass (grams)

Input the value :

solute : NaOH

solvent : water

m = 2 moles : 6 kg

m = 0.33 mol/kg

why do astronauts on the moon seem like they're "Walking on springs" while on earth we are firmly attached to the ground

Answers

Because of the moon's considerably lower gravity. The moon's gravity is about 1/4 as strong as the earth's gravity.
Our muscles a built to carry us on the earth. The astronauts are used to walking on earth so when they push forward with their legs they tend to use the same amount of energy which is 4 times more than needed. That push causes them to rise, Newton's second law

The citizens of a town are aware of climate change, and they want to make changes to control it. One change they consider is replacing the nearby thermal power plant with a hydroelectric plant. If they want to make sure this change will help to slow climate change, which question should they ask?

Answers

Answer: How hydroelectric plant is better over thermal power plant in creating less pollution?

Explanation:

The thermal power plant utilizes the coal as a fuel. The heat energy so produce after burning coal is used for generating electrical energy. The burning of the coal results in the production of pollutants. The carbon dioxide is also a chief pollutant of coal burning. This can pollute the air.

The hydroelectric plant is better than thermal power plant in the sense no fuel is required for this purpose the energy from water currents are used for generating electrical energy.

So, the citizens should research about hydroelectric plant and try to know how it is efficient in providing routine energy supply and impact it exerts on the environment if used as a source of energy generation.
