Which of the following is not an option for solving the world water crisis? a. desalination b. finding new sources of freshwater c. reducing overconsumption d. wastewater treatment plants Please select the best answer from the choices provided A B C D
Answers
Answer:
Option(b)
Finding new sources of fresh water is not the correct method For solving the world water crisis the solution
Explanation:
Very small amount of water available on earth is freshwater and can be used by humans for drinking and other basicnecessities. Finding a new source for fresh water is a difficult also there is an no source found yet according to physical geography of the earth
Water consumption is need of the hour as the population of 7 billion can not survive without it and reducing over consumption can help savehugeamounts of water.
Answer:
The correct answer is option b. finding new sources of water
Explanation:
The other options are more proactive ways of alleviating the crisis, while finding new sources of freshwater is hardly an option. That would likely involve melting the glaciers to extract the Earth's largest fresh water reserves, which would subsequently destroy polar ecosystems and alter the thermohaline circulation of water across the globe, which relies heavily on the Earth's polar regions and has a large effect on the planet's climate.

b. 0.306g
c. 3.26g
d. 765mL
Answers
Answer:
Option A. 765g
Explanation:
From the question given, we obtained the following:
Density = 15.3 g/mL
Volume = 50mL
Mass =?
Density = Mass /volume
Mass = Density x volume
Mass = 15.3 x 50
Mass = 765g

The number of moles in the 4.30 g of SiH₄ is 1.338 moles.
What are moles?
The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
To calculate the moles
The molar mass of SiH₄ is 32.12 g
The mass of SiH₄ is 43.0 g
Thus, the number of moles in the 4.30 g of SiH₄ is 1.338 moles.

Answers
Answer:
Sea floor spreading
Explanation:
In case of a divergent plate motion, two plates move away from another. Due to this motion, there occurs separation of the seafloor, resulting in the addition of new materials to the crust along the mid oceanic ridge. This mid oceanic ridge marks the boundary of separation of the oceanic plates. It often generates deep focus earthquakes and forms volcanoes or chains of volcanic arcs.
Thus, the separation of the two plates under water causes seafloor spreading, and the magma fills the space along the mid oceanic ridge.
