Answer:
The correct answer is: a. Southern California and Australia.
Explanation:
The solar power, in order to be more efficient and more productive, needs to be produced in places that have a lot of sunny days throughout the year. So the wisest and most practical thing to do is to install solar panels at places that are warm and sunny for most of the year. The southern part of California and most of Australia would be excellent choices for something like this. Both places have predominantly warm weather throughout the year, and more important, they have a lot of sunny days throughout the year. That provides the perfect conditions for harvesting the solar energy and use it as an energy source.
they are the lithosphere, hydrosphere,and biosphere.

Answer : The ratio of hydrogen and oxygen in water is, (2:1)
Explanation :
As we know that the chemical formula of water is, .
In , there are 2 atoms of hydrogen and 1 atom of oxygen.
As we are given that the volume of water is, 2 L. So, there is no matter what is the volume of water that means there is no role of volume of water.
The ratio of hydrogen and oxygen in water is, (2:1)
Thus, in 2 L volume of water, the ratio of hydrogen and oxygen in water is also same that is, (2:1)
The mass in grams of 8.94×10²² formula units of CuF₂ is 15.07 g
<h3>Avogadro's hypothesis </h3>
6.02×10²³ formula units = 1 mole of CuF₂
But
1 mole of CuF₂ = 101.5 g
Thus,
6.02×10²³ formula units = 101.5 g of CuF₂
<h3>How to determine the mass of 8.94×10²² formula units of CuF₂</h3>
6.02×10²³ formula units = 101.5 g of CuF₂
Therefore,
8.94×10²² formula units = (8.94×10²² × 101.5 ) / 6.02×10²³
8.94×10²² formula units = 15.07 g of CuF₂
Thus, 8.94×10²² formula units are present in 15.07 g of CuF₂
