64/16 = 4 so four molecules
Hello!
The Sun is the main source of providing energy for the satellites. There are solar panels on the satellites to get solar energy from the sun. The sun does provide solar energy and since it's the main source of energy for the satellites, that leaves you with your answer which is solar energy.
I hope this helped!
I am, yours most sincerely,

Answer:
Explanation:
Molar mass of NaCl = 58.44 g/mol
Mass of NaCl = 195 g
Volume of solution = 4.05 L
Molarity of solution is
The molarity of the solution is
Moles of NaCl = 4.63 mol
Volume is given by
The volume of the solution that contains the required amount NaCl is
Volume of solution = 
Moles of solution is given by
The number of moles of NaCl is .
I think the correct answer from the choices listed above is option B. A Bronsted-Lowry acid is a proton donor. Let us consider a chemical reaction between HCl and NaOH. The hydroxide ions in the NaOH are bases because they accept hydrogen ions from acids to form water. An acid produces hydrogen ions in solution by giving a proton to the water molecule. So, the answer is HCN.
This
electronic transition would result in the emission of a photon with the highest
energy:
4p
– 2s
<span>This
can be the same with the emission of 4f to 2s which would emit energy in the
visible region. The energy in the visible region would emit more energy than in
the infrared region which makes this emission to have the highest energy.</span>
