Answer: Hydro-electricity
Explanation: After all it is technology right. The population can use the waves even the tides of the ocean's water to create electricity which is reliable. of course in the beginning it will be expensive but the result will be effective useful. The area having a dry climate could be because of the winds that blow precipitating clouds away but they can have a stable climate by planting more trees where rain can be processed within the geographical location. Finally, the problem of water supply can be fixed by installing water pipes to transport water to the community but in the process, water can be filtered or cleansed to prevent some diseases and social issues/calamities.
all credit to geography

Data:
Molar Mass of NaOH = 40 g/mol
Solving: <span>According to the Law Avogradro, we have in 1 mole of a substance, 6.02x10²³ atoms/mol or molecules
</span>
1 mol -------------------- 6.02*10²³ molecules
y mol -------------------- 2.70*10²² molecules
6.02*10²³y = 0.270*10²³
Solving: <span>Find the mass value now
</span>
40 g ----------------- 1 mol of NaOH
x g ------------- 0.04 mol of NaOH
Answer:
The mass is 1.6 grams
not double replacement
it will be synthesis
they are fusing the two elements

Depending on the forces (negative or positive), if opposite, they will attract, if the same, they will repel
Answer:
diffusion
Explanation:
Diffusion can be defined as the net movement of particles from a high concentration to a low concentration. This sounds like the most plausible word in this case.
