Mountains surround mono laks forming a closed hydrological basin--water fows into the lake, but it doesn't flow out. The only way for water to leave Mono Lake is through evaporation. ... Because the lake has no outlet, it is naturally saline.
Answer:
0.287 M
Explanation:
Multiply the concentration of each solution by the volume of each (in liters) to get the moles of NaOH in that solution.
0.15 M • 5.4000 L = 0.81 mol NaOH
4.0 M • 0.2012 L = 0.80 mol NaOH
Add the mol of NaOH together to get the total --> 0.81 + 0.80 = 1.61 mol NaOH
Divide by the total volume of solution (5400.0 mL + 201.2 mL = 5,601.2 mL = 5.6012 L)
1.61 mol / 5.6012 L = 0.287 M NaOH

Answer:
The answer is A
Explanation:
Because . . .
- A is correct because scientist make their statements by using their observations and tools to measure.
- B is incorrect people's opinions are not facts! Plus, opinions can be wrong.
- C is incorrect because that book can be outdated and not every answer is in a book.
- D is absolutely incorrect because guessing a "right" answer can be wrong. For example, if you were a scientist and you guessed a treatment for coronavirus, you will defiantly get fired because you don't have evidence or logic to back up your answer. In addition, if people used ur "treatment" the one you have guessed as the "right" answer, you can put people's lives in danger and they can possibly die. You will defiantly be responsible for it and be put into jail.
