Chloromethane has a boiling point of -11.56°F
Oxygen has a boiling point of -297.3°F
<u>Sodium chloride has a boiling point of 2,669°F</u>
Isopropyl alcohol has a boiling point of 180.5°F
<u><em>So sodium chloride has the highest boiling point.</em></u>
B. Erosion, weathering, and deposition
Answer:
2.5L [NaCl] concentrate needs to be 4.8 Molar solution before dilution to prep 10L of 1.2M KNO₃ solution.
Explanation:
Generally, moles of solute in solution before dilution must equal moles of solute after dilution.
By definition Molarity = moles solute/volume of solution in Liters
=> moles solute = Molarity x Volume (L)
Apply moles before dilution = moles after dilution ...
=> (Molarity X Volume)before dilution = (Molarity X Volume)after dilution
=> (M)(2.5L)before = (1.2M)(10.0L)after
=> Molarity of 2.5L concentrate = (1.2M)(10.0L)/(2.5L) = 4.8 Molar concentrate
It is A).
Electrons are negatively charged and an anion is a negatively charged ion so that means there is more electrons(negative charge) than protons(positive charge) in an anion
