Answer:
I believe 11 is B 12 is C 13 is B and 14 is C
Answer:
D) 373 mm Hg.
Explanation:
We can solve this problem by keeping in mind<em> Dalton's law of partial pressures</em>, which states that the total pressure of a mixture of gases is equal to the sum of each gas' partial pressures. In other words, for this case:
- Total Pressure = Ne Pressure + CO₂ Pressure + O₂ Pressure + H₂ Pressure
- 1245 mm Hg = Ne Pressure + 145 mm Hg + 228 mm Hg + 499 mm Hg
The answer is option D) 373 mm Hg.
The answer is (4) heptane. Saturated hydrocarbon means that there is no double bonds between the carbon atoms. For propene and butene, there is double bond. For ethyne, there is triple bond.
