Answer: ethane, pentane, heptane, octane
Explanation: Boiling point is the temperature at which vapor pressure of the liquid becomes equal to atmospheric pressure.
Boiling point depends on the strength of inter molecular forces. The molecules of hydrocarbons are bonded through weak vanderwaal's forces. As the length of carbon chain increases, the surface area increases and thus the vanderwaal forces increases, thus more heat is to be supplied to break the bonds and thus there is an increase in the boiling point.
IF magnesium sulfide reacts with oxygen in the air it will produce
magnesium oxide + sulfur (IV) oxide
<u><em>explanation</em></u>
magnesium sulfide burn in oxygen to produce magnesium oxide and sulfur (iv) oxide according to the equation below
2MgS +3O2 →2MgO +2SO2
that is 2 moles of MgS react with 3 moles of O2 to produce 2 moles of MgO and 2 moles of SO2
Answer:
Strong acids ionize completely in aqueous solutions while weak acids release a few ions in aqueous solutions.
Explanation:
Pyruvate cannot be a final electron acceptor in bacterial aerobic or anaerobic respiration except Fe3+,rather, pyruvate is an electron donor. Whereas Sulfur is the electron acceptor in anaerobic respiration(respiration in absence of oxygen). Hydrogen ions, Fe3+ and oxygen are final electron acceptor in aerobic respiration.( Respiration in presence of oxygen).
