Nitrogen , oxygen , lithium and potassium. i am not sure though.
The answer is d, because the simplest form of C4H10 is C2H5 which is the empirical formula
Answer:
2.5 mole of O2
Explanation:
From the equation we see that we need 5 molecules of oxygen to react with 2 molecules of C2H2.
This means that 5 moles of oxygen molecules are needed to completely react with 2 moles of C2H2, because a mole is a unit of particle count.
From that we can infer that to react with 1 mole of C2H2 we need half of 5 moles of oxygen - so 2.5 mole of oxygen molecules.
Answer:
Longer hydrocarbon molecules have a stronger intermolecular force. More energy is needed to move them apart so they have higher boiling points . This makes them less volatile and therefore less flammable
The answer is a, because the question is referring to partial pressures. Partial pressures are a mere sum, no halving or doubling of anything is necessary.
So, A
Hope this helped :)
