C2 H4+ 3O2= 2CO2+ 2H2O
How many moles of methane will be burnt to produce 0.1 of water

0.05mole

Explanation:

C2H4+ 3O2 —> 2CO2 + 2H2O

From the equation, 1mole of ethene produced 2 moles of H2O.

Therefore, Xmol of ethene will produce 0.1mol of H2O i.e

Xmol of ethene = 0.1/2 = 0.05mole

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

the answer is   c.) 1575 j.
