It was named the Qumran seas scrolls.
Answer:
=C₄H₄O₂
Explanation:
Given the empirical formula of a molecule, the he the quotient of the molecular mas and and the empirical mass=constant.
84.0 g/mol/mass of(C₂H₂O)=constant
=84/(12×2+1×2×16)
=84/42
=2
Therefore, the molecular formula is (C₂H₂O)₂=C₄H₄O₂
Answer: The remains of plants and animals are called organic matter.
Explanation:
Answer:
This is all true if the atom has to be neutral.
Also what does V mean?
