Approximate molecular masses:
Molecular mass of C = 12
Molecular mass of H = 1
Let n = moles required for CH₂.
Then
nCH₂ = 98
n(12 + 2*1) = 98
14n = 98
n = 7
Answer: The molecular formula is 7CH₂
Answer: I believe it's C

Answer:
chemical change
Explanation:
electrolysis process by which electric current is passed through a substance to effect a chemical change.
It looks like it is going by 25's so I would say 22.75 mL
Answer:
So for your question, the Periodic Table tells us that sodium has an Atomic Number of 11, so there are 11 protons and 11 electrons. The Periodic Table tells us that sodium has an Atomic Mass of ≈23. So there are 23 - 11 = 12 neutrons.
