Explanation:
Sup Wayne I need this answer too.
Answer:
They have fewer hydrogen atoms attached to the carbon chain than alkanes
Explanation:
Let's compare ethane (an alkane) with ethene (an alkene) and ethyne (an alkyne):
- Ethane's formula is C₂H₄, while ethene's is C₂H₄ and ethyne's C₂H₂.
As you can see, alkenes and alkynes have fewer hydrogen atoms attached to the carbon chain due to them having multiple bonds between the carbon atoms.
Answer:
Ok so, I think I have it, but it might not be right, but 16 grams of oxygen
Explanation:
2H+O=H2O
36gH2O x 1mol/18g(molar mass of water)= 2 moles of water
20 grams of H2 x 1/2= 10 moles of H2
2 moles of H2 react with 1 mole of O2 to produce 2 moles of water, so...
1 mole O2 x 16g/mole = 16 g O2
