The answer is (3) carbon atoms. For 2-butanol, it contains single bonds only and with C, O, H atoms. For 2-butene, it contains single bonds and double bonds both. And contains C, H atoms.
Answer:
Hey there!
Four things increasing temperature:
Cars, Busses, Motorcycles
Greenhouse Gases
Factories
Non-renewable energy sources
Four things we can do:
Ride a bike instead of a car
Try using solar panels, and wind energy

Try reusing and recycling.
Let me know if this helps :)
0.074Hz is the answer to that

Answer:
a) 0.525 mol
b) 0.525 mol
c) 0.236 mol
Explanation:
The combustion reactions (partial and total) will be:
C₇H₁₆ + (15/2)O₂ → 7CO + 8H₂O
C₇H₁₆ + 11O₂ → 7CO₂ + 8H₂O
---------------------------------------------------
2C₇H₁₆ + (37/2)O₂ → 7CO + 7CO₂ + 16H₂O
It means that the reaction will form 50% of each gas.
a) 0.525 mol of CO
b) 0.525 mol of CO₂
c) The molar mass of heptane is: 7*12 g/mol of C + 16*1 g/mol of H = 100 g/mol
So, the number of moles is the mass divided by the molar mass:
n = 11.5/100 = 0.115 mol
For the stoichiometry:
2 mol of C₇H₁₆ -------------- (37/2) mol of O₂
0.115 mol of C₇H₁₆ --------- x
By a simple direct three rule:
2x = 2.1275
x = 1.064 mol of O₂
Which is the moles of oxygen that reacts, so are leftover:
1.3 - 1.064 = 0.236 mol of O₂
