Answer: methane
✌
Explanation:
methane
Natural gas is composed mostly of methane, but it also contains small amounts of ethane, propane, butane, and pentane. Methane, a combination of hydrogen and carbon, is formed when plants and animals (organic matter) are trapped beneath the sedimentary layers of the earth.
Answer:
3.60 mol CO₂
Explanation:
Balanced chemical reaction:
2CO + O₂ ⇒ 2CO₂
The molar ratio between CO₂ and CO is 1:1
2CO₂/2CO = CO₂/CO
Thus, the moles of CO₂ produced from 3.60 moles of CO is 3.60 moles:
(3.60 mol CO)(CO₂/CO) = 3.60 mol CO₂
Answer:
1 L
Explanation:
Use Boyle's Law, which is defined as:
p1v1 = p2v2
p1 = 3atm
v1 = 5.2L
p2 = 15atm
v2 = ?
We are solving for v2 because all other variables are given.
p1v1 = p2v2
(3atm)(5.2L) = (15atm)(v2)
v2 = (3)(5.2) / (15) = 1.04 L ≈ 1 L
First, we'll balance the equation
C3H8 + 5O2 --> 3CO2 + 4H2O
Next, we know that a gas at stp occupies 22.4 liters/mole, so we can find the number of moles of oxygen gas.
15 liters O2 * (1 mole O2)/(22.4 liters O2) = 0.67 moles O2
Now we know from our balanced equation that there are 3 moles of CO2 per mole of O2, so we can find the number of moles of CO2 we produce.
0.67 moles O2 * (3 moles CO2/5 moles O2) = 0.40 moles CO2
Now, we have the number of moles of CO2, and we know that one mole occupies 22.4 liters, we can find the number of liters
.40 moles CO2 * (22.4 liters CO2)/(1 mole CO2) = 9.0 liters of CO2
The answer is D
