C3H8 + 5O2 → 3CO2 + 4H2O .
This reaction is balanced correctly because number of atoms on reactant side and product side are same.
Lol I don’t have snap. But I’m only texting this cause this app wants me to answer some questions. But! Lol have a great day/night
<span>a. True. Methane is the chemical that is most abundant in natural gas.

Answer:
600.7 moles
Explanation:
Applying,
PV = nRT................... Equation 1
Where P = Pressure of oxygen, V = Volume of oxygen, n = number of moles, R = molar gas constant, T = Temperature.
make n the subject of the equation
n = PV/RT............... Equation 2
From the question,
Given: P = 190 atm, V = 35 L, T = 135 K
Constant: R = 0.082 atm.dm³/K.mol
Substitute these values into equation 2
n = (190×35)/(135×0.082)
n = 600.7 moles of xygen
When water reaches its boiling point and turns into water vapor, the molecular structure of water remains the same. It is only the state of the substance that is changed in this process. I hope this helps you
