Answer:

152.4 g of O₂ are consumed.

Explanation:

We start from the combustion reaction:

C₃H₈  +  5O₂  →  3CO₂  +  4H₂O

We convert the mass of propane to moles:

41.9 g . 1mol /44g = 0.952 moles

Ratio is 1:5. 1 mol of propane consumes 5 moles of oxygen at propane combustion

Then, 0.952 moles may consume (0.952 . 5) /1 = 4.76 moles.

We convert moles to mass → 4.76 mol . 32g/mol = 152.4 g

If 1.20 moles of an ideal gas occupy a volume of 18.2 l at a pressure of 1.80 atm, what is the temperature of the gas, in degree
scoundrel [369]

We can calculate for temperature by assuming the equation for ideal gas law:

P V = n R T

Where,

P = pressure = 1.80 atm

V = volume = 18.2 L

n = number of moles = 1.20 moles

R = gas constant = 0.08205746 L atm / mol K

Substituting to the given equation:

T = P V / n R

T = (1.8 atm * 18.2 L) / (1.2 moles * 0.08205746 L atm / mol K)

T = 332.70 K

We can convert K unit to ˚C unit by subtracting 273.15 to Kelvin, therefore

T = 59.55 ˚<span>C</span>

Does the identity of gas matter when predicting its behavior why or why not?
just olya [345]

Answer: The gas phase is unique among the three states of matter in that there are some simple models we can use to predict the physical behavior of all gases—independent of their identities. We cannot do this for the solid and liquid states. ... Gas particles do not experience any force of attraction or repulsion with each other.
