Answer:
The answer to your question is 0.186 moles of CO₂
Step-by-step explanation:
Data
Volume = 2.7 L
Temperature = 24°C
Pressure = 57.2 kPa
moles of CO₂ = ?
Process
1.- Calculate the moles of Propane, use the ideal gas formula
PV = nRT
n = PV / RT
- Convert temperature to °K
°K = 273 + 24 = 297
- Convert pressure to atm
1 atm ----------------- 101325 Pa
x ------------------ 57200 Pa
x = (57200 x 1)/101325
x = 0.56 atm
- Substitution
n = (0.56)(2.7) / (0.082)(297)
- Simplification
n = 1.512 / 24.354
- Result
n = 0.062 moles
2.- Balanced the chemical reaction
C₃H₈ + 5O₂ ⇒ 3CO₂ + 4H₂O
3.- Calculate the moles of Carbon dioxide
1 moles of C₃H₈ ------------------ 3 moles of CO₂
0.062 moles ------------------- x
x = (0.062 x 3) / 1
x = 0.186 moles
The answer would be c trust me
You wanna divide both sides by the numeric factor on the left side, solve.
X=13
Answer:
13/20
Step-by-step explanation:
12/20-4/20+5/20=
8/20+5/20=
13/20
Answer:
A slope triangle is an imaginary triangle that helps you find the slope of a line or a line segment. The hypotenuse of the triangle (the diagonal) is the line you are interested in finding the slope of. The two 'legs' of the triangle are the 'rise' and 'run' used in the slope formula. Slope = rise/run.
Answer:
7.5 days
Step-by-step explanation:
A working = 10 days
AB working = 4 days
AB = 4 --> 10B = 4
/10 /10
B = .4
AB = 3
A(.4) = 3
/.4 /.4
A working alone = 7 .5 days
<em>*pretty much solve for B and then equal AB to the amount of days the worked together before B left, 3 days, then it gives you the amount of time A must work to finish the house alone*</em>
