Answer:
england
Step-by-step explanation:
Since K is in the interior of the angle, this means we can use the angle addition postulate.
Angle LMN = (angle LMK) + (Angle KMN)
Angle LMN = (52 degrees) + (12 degrees)
Angle LMN = (52 + 12) degrees
Angle LMN = 64 degreesSee the attached figure for an example of what this could look like.
Answer:
The amount earned by Josie was $13.75 and the amount earned by her brother was $16.25
Step-by-step explanation:
Let
x ----> amount earned by Josie
y ---> amount earned by her brother
we know that
------> equation A
-----> equation B
Solve the system by substitution
Substitute equation A in equation B
solve for y
Find the value of x
therefore
The amount earned by Josie was $13.75 and the amount earned by her brother was $16.25
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
